USB Port You can use the USB port with a flash drive for the following functions:
Provide a centralized network backup location for Autonomous
Management Framework.
Store backup copies of configuration files.
Transfer configuration files between switches that are to have
similar configurations.
Store or transfer log files.
Store or transfer debug files (for example, the output of the SHOW
TECH-SUPPORT command).
Boot the AlliedWare Plus operating system and master
configuration file from flash drive.
Using a flash drive with the switch is optional.
NET MGMT
Ethernet
Management
Port
The switch uses the NET MGMT port as a separate routed eth0 interface.
The interface is not part of the switching matrix, but the switch can route
traffic in or out of the port from the network ports and Ethernet line card.
Here are the guidelines:
The port should only be used for initial configuration and
maintenance access to the chassis.
The NET MGMT port has a standard 8-pin RJ-45 connector and
operates at 10, 100, or 1000 Mbps in either half- or full-duplex
mode.
The default setting for the port is Auto-Negotiation, which sets the
speed and duplex mode automatically. You may disable
Auto-Negotiation and configure the port manually.
The wiring configuration of the NET MGMT port is set automatically
with automatic MDIX detection. You can disable automatic MDIX
detection and set the wiring configuration manually.
The port is referred to as eth0 in the management software.
The minimum cable requirements for the port are listed here:
10 or 100Mbps - Standard TIA/EIA 568-B-compliant Category 3
unshielded cabling.
1000Mbps - Standard TIA/EIA 568-A-compliant Category 5 or TIA/
EIA 568-B-compliant Enhanced Category 5 (Cat 5e) unshielded
cabling.
For instructions on how to configure the NET MGMT port, refer to the
Software Reference for x950 Switch, AlliedWare Plus Operating System.
The Network Management (NET MGMT) port has one Status LED,
described in Table 9.
Chapter 1: Overview
30
Console (RS-232)
Port
You use the Console Port to conduct local management sessions with the
switch. Local management sessions require a terminal or PC with a
terminal emulation program, and the management cable that comes with
the switch. The switch does not need an Internet Protocol (IP) address for
local management sessions because they are not conducted over a
network. For instructions, refer to “Starting a Local Management Session”
on page 160.
Note
The first management session of the switch can be either a local
session or a remote session over your network through the NET
MGMT port. For remote management, the switch uses either its
default IP address 192.168.42.42 or an address assigned to it by a
DHCP server. For instructions on remote management sessions,
refer to the Software Reference for x950 Switches, AlliedWare Plus
Operating System.

eco-friendly
Button
You use the eco-friendly button on the management panel to turn the
LEDs on or off. You might turn off the LEDs when you are not using them
to monitor the switch, to conserve electricity. When the LEDs are off, the
overall power consumption of the chassis is reduced by approximately 2
watts.
The button controls all the port LEDs, except for the L/A LED for the NET
MGMT port. Additionally, the button does not control the LEDs on the
power supplies.
Note
The x950-52XSQ switch does not have the eco-friendly button.

PWR600 AC and DC Power Supplies
The x950 series switch supports the PWR600 AC and PWR600 DC power
supply units.
Here are power supply guidelines:
You can install either one or two power supplies in the switch.
A single power supply can power a fully equipped switch.
Installing two power supplies adds power redundancy.
You can install two PWR600 AC modules, two PWR600 DC
modules, or a combination of the PWR600 AC and PWR600 DC
modules on one switch.
The power supplies are installed in the PSU A and PSU B slots in
the rear panel of the chassis. If you are installing only one power
supply, Allied Telesis recommends installing it in PSU A slot
because that slot does not come with a blank slot cover.
The switch does not come with power supplies. They are
purchased separately.
The power supplies are field-replaceable and hot-swappable. If the
switch has two power supplies and one fails, you do not have to
power off the operational power supply to replace the failed unit.

Designating Ports in the Command Line Interface
The individual ports on the switch are identified with the PORT parameter
in the command line interface of the AlliedWare Plus management
software. The format of the parameter is shown in Figure 17.
Figure 17. PORT Parameter in the Command Line Interface
The three parts of the PORT parameter are described in Table 13.
Table 13. PORT Parameter Format
Number Description
Switch ID Number Identifies the switch’s ID number. Please review
the following:
- The default value is 1.
- Allied Telesis recommends using the default
value for stand-alone switches.
- A stand-alone switch that was previously a
stack member retains its ID number from the
stack.
- The Switch ID LED on the front panel of the
switch always displays “0” when the VCStack
feature is disabled.
Slot Number Identifies whether ports are base ports or ports
on an XEM2 Line Card. Slot number 0 indicates
base ports and slot number 1 indicates ports on
a line card. Refer to Figure 18 on page 41.

rack is safely secured so that it will not tip over. Devices should be
installed in the rack starting at the bottom, with the heavier devices
near the bottom of the rack.
The power outlet should be located near the chassis and be easily
accessible.
The site should allow for easy access to the ports on the front of
the switch, so that you can easily connect and disconnect cables,
and view the port LEDs.
The site should allow for adequate air flow around the unit and
through the cooling vents on the front and rear panels. (The
ventilation direction is from front to back, with the fans on the back
panel drawing the air out of the unit.)
The site should not expose the switch to moisture or water.

Warning
Mounting of the equipment in the rack should be such that a
hazardous condition is not created due to uneven mechanical
loading. E25
Warning
Do not pull the rear of the switch out past the front rack posts. If you
need to position the rear of the switch out past the front of the rack,
you should remove it completely from the rack. E58
Warning
Pull the switch out slowly if you must remove it from the rack for
maintenance. If you pull the switch out past the front of the rack
posts, or if you pull it out too quickly, there is a risk that the weight of
the switch will cause the sliding rail assemblies to fail and cause the
switch to fall out. E59
Caution
Avoid applying excessive force to the cables. E60
Caution
If using long extension bracket(s), secure between the fixed bracket
and short extension bracket - the long extension bracket(s) cannot
be attached directly to the inner rail. E61

Disabling VCStack
The procedure in this section explains how to disable the VCStack feature
so that you can use the unit as a stand-alone switch. In all likelihood you
will not have to perform this procedure because the default setting for the
feature is disabled. A simple way to determine whether the VCStack
feature is enabled or disabled is by viewing the Switch ID LED:
If the LED is displaying “0”, the VCStack feature is already disabled
and the switch is operating as a stand-alone unit. Go to
“Configuring Ports for 40Gbps QSFP+ or 100Gbps QSFP28
Transceivers, or Breakout Cables” on page 166.
If the LED is displaying the number “1” or higher, the VCStack
feature is enabled. You should disable it to use the unit as a stand-
alone switch. For instructions, perform the following procedure.
Caution
You have to reset the switch after disabling the VCStack feature.
Some network traffic may be lost if the device is connected to a live
network. E89
If the switch is powered off, start with step 1. If the switch is powered on,
start with step 3:
1. Power on the switch by connecting AC power cords to the power
supply connectors on the back panel and to AC power sources. Refer
to “Powering On the Switch” on page 156.
2. Wait two minutes for the switch to initialize its management software.
3. Start a local management session on the device. Refer to “Starting a

Cabling Twisted Pair Ports
This section applies to the twisted pair ports on the following products:
x950-28XTQm Switch
XEM2-8XSTm Line Card
XEM2-12XT Line Card
XEM2-12XTm Line Card
Here are the cabling guidelines:
Minimum cable requirements are:
– 100Mbps - Standard TIA/EIA 568-B-compliant
Category 3 unshielded cabling.
– 1/2.5/5Gbps - Standard TIA/EIA 568-A-compliant
Category 5 or TIA/EIA 568-B-compliant Enhanced
Category 5 (Cat 5e) unshielded cabling.
– 10Gbps -Standard TIA/EIA 568-C-compliant
Category 6a unshielded cabling.
The connectors on the cables should fit snugly into the ports, and
the tabs should lock the connectors into place.
The default speed setting for the ports is Auto-Negotiation. This
setting is appropriate for ports connected to network devices that
also support Auto-Negotiation.
The ports must be set to Auto-Negotiation, the default setting, to
operate at 1Gbps, 2.5Gbps, 5Gbps, or 10Gbps.
The ports support full-duplex only.
Do not attach cables to ports of static or LACP port trunks until you
have configure the trunks on the switch. Otherwise, the ports will
form network loops that can adversely affect network performance.

Guidelines to Handling Twisted Pair or Fiber Optic Transceivers
Please review the following guidelines before installing twisted pair or fiber
optic transceivers:
Transceivers are hot-swappable. You can install them while the
switch is powered on.
For a list of supported transceivers, refer to the product data sheet
on the Allied Telesis web site.
The operational specifications and fiber optic cable requirements
are provided in the documents included with the transceivers.
You should install transceivers in XEM2 line cards before
connecting their fiber optic cables.
Fiber optic transceivers are dust sensitive. Always keep the plug in
the optical bores when a fiber optic cable is not installed, or when
you store the transceiver. When you do remove the plug, keep it for
future use.
Repetitive removal or insertion of transceivers can lead to
premature failures.
100Gbps transceivers for XEM2-1CQ Line Cards have handles.
Use the handles when installing or removing transceivers. An
example is shown in Figure 114.
Figure 114. Handle on 100Gbps Transceivers for XEM2-1CQ Line Cards

Troubleshooting
This chapter contains suggestions on how to troubleshoot problems with
the switch.
Note
For further assistance, please contact Allied Telesis Technical
Support at www.alliedtelesis.com/support.
Problem 1: The unit is not receiving power. All the port LEDs and Switch
ID LED are off, and the fans are not operating.
Solutions: Try the following:
Verify that the power cord is securely connected to the power
source and AC connector on the back panel of the switch.
Verify that the DC power wires are securely connected to the
screws on the front panel and to the DC power source unit.
Verify that the power outlet has power by connecting another
device to it.
Try connecting the unit to another power source.
Try a different power cord.
Verify that the voltage from the power source is within the required
levels for your region. The power requirements for the switch are
listed in “Power Specifications” on page 212.
Try replacing the power supply.
Note
Power supplies are hot swappable. If the chassis has two power
supplies and one fails, you can replace the failed unit without having
to power off the operational power supply.
Problem 2: All the port LEDs are off even though the ports are connected
to active network devices.
Solution: The switch might be operating in the low power mode. To toggle
on the LEDs, press the eco-friendly button on the front panel of the switch.
You can also toggle the LEDs off and on with the ECOFRIENDLY LED and
NO ECOFRIENDLY LED commands in the command line interface.
Chapter 12: Troubleshooting

Problem 3: A 1Gbps or 10Gbps fiber optic transceiver in a base port
(ports 1 to 24 for the x950-28XSQ and x950-28XTQm switches, or port 1
to 48 for the x950-52XSQ switch) is unable to establish a link to a network
device.
Solutions: Try the following:
Check that the transceiver is fully inserted in the port.
Verify that the fiber optic cable is securely connected to the port on
the transceiver and the remote network device.
Verify that the remote network device is operating properly.
Verify that the operating specifications of the fiber optic ports on
the transceiver and remote network device are compatible.
Verify that the correct type of fiber optic cabling is being used.
Verify that the port is connected to the correct fiber optic cable.
Try connecting another network device to the fiber optic port using
a different cable. If the port is able to establish a link, then the
problem is with the cable or with the other network device.
Use the switch’s management software to verify that the port is
enabled.
If the remote network device is a managed device, use its
management firmware to determine whether its port is enabled.
If the problem is with two BiDi (bi-directional) transceivers, refer to
their data sheets to verify that their transmission and reception
frequencies are opposite each other. For instance, a BiDi
transceiver that transmits and receives at 1310nm and 1550nm,
respectively, has to be connected to a transceiver that transmits
and receives at 1550nm and 1310nm, respectively. Two BiDi
transceivers will not establish a link if they transmit and receive at
the same frequencies.
Test the attenuation of both directions on the fiber optic cable with
a fiber optic tester to determine whether the optical signal is too
weak or strong.
Problem 4: A 40Gbps or 100Gbps fiber optic transceiver in port 25, 29,
33, or 37 on the x950-28XSQ and x950-28TQm switches or port 49, 53,
57, or 61 on the x950-52XSQ switch cannot establish a link with a network
device.
Solutions: Try the following:
Review the solutions in Problem 3.
Use the SHOW PLATFORM command to confirm that the port is
configured correctly for an 100Gbps fiber optic transceiver. If
necessary, perform “Configuring Ports for 40Gbps QSFP+ or
100Gbps QSFP28 Transceivers, or Breakout Cables” on
x950 Series Installation Guide for Stand-alone Switches
203
page 166.
Changing a port from a 40Gbps transceiver or breakout cable to a
100Gbps transceiver requires resetting the switch. The same is
also true when replacing a 100Gbps transceiver with a 40Gbps
transceiver or breakout cable.
If the problem is with an 100Gbps transceiver, you might need to
adjust the Forward Error Correction (FEC) parameter on the port,
with the FEC command. Refer to the Software Reference for x950
Switch, AlliedWare Plus Operating System.
Problem 5: A 4x10Gbps breakout cable in port 25, 29, 33, or 37 on the
x950-28XSQ and x950-28XTQm switches, or port 49, 53, 57, or 61 on the
x950-52XSQ switch cannot establish links with network devices.
Solutions: Try the following:
Check that the cable is fully inserted in the port in the switch.
Verify that the breakout cables are securely connected to the ports
on the network devices.
Use the SHOW PLATFORM command to confirm that the port is
configured for a breakout cable. If necessary, perform “Configuring
Ports for 40Gbps QSFP+ or 100Gbps QSFP28 Transceivers, or
Breakout Cables” on page 166.
If the port previously had a 100Gbps transceiver, you must reset
the switch after configuring it for a breakout cable.
Problem 6: An XEM2 line card in the expansion slot is not functioning.
Solutions: Try the following:
Visually inspect the card to verify that it is fully inserted into the
expansion slot.
If the problem is with an XEM2-12XTm Card, the switch might have
an earlier version of the AlliedWare Plus software that does not
support the card. The card requires v5.4.9-1 or later. Use the
SHOW VERSION command to display the version number. If
necessary, update the management software.
Try installing the card in a different switch. If it still does not work,
the problem is probably with the card. Replace the card.
Try installing a different card in the switch. If the replacement card
fails to work, the problem is probably with the switch. Contact your
Allied Telesis sales representative for assistance.

Solutions: Try the following:
Verify that the network device connected to the twisted pair port is
powered on and is operating properly.
Verify that the network device operates at a speed supported by
the card. The ports on the XEM2-12XT Card support 100Mbps and
1/10Gbps. The ports on the XEM2-12XTm Card support 100Mbps
and 1/2.5/5/10Gbps. The cards do not support 10Mbps devices.
If the XEM2-12XT Card cannot establish links with 100Mbps
devices, the switch might have an earlier version of the AlliedWare
Plus management software. Support for 100Mbps devices on the
XEM2-12XT Card was added in version 5.4.9-1. Use the SHOW
VERSION command to display the version number. If necessary,
update the management software.
Try connecting another network device to the twisted pair port with
a different cable. If the twisted pair port is able to establish a link,
then the problem is with the cable or the other network device.
Verify that the twisted pair cable does not exceed 100 meters (328
feet).
Verify that you are using the appropriate category of twisted pair
cable. Cable requirements are listed in “Cabling Twisted Pair
Ports” on page 170.
Verify that the port is connected to the correct twisted pair cable.
Note
An 1GBase/10GBase connection may require five to ten seconds to
establish a link.
Problem 9: The switch overheats and shuts down.
Solutions: Try the following:
Verify that the location of the switch allows for adequate airflow.
If the switch is operating, use the SHOW SYSTEM
ENVIRONMENT command in the Privileged Exec mode to verify
that the power supplies and fan modules are operating properly.
x950 Series Installation Guide for Stand-alone Switches

Problem 10: The switch functions intermittently.
Solutions: Try the following:
Use the SHOW SYSTEM ENVIRONMENT command in the
Privileged Exec mode to verify that the input voltage from the
power source to the switch is stable and within the approved
operating range. The unit will shut down if the input voltage
fluctuates above or below the approved operating range.
Use the SHOW SYSTEM ENVIRONMENT command to verify that
the fan modules are operating correctly.
Verify that the location of the switch allows for adequate airflow.
The unit will shut down if it is overheating.
Problem 11: The Switch ID LED in the management panel is flashing “F.”
Solutions: One of the following problems has occurred:
A cooling fan has failed.
The internal temperature of the switch is outside the normal
operating range and the unit might shut down.
