CHAPTER 1
Hardware Installation and Connection
This chapter shows you how to install and connect the Switch.
1.1 Installation Scenarios
The Switch can be placed on a desktop or rack-mounted on a standard EIA rack. Use the rubber
feet in a desktop installation and the brackets in a rack-mounted installation.
Note: For proper ventilation, allow at least 4 inches (10 cm) of clearance at the front and
3.4 inches (8 cm) at the back of the Switch. This is espec ial l y important for
enclosed rack installations.
1.2 Desktop Installation Procedure
1Make sure the Switch is clean and dry.
2Set the Switch on a smooth, level surface strong enough to support the weight of the Switch and
the connected cables. Make sure there is a power outlet nearby.
3Make sure there is enough clearance around the Switch to allow air circulation and the attachment
of cables and the power cord.
1.3 Mounting the Switch on a Rack
The Switch can be mounted on an EIA standard size, 19-inch rack or in a wiring closet with other
equipment. Follow the steps below to mount your Switch on a standard EIA rack using a ra ck-
mounting kit.
1.3.1 Rack-mounted Installation Requirements
• Two mounting brackets.
• Eight M3 flat head screws and a #2 Philips screwdriver.
• Four M5 flat head screws and a #2 Philips screwdriver.
Failure to use the proper screws may damage the unit.
Chapter 1 Hardware Installation and Connection
MGS3750-28F User’s Guide

1.3.1.1 Precautions
• Make sure the rack will safely support the combined weight of all the equipment it contains.
• Make sure the position of the Switch does not make the rack unstable or top-heavy. Take all
necessary precautions to anchor the rack securely before installing the unit.
1.3.2 Attaching the Mounting Brackets to the Switch
1Po sition a mounting bracket on one side of the Switch, lining up the four screw holes on the brack et
with the screw holes on the side of the Switch.
Figure 1 Attaching the Mounting Brackets
2Using a #2 Philips screwdriver, install the M3 flat head screws through the mounting bracket holes
into the Switch.
3Repeat steps 1 and 2 to install the second mounting bracket on the other side of the Switch.
4You may now mount the Switch on a rack. Proceed to the next section.
1.3.3 Mounting the Switch on a Rack
1Position a mounting bracket (that is already attached to the Switch) on one side of the rack, lining
up the two screw holes on the bracket with the screw holes on the side of the rack.

CHAPTER 2
Hardware Overview
This chapter describes the front panel and rear panel of the Switch and shows you how to make the
hardware connections.
2.1 Front Panel
The following figure shows the front panel of the Switch.
Figure 3 MGS3750-28F Front Panel: AC/DC Model
The following table describes the port labels on the front panel.
2.1.1 Console Port
For local management, y ou can use a computer with terminal emulation software configured to the
following parameters:
Dual Personality Interfaces
SFP or SFP+ Slots
Console Port
Power Connection
Table 1 Front Panel Connections
LABEL DESCRIPTION
Power
Connection Connect an appropriate power supply to this port.
SFP or SFP+
Slots Use SFP or SFP+ transceivers in these slots for fiber-optic or copper connections to a
computer, a hub, a switch or a router. You can also insert a SFP+ Direct Attach Copper
(DAC) in the SFP+ Slot.
Four Dua l
Personality
Interfaces
Each interface has one 10/100/1000 BASE-T RJ-45 port and one transceiver slot. You can
activate one port or one transceiver slot at a time.
• Four 10/100/1000 BASE-T RJ-45 Ports:
Connect these ports to high-bandwidth backbone network Ethernet switches using 10/
100/1000G BASE-T compatible copper cables.
• Four Transceiver Slots:
Use mini-GBIC or SFP transceivers in these slots for connections to backbone Ethernet
switches.
Console Port The console port is for local configu ration of the Switch.
Chapter 2 Hardware Overview
MGS3750-28F User’s Guide

• VT100
• Terminal emulation
• 115200 bps
• No parity, 8 data bits, 1 stop bit
• No flow control
Connect the male 9-pin end of the console cable to the console port of the Switch. Connect the
female end to a serial port (COM1, COM2 or other COM port) of your computer.
2.1.1.1 Default Ethernet Negotiation Settings
The factory default negotiation settings for the Gigabit ports on the Switch are:
• Speed: Auto
•Duplex: Auto
• Flow control: Off
• Link Aggregation: Disabled
2.1.1.2 Auto-crossover
All ports are auto-crossover, that is auto-MDIX ports (Media Dependent Interface Crossover), so
you may use either a straight -through Ethernet cable or crossover Ethernet cable for all Gigabit port
connections. Auto-crossover ports automatically sense whether they need to function as crossover
or straight ports, so crossover cables can connect both computers and switches/hubs.
2.1.2 Transceiver Slots
These are slots for mini-GBIC (Gigabit Interface Converter) transceivers or 100 Mbps Small Form-
factor Pluggable (SFP) transceivers. A transceiver is a single unit that houses a transmitter and a
receiver. The Switch does not come with transceivers. You must use transceivers that comply with
the SFP Transceiver MultiSource Agreement (MSA). See the SFF committee’s INF-8 074i
specification Rev 1.0 for details.
You can change transceivers while the Switch is operating. You can use different transceivers to
connect to Ethernet switches with different types of fiber-optic or even copper cable connectors.
To avoid possible eye injury, do not look into an operating fiber-optic
module’s connectors.
• Type: SFP connection interface
• Connection speed: 1 Gigabit per second (Gbps) or 1 Megabit per second (Mbps)
2.1.2.1 Transceiver Installation
Use the following steps to install a mini-GBIC transceiver (SFP module).
1Insert the transceiver into the slot with the exposed section of PCB board facing down.
2Press the transceiver firmly until it clicks into place.
Chapter 2 Hardware Overview
MGS3750-28F User’s Guide

3The Switch automatically detects the installed transceiver. Check the LEDs to verify that it is
functioning properly.
4Close the transceiver’s latch (latch styles v ary).
5Connect the fiber optic cables to the transceiver.
Figure 4 Transceiver Installation Example
Figure 5 Connecting the Fiber Optic Cables
2.1.2.2 Transceiver Removal
Use the following steps to remove a mini-GBIC transceiver (SFP module).
1Remove the fiber optic cables from the transceiver.
2Open the transceiver’s latch (latch styles vary).
3Pull the transceiver out of the slot.

2.1.3 Power Connector
Make sure you are using the correct power source as shown on the panel and that no objects
obstruct the airflow of the fans.
Use the following procedures to connect the Switch to a power source after you have installed it.
Note: Check the power supply requirements on the panel, and make sure you are using
an appropriate power source.
Keep the power supply switch and the Switch’s power switch in the OFF
position until you come to the procedure for turning on the power.
Use only power wires of the required diameter for connecting the Switch to a power supply.
2.1.3.1 AC Power Connection
Connect the female end of the power cord to the power socket of your Switch. Connect the other
end of the cord to a power outlet.
2.1.3.2 DC Power Connection
The Switch uses a single ETB series terminal block plug with four pins which allows you to connect
up to two separate power supplies. If one power supply fails the system can operate on the
remaining power supply. Use two wires to connect to a single terminal pair, one wire for the positive
terminal and one wire for the negative terminal.
Note: The current rating of the power wires must be greater than 20 Amps. The power
supply to which the Switch connects must have a built-in circuit breaker or switch
to toggle the power.
Note: When installing the power wire, push it firmly into the terminal as deep as possible
and make sure that no exposed (bare) wire can be seen or touched.
Exposed power wire is dangerous. Use extreme care when connecting a
DC power source to the device.
To connect a power supply:
1Use a screwdriver to loosen the terminal block captive screws.
2Connect one end of a power wire to the Switch’s RTN (return) pin and tighten the captive screw.
3Connect the other end of the power wire to the positive terminal on the power supply.
4Connect one end of a power wire to the Switch’s -48V (input) pin and tighten the captive screw.
5Connect the other end of the power wire to the negative terminal on the power supply.
6Insert the terminal block plug in the Switch’s terminal block header.

6.2 Static Mac Forwarding
Manually add dynamic, static, blackhole, and permanent MAC addresses.
A static MAC address is an address that has been manually entered in the MAC address table. Static
MAC addresses do not age out. When you set up static MAC address rules, you are setting static
MAC addresses for a port. This may reduce the need for broadcasting.
Static MAC address forwarding together with port security allow only computers in the MAC address
table on a port to access the Switch.
A blackhole port drops traffic without notifying the sources.

6.3.1 Spanning Tree Configuration
Use the Spanning Tree Configuration screen to activate one of the STP modes on the Switch.
Click Configuration in the upper right corner of Spanning Tree Protocol Status screen.
The Switch supports Spanning Tree Protocol (STP), Rapid Spanning Tree Protocol (RSTP) and
Multiple Spanning Tree Protocol (MSTP) as defined in the following standards.
• IEEE 802.1D Spanning Tree Protocol
• IEEE 802.1w Rapid Spanning Tree Protocol
• IEEE 802.1s Multiple Spanning Tree Protocol
Hello Time (second) This is the time interval (in seconds) at which the root switch transmits a configuration
message. The root bridge determines Hello Time, Max Age and Forwarding Delay.
Max Age (second) This is the maximum time (in seconds) the Switch can wait without receiving a
configuration message before attempting to reconfigure.
Forwarding Delay
(second) This is the time (in seconds) the root switch will wait before changing states (that is,
listening to learning to forwarding).
Note: The listening state does not exist in RSTP.
Topology Changed
Times This is the number of times the sp anning tree has been reconfigured.
Port This field displays the number of the port on the Switch.
Active This field displays whether Global Spanning Tree is activated or not.
Pathcost Path cost is the cost of transmitting a frame on to a LAN through that port. It is
recommended to assign this value according to the speed of the bridge. The slower
the media, the higher the cost.
Priority Configure the priority for each port here.
Priority decides which port should be disabled when more than one port forms a loop
in a switch. Ports with a higher priority numeric value are disabled first. The allowed
range is between 0 and 255 and the default value is 128.
Role This field displays the role of the port in STP.
•Root - A forwarding port on a non-root bridge, which has the lowest path cost and
is the best port from the non-root bridge to the root bridge. A root bridge does not
have a root port.
•Designated - A forwarding port on the design ated bridge for each connected LAN
segment. A designated bridge has the lowest path cost to the root bridge among
the bridges connected to the LAN segment. All the ports on a root bridge (root
switch) are designated ports.
•Alternate - A blocked port, which has a best alternate path to the root bridge.
This path is different from using the root port. The port moves to the forwarding
state when the desi gnated port for the LAN segment fails.
•Backup - A blocked port, which has a backup/redundant path to a LAN segment
where a designated port is already connected when a switch has two links to the
same LAN segment.
•Disabled - Not strictly part of STP. The port can be disabled manually.
State If STP (Spanning Tree Protocol) is enabled, this field displa ys the STP state of the port.
If STP is disabled, this field displays FORWARDING if the link is up, otherwise, it
displays STOP.

LABEL DESCRIPTION
Status Click Status to go back to the Spanning Tree Protocol Status screen.
Bridge Priority Bridge priority is used in determining the root switch, root port and designated port.
The switch with the highest priority (lowest numeric value) becomes the STP root
switch. If all switches have the same priority, the switch with the lowest MAC address
will then become the root switch. Select a value from the drop-down list box.
The lower the numeric value you assign, the higher the priority for this bridge.
Bridge Priority determines the root bridge, which in turn determines Hello Time, Max
Age and Forwarding Delay.
Hello Time This is the time interval in seconds between BPDU (Bridge Protocol Data Units)
configuration message generations by the root switch. The allowed range is 1 to 10
seconds.
Max Age This is the maximum time (in seconds) the Switch can wait without receiving a BPDU
before attempting to reconfigure. All Switch ports (ex cept for designated ports) should
receive BPDUs at regular intervals. Any port that ages out STP information (provided
in the last BPDU) becomes the designated port for the attached LAN. If it is a root
port, a new root port is selected from among the Switch ports attached to the
network. The allowed range is 6 to 40 s econds.
Forwarding Delay This is the maximum time (in seconds) the Switch will wait before changing states.
This delay is required because every switch must receive information about topology
changes before it starts to forward frames. In addition, each port needs time to listen
for conflicting information that would make it return to a blocking state; otherwise,
temporary data loops might result. The allowed range is 4 to 30 seconds.
As a genera l rule:
Note: 2 * (Forward Delay - 1) >= Max Age >= 2 * (Hello Time + 1)

6.10 Link Aggregation
This chapter shows you how to logically aggregate physical links to form one logical, higher-
bandwidth link.
Link aggregation (trunking) is the grouping of physical ports into one logical higher-capacity link.
You may want to trunk ports if for example, it is cheaper to use multiple lower-speed links than to
under-utilize a high-speed, but more costly, single-port link. However, the more ports you
aggregate then the fewer available ports you have. A trunk group is one logical link containing
multiple ports.
The beginning port of each trunk group must be physically connected to form a trunk group.

The following table describes the fields in this screen.
6.11 Port Security
Port security allows only packets with dynamically learned MAC addresses and/or configured static
MAC addresses to pass through a port on the Switch. The Switch can learn up to 16K MAC
addresses in total with no limit on individual ports other than the sum cannot exceed 16K.
For maximum port security, enable this feature, disable MAC address learning and configure static
MAC address(es) for a port. It is not recommended you disable port security together with MAC
address learning as this will result in many broadcasts. By default, MAC address learning is still
enabled even though the port security is not activated.

Parameters
Set the fields below for this policy. You only have to set the field(s) that is related to the action(s) you
configure in the Action field.
Egress Port Type the number of an outgoing port.
Priority Specify a priority level.
DSCP Specify a DSCP (DiffServ Code Point) number between 0 and 63.
TOS Specify the type of service (TOS) priority level.
Bandwidth Specify the bandwidth in kilobit per second (Kbps). Enter a number between 1 and
1000000.
Action Action
Specify the action(s) the Switch takes on the associated classified traffic flow.
Note: You can specify only one action (pair) in a policy rule. To have the Switch take
multiple actions on the same traffic flow, you need to define multiple classifiers
with the same criteria and apply different policy rules.
Say you have several classifiers th at identify the same traffic flow and you specify a
different policy rule for each. If their policy actions conflict (Discard the packet,
Send the packet to the egress port and Rate Limit), the Switch only applies the
policy rules with the Discard the packet and Send the packet to the eg ress port
actions depending on the classifier names. The longer the classifier n a me, the higher
the classifier priority. If two classifier names are the same length, the bigger the
character, the higher the classifier priority. The lowercase letters (such as a and b)
have higher priority than the capitals (such as A and B) in the classifier name. For
example, the classifier wit h the name of class 2, class a or class B takes priority over
the classifier with the name of class 1 or class A.
Let’s say you set two classifiers (Class 1 and Class 2) and both identify all traffic from
MAC addre s s 11:22:33:44:55:66 on port 3.
If Policy 1 applies to Class 1 and the action is to drop the packets, Policy 2 applies to
Class 2 and the action is to forward the packets to the egress port, the Switch will
forward the packets.
If Policy 1 applies to Class 1 and the action is to drop the packets, Policy 2 applies to
Class 2 and the action is to enable bandwidth limitation, the Switch will discard the
packets immediately.
If Policy 1 applies to Class 1 and the action is to forward the packets to the egress
port, Policy 2 applies to Class 2 and the action is to enable bandwidth limitation, the
Switch will forward the packets.
Forwarding Select No change to forward the packets.
Select Discard the packet to dro p the packets.
Priority Select No change to keep the priority setting of the frames.
Select Set the packet’s 802.1p priority and send the packet to priority queue
to replace the pack et’ s 802.1p priority fie ld with the v alue you set in the Priority field

6.14 Queuing Method
Set queue priority. There are four queuing modes: SPQ, WRR, WFQ, and SP+WFQ. The default
queuing method is SPQ.
Strictly Priority Queuing
Strictly Priority Queuing (SPQ) services queues based on priority only. As traffic comes into the
Switch, traffic on the highest priority queue, Q7 is transmitted first. When that queue empties,
traffic on the next highest-priority queue, Q6 is transmitted until Q6 empties, and then traffic is
transmitted on Q5 and so on. If higher priority queues never empty, then traffic on lower priority
queues never gets sent. SPQ does not automatically adapt to changing network requirements.
Weighted Fair Queuing
Weighted Fair Queuing is used to guarantee each queue's minimum bandwidth based on its
bandwidth weight (portion) (the number you configure in the Weight field) when there is traffic
congestion. WFQ is activated only when a port has more traffic than it can handle. Queues with
larger weights get more guaranteed bandwidth than queues with smaller weights. This queuing
mechanism is highly efficient in that it divides any available bandwidth across the different traffic
queues. By default, the weight for Q0 is 1, for Q1 is 2, for Q2 is 3, and so on.
Diffserv Select No change to keep the TOS and/or DSCP fields in the packets.
Select Set the packet’s TOS fi eld to set the TOS field with the value you configure in

Weighted Round Robin Scheduling (WRR)
Round Robin Scheduling services queues on a rotating basis and is activated only when a port has
more traffic than it can handle. A queue is a given an amount of bandwidth irrespective of the
incoming traffic on that port. This queue then mo ves to the back of the list. The next queue is given
an equal amount of bandwidth, and then mov es to the end of the list; and so on, depending on the
number of queues being used. This works in a looping fashion until a queue is empty.
Weighted Round Robin Scheduling (WRR) uses the same algorithm as round robin scheduling, but
services queues based on their priority and queue weight (the number you configure in the queue
Weight field) rather than a fixed amount of bandwidth. WRR is activated only when a port has
more traffic than it can handle. Queues with larger weights get more service than queues with
smaller weights. This queuing mechanism is highly efficient in that it divides any available
bandwidth across the different traffic queues and returns to queues that have not yet emptied.
Please set the Method of Q0-Q7 to WRR.

a port, the Switch itself sends out an IGMP Gr oup-Specific Query (GSQ) message to
determine whether other hosts connected to the port should remain in the specific
multicast group. This helps speed up the leave process. This defines how many

IGMP Snooping IGMP snoo p ing enables a layer-2 switc h to dynamicall y learn the mem bers of IP
multicast groups. The switch can then forward multicast traffic to ports that are
members of those multicast groups. When a switch receives multicast traffic destined
for multicast groups that it does not know, it either forwards the traffic to all ports or
discards it (depending on the switch and/or the swi tch’s configur ation). IGMP snooping
generates no additional network traffic and allows a switch to handle multicast traffic
more efficiently and effectively.

Security Level Select whether you want to implement authentication and/or encryption for SNMP
communication from this user. Choose:
•noauth -to use the username as the password string to send to the SNMP manager.
This is equivalent to the Get, Set and Trap Community in SNMP v2c. This is the lowest
security le vel.
•auth - to implement an authentication algorithm for SNMP messages sent by this
user.
•priv - to implement authentication and enc ryption for SNMP mess ages sent by this
user. This is the highest security level.
Note: The settings on the SNMP manager must be set at the same security level or higher
than the security level settings on the Switch.
Authentication Select an authentication algorithm. MD5 (Message Digest 5) and SHA (Sec ure Hash
Algorithm) are hash algorithms used to authenticate SNMP data. SHA authentication is
generally considered stronger than MD5, but is slower.
Password Enter the password of up to 32 ASCII characters for SNMP user authentication.
Privacy Specify the encryption method for SNMP communication from this user. You can choose
one of the following:
•DES - Data Encryption Standard is a widely used (but breakable) method of data
encryption. It applies a 56-bit key to each 64-bit block of data.
•AES - Advanced Encryption Standard is another method for data encryption that also
uses a secret key. AES applies a 128-bit key to 128-bit blocks of data.
Password Enter the password of up to 32 ASCII characters for encrypting SNMP packets.
Group SNMP v3 adopts the concept of View-based Access Control Model (VACM) group. SNMP
managers in one group are assigned common access rights to MIBs. Specify in which
SNMP group this user is.
admin - Members of this group can perform all types of system configurat io n, including
the management of administrator accounts.
readwrite - Members of this group have read and write rights, meaning that the user can
create and edit the MIBs on the Switch, except the user account and AAA configuration.
