PoE Port Priorities
If the switch determines that the power requirements of the powered
devices exceed its power budget, it will deny power to some ports based
on a system called port priorities. You can use this mechanism to ensure
that powered devices critical to the operations of your network are given
preferential treatment by the switch in the distribution of power should the
demands of the devices exceed the available capacity.
There are three port priority levels:
Critical
High
Low
Ports set to the Critical level, the highest priority level, are guaranteed
power before any of the ports assigned to the other two priority levels.
Ports assigned to the other priority levels receive power only if all the
Critical ports are receiving power. Ports that are connected to your most
critical powered devices should be assigned to this level. If there is not
enough power to support all the ports set to the Critical priority level,
power is provided to the ports based on port number, in ascending order.
The High level is the second highest level. Ports set to this level receive
power only if all the ports set to the Critical level are already receiving
power. If there is not enough power to support all of the ports set to the
High priority level, power is provided to the ports based on port number, in
ascending order.
The lowest priority level is Low. This is the default setting. Ports set to this
level only receive power if all of the ports assigned to the other two levels
are already receiving power. As with the other levels, if there is not enough
power to support all of the ports set to the Low priority level, power is
provided to the ports based on port number, in ascending order.
The GS980EM/10H switch can be operated in two ways; with redundant
power or using all available power. The switch can have up to three
separate external power supplies.
GS980EM Series Installation Guide
29
The GS980EM/10H switch does not use Dynamic Power Management
(DPM). Therefore, the software cannot detect a failure of the PSU and
decide which ports to deny power to. As a result, more ports may be
powered than the unit can restart due to lack of power. In this case, the
switch will deny Low priority ports and to attempt to repower once the CPU
has determined the new power budget. The hardware is connected to
provide the signal based on the number of Power Good indications and
configuration for the software about how many PSUs are required.
The user must designate the ports that should not be reset on the PSUs
failure as High or Critical, because Low priority ports will be shutdown
(either immediately or as a result of rebudgeting). The default PoE priority
for the ports is Low. See “PoE Port Priorities” on page 28 for more
information.
The switch will deny Low priority ports when:
A PSU fails.
A PSU fails and the maximum power used for budgeting is equal to or
less than the new number of PSUs connected.
Both modes allow redundant operation. In both, the ports should be
configured to higher priorities to ensure they do not lose power on
subsequent PSU failures. The difference between the two is that in the
second mode the user is prevented from powering too many ports in the
first place by the Max Budget, which leaves a PSU as a spare.
The software will operate in a mode of operation where the denial of ports
depends upon how many PSUs are connected as shown in Table 6. The
user must configure ports to Critical and High priority and the total wattage
for either should be no more than 240W.
This behavior is not configurable beyond the user configuring Critical, High
and Low priorities. By configuring the port priorities or making full use of all
the available power, the user gets a constant mode of operation that
enables redundant configuration. The software changes the ports that shut
down at each stage of PSU failure.

Example 1:
The GS980EM/10H switch has three PWR300 units. All ports are Low
priority. The total PD load is 600W. One PSU fails, leaving two PSUs. The
following steps occur:
1. The switch stops providing power to all ports because they are all Low
priority.
2. The software takes a few seconds to recalculate the new power
budget based on the two remaining PSUs.
3. After recalculating the new budget, the switch provides power again to
some of the ports, up to 480W.
Example 2:
The GS980EM/10H switch has three PWR300 units.
Critical priority PDs - 200W
High priority PDs - 200W
Low priority PDs - 200W
One PSU fails, leaving two PSUs:
1. The switch stops providing power to the Low priority PDs.
2. The software takes a few seconds to recalculate the new power
budget based on the two remaining PSUs.
3. After recalculating the new budget, the switch provides power again to
Low priority ports if the budget allows.
In this example, the new budget would be 480W (two remaining PSUs).
So there would be 80W available for Low priority PDs.

Console Port
The Console port is an RS232 serial management port. Use the port to
access the AlliedWare Plus management software on the switch to
configure the feature settings or monitor status or statistics. This type of
management uses the management cable included with the unit. It
requires that you be at the physical location of the switch. The switch does
not have to have an IP address for local management.
To establish a local management session with the switch, use the provided
management cable to connect a terminal or a personal computer with a
terminal emulation program to the Console port, which has an RJ-45 style
(8P8C) connector. The cable has RJ-45 style (8P8C) and DB-9 (D-sub 9-
pin) connectors.
The Console port has the following settings:
Default baud rate: 9600 bps (The baud rates of the port are 9600,
19200, 38400, 57600, and 115200 bps.)
Data bits: 8

eco-friendly Command
The eco-friendly command is used to toggle the port LEDs on or off. You
can turn off the LEDs to conserve electricity when you are not monitoring
the device. You can toggle the LEDs with the ECOFRIENDLY LED and
NO ECOFRIENDLY LED commands in the Global Configuration mode of
the command line interface of the AlliedWare Plus management software.
The switch is operating in a low power mode when the LEDs are turned
off. Operating the switch in the low power mode does not interfere with the
network operations of the device.
The management software on the switch has a command that blinks the
LEDs so that you can quickly and easily identify a specific unit among the
devices in an equipment rack. It is the FINDME command. The command
works on the switch even if you turned off the LEDs with the eco-friendly
button or NO ECOFRIENDLY LED command.
Note
Before checking or troubleshooting the network connections to the
ports on the switch, you must always check to be sure that the LEDs
are on by issuing the ECOFRIENDLY LED and NO ECOFRIENDLY
LED commands in the Global Configuration mode in the command
line interface.

Port 11 - PoE IN Pass-through
Port 11 has two functions. First, it can function as a standard Ethernet port,
with all the same Ethernet features and functions as ports 1 to 8. Second,
when connected to a PoE power source, such as a PoE switch or router, it
can also function as a PoE pass-through port. The switch uses the power
from the PoE power source on the port to operate its own switching
functions, and passes remaining power to ports 1 to 8 for powered
devices.
Powered Device
Classes
To use port 11 as a pass-through port, the powered device connected to it
must be from one of the following IEEE 802.3 classes:
IEEE802.3af Class 4
IEEE803.3at Class 6
IEEE803.3bt Class 8
Note
Connecting port 11 to an unsupported class of powered device
might result in unpredictable switch behavior.
Port 11 cannot power the switch or function as a PoE pass-through port if
connected to a Class 3 or lower powered device.
PoE Budget When using port 11 as a pass-through port, the PoE budget of the switch
for ports 1 to 8 depends on the class of the power source connected to it.
The possible budgets are shown in Table 16. For instance, customers who
want the maximum possible PoE budget of 46W for ports 1 to 8 will
connect port 11 to a Class 8 power source.
When port 11 is connected to a Class 4 powered device, the device will
have enough power to function as a switch, but no power for powered
devices on ports 1 to 8.

The switch can also be powered with the PWR90ADP AC/DC adapter.
However, port 11 and the adapter are not load-sharing. If the switch is
connected to a PoE power source on port 11 and also to the AC/DC
adapter, the adapter automatically becomes the primary power source.
PoE on port 11 is placed in a backup state, but the Ethernet function of
port 11 continues to work. If the adapter loses power, the switch will reboot
and the PoE power on port 11 becomes the power source.
Port 11 LEDs The LEDs for port 11 are identified in Figure 9.

PWR90ADP AC/DC Power Adapter
The GS980EM/11PT Switch can be powered two ways. One way is by
connecting a Class 4, 6, or 8 PoE power source to port 11. This is
described in “Port 11 - PoE IN Pass-through” on page 47. The second way
is with the PWR90ADP AC/DC power adapter, shown in Figure 10.
Figure 10. PWR90ADP AC/DC Power Adapter
The PoE budget of the switch for powered devices on ports 1 to 8 differs
depending on how the unit is powered, as explained here:
The switch has a PoE budget of 21W or 46W when port 11 is
connected to a Class 6 or 8 power source device, respectively.
(The switch has no PoE budget when port 11 is connected to a
Class 4 power source.)
The switch has a PoE budget of 62W when powered by the
PWR90ADP AC/DC power adapter.

PoE Port Priorities
If the switch determines that the power requirements of the powered
devices exceed its power budget, it will deny power to some ports based
on a system called port priorities. You can use this mechanism to ensure
that powered devices critical to the operations of your network are given
preferential treatment by the switch in the distribution of power should the
demands of the devices exceed the available capacity.
There are three port priority levels:
Critical
High
Low
Ports set to the Critical level, the highest priority level, are guaranteed
power before any of the ports assigned to the other two priority levels.
Ports assigned to the other priority levels receive power only if all the
Critical ports are receiving power. Ports that are connected to your most
critical powered devices should be assigned to this level. If there is not
enough power to support all the ports set to the Critical priority level, power
is provided to the ports based on port number, in ascending order.
The High level is the second highest level. Ports set to this level receive
power only if all the ports set to the Critical level are already receiving
power. If there is not enough power to support all of the ports set to the
High priority level, power is provided to the ports based on port number, in
ascending order.
The lowest priority level is Low. This is the default setting. Ports set to this
level only receive power if all of the ports assigned to the other two levels
are already receiving power. As with the other levels, if there is not enough
power to support all of the ports set to the Low priority level, power is
provided to the ports based on port number, in ascending order.
Power allocation on the GS980EM/11PT switch is dynamic. The switch
automatically ceases power transmissions on ports if its power budget is at
maximum usage and new powered devices, connected to ports with
higher priorities, become active. Additionally, the switch ceases power
transmissions on lower priority ports if for any reason its PoE budget
decreases and the power requirements of the powered devices exceeds
the new, reduced budget.

eco-friendly Command
The eco-friendly command is used to toggle the port LEDs on or off. You
can turn off the LEDs to conserve electricity when you are not monitoring
the device. You can toggle the LEDs with the ECOFRIENDLY LED and
NO ECOFRIENDLY LED commands in the Global Configuration mode of
the command line interface of the AlliedWare Plus management software.
The switch is operating in a low power mode when the LEDs are turned
off. Operating the switch in the low power mode does not interfere with the
network operations of the device.
The management software on the switch has a command that blinks the
LEDs so that you can quickly and easily identify a specific unit among the
devices in an equipment rack. It is the FINDME command. The command
works on the switch even if you turned off the LEDs with the eco-friendly
button or NO ECOFRIENDLY LED command.
Note
Before checking or troubleshooting the network connections to the
ports on the switch, you must always check to be sure that the LEDs
are on by issuing the ECOFRIENDLY LED and NO ECOFRIENDLY
LED commands in the Global Configuration mode in the command
line interface.

Verifying the PoE Budget
GS980EM/10H This procedure explains how to verify the PoE budget on the
GS980EM/10H switch. The budget is the maximum wattage the switch
has available for the powered devices on its twisted pair ports. The budget
for GS980EM/10H should be 240W for each power supply that meets the
specifications in “PWR300 Power Supply” on page 27.
The procedure assumes you have already started a local management
session on the device. For instructions, refer to “Starting a Local
Management Session” on page 133.
To confirm the PoE budget, perform the following procedure:
1. Enter the ENABLE command at the User Exec mode to move to the
Privileged Exec mode, as shown here:
awplus> enable
awplus#
2. Enter the SHOW POWER-INLINE command at the Privileged Exec
mode prompt, as shown here:
awplus# show power-inline
3. Examine the Nominal Power field in the command output.
It should be 240W, 480W, or 720W depending on the number of power
supplies that are connected. This is the maximum PoE budget for the
powered devices on the ports of the GS980EM/10Hswitch.
To display the status of each PWR300 power supply, use the SHOW
SYSTEM ENVIRONMENT command.
GS980EM/11PT This procedure explains how to verify the PoE budget on the
GS980EM/11PT switch. The budget is the maximum wattage the switch
has available for the powered devices on its twisted pair ports. The budget
for GS980EM/11PT should be 62W for power supplies that meet the
specifications in “PWR90ADP AC/DC Power Adapter” on page 50.
The procedure assumes you have already started a local management
session on the device. For instructions, refer to “Starting a Local
Management Session” on page 133.
Chapter 9: Powering On the Switch

Chapter 10: Troubleshooting
140
Problem 4: The PoE budget displayed by the SHOW POWER-INLINE
command is 240W below the correct value for the number of PWR300
power supplies connected to the switch. For example, the command
displays a budget of only 480W, instead of 720W, for a switch with three
power supplies, or 240W, instead of 480W, for a switch with two power
supplies.
Solutions: One PWR300 power supply is not working.
Examine the DC OUT/FAULT LEDs on the front panels of the PWR300
power supplies. If an LED is off on a power supply, go to Problem 2. If an
LED is amber on a power supply, go to Problem 3.
If the LEDs are green on all the power supplies, try using the SHOW
SYSTEM ENVIRONMENT command to identify the power supply that is
not providing power to the switch. Then try the following on the identified
power supply:
Verify that the DC wire harness is securely connected to the
connector on the switch and power supply.
Verify that the AC power cable is securely connected to the
connector on the power supply and the AC power source.
Try replacing the DC wire harness.
Try replacing the power supply.
Problem 5: The PoE budget displayed by the SHOW POWER-INLINE
command is below the correct value for the number of PWR300 power
supplies connected to the switch. For example, the switch has three power
supplies, but the command displays a budget of only 680W, instead of
720W.
Solutions: The DC output from one or more of the PWR300 power
supplies is below operating norms.
This is usually caused by a failing or overheating power supply. (DC
outputs decrease as power supplies overheat.) Try the following:
Verify that there is adequate airflow around the power supplies.
Verify that there is adequate distance for ventilation between the
power supplies and between the power supplies and other network
devices.
Examine the DC OUT/FAULT LEDs on the front panels of the PWR300
power supplies. If the LED is amber on a power supply, signaling a fault
condition, replace that unit.

Problem 6: The switch stopped supplying power to one or more powered
devices on ports 1 to 8.
Solutions: The DC output from one or more of the PWR300 power
supplies has fallen below operating norms, causing the switch to deny
power to one or more devices, or a power supply has failed. Perform the
SHOW SYSTEM ENVIRONMENT command and refer to Problems 4
and 5.
PoE++ on
Ports 1 to 8
Problem 1: The GS980EM/10H switch is providing power to some but not
all powered device on ports 1 to 8.
Solutions: Try the following:
Examine the LINK/ACT LED on the port. If it is off, go to “Twisted
Pair Ports 1 to 8” on page 144.
Check the port PoE LEDs. If an LED is flashing amber, the switch
cannot support the device because doing so would exceed its PoE
budget. If this is the case, use the SHOW SYSTEM
ENVIRONMENT command to display the switch’s PoE budget and
compare that value with the total requirements of the PoE devices
in the worksheet in “Planning the Installation” on page 36.
If the powered device is Class 8, confirm that it uses Type 3 wiring
to receive power, by referring to its documentation.
Verify that you are using the appropriate category of twisted-pair
cable. Cable requirements for the switch are listed in “Cable
Requirements” on page 26.

GS980EM Series Installation Guide
143
PoE+ on Ports 1
to 8
Problem 1: The GS980EM/11PT switch is not providing power to any
PoE+ devices on ports 1 to 8.
Solutions: Port 11 might be connected to a Class 4 power source. A
Class 4 power source can provide the switch with enough power to
operate as a switch, but not enough for a PoE budget. If you want to use
port 11 to power the switch and to support powered devices, you must
connect it to a Class 6 or 8 device.
Problem 2: The GS980EM/11PT switch is providing power to some but
not all PoE+ devices on ports 1 to 8.
Solutions: Try the following:
Examine the LINK/ACT LED on the port. If it is off, go to “Twisted
Pair Ports 1 to 8” on page 144.
Check the port’s PoE LED. If the LED is flashing amber, the switch
cannot support the device because doing so would exceed its PoE
budget. If this is the case, use the SHOW SYSTEM
ENVIRONMENT command to display the switch’s PoE budget and
compare that value with the total requirements of the PoE devices
in the worksheet in TBD.
Review the powered device’s documentation to confirm that the
device supports Mode A of the IEEE 802.3at standard and that it
uses pins 1, 2, 3, and 6 on the RJ-45 port to receive power. Refer
to “RJ-45 Twisted Pair Port Pinouts” on page 155.
Check that the device’s power requirements do not exceed 30W by
reviewing the device’s documentation or data sheet.
Verify that you are using the appropriate category of twisted-pair
cable. Cable requirements for the switch are listed in TBD.
Use the management software on the switch to determine whether
PoE is enabled on the port. The default setting for PoE is enabled.
Use the management software on the switch to determine whether
the PoE power setting for the port has been reduced to a value
below the power requirements of the device.
Try connecting the device to a different port on the switch.
Chapter 10: Troubleshooting
144
Twisted Pair Ports 1 to 8
Problem 1: The LINK/ACT LED for a twisted pair port connected to a
network device is off.
Solutions: The port cannot establish a link with a network device. Try the
following:
Verify that the network device connected to the twisted pair port is
powered on and is operating properly.
Try connecting another network device to the twisted pair port with
a different cable. If 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. Refer to “Cable Requirements” on page 26.
Verify that the port is connected to the correct twisted pair cable.
If all the port LEDs are off, the switch might be operating in the low
power mode. To toggle on the LEDs, use the ECOFRIENDLY LED
and NO ECOFRIENDLY LED commands in the command line
interface.
Note
Twisted pair ports may require five to ten seconds to establish links.
GS980EM Series Installation Guide
145
SFP Ports
Problem: The LINK/ACT LED is off for an SFP port with a transceiver that
is connected to an active network device.
Solutions: The transceiver is unable to establish a link to a network
device. Try the following:
Verify that the remote network device is operating properly.
Verify that the fiber optic cable is securely connected to the port on
the transceiver and the remote network device.
Check that the transceiver is fully inserted in the port.
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 cannot 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 (sensitivity) or strong (maximum input power).
