Problem 5: The SHOW STACK command is not displaying all the
switches in the stack.
Solutions: If you are using 10Gbps ports for the stack trunk, try the
following:
 Verify that the stacking ports are properly cabled. Refer to
Chapter 10, “Cabling the Networking Ports” on page 231.
 If you are using SFP+ transceivers for the stack trunk, verify that
they are fully inserted into the transceiver ports.
 If you are using SPI0TW direct connect twinax cables, verify that
they are from Allied Telesis. The trunk will not work with cables
from other network equipment manufacturers.
 Verify that VCStack is activated on the switches. For instructions,
refer to Chapter 7, “Building the Trunk with the Default 10Gbps
Stacking Ports” on page 141.
Problem 6: The GS980MX/10HSm, GS980MX/18HSm, GS980MX/
28PSm or GS980MX/52PSm switch is not providing power to a PoE
device.
Solutions: Try the following:
 Check the port’s PoE LED. If the LED is flashing amber, the switch
has reached its maximum power budget and cannot support any
additional PoE devices.
 Review the powered device's documentation to verify that it is
compatible with the switch. Refer to “Powered Device Classes” on
page 45 and“Wiring Implementation” on page 47.
 Use the SHOW SYSTEM ENVIRONMENT command to confirm
that both power supplies are operating normally.
 Use the management software to determine whether the switch
has reached its maximum power budget and cannot support any
further powered devices. The maximum power budget is:
– GS980MX/10HSm: 500W with one power supply
– GS980MX/18HSm: 720W with one power supply
– GS980MX/28PSm: 370W with one power supply
– GS980MX/52PSm: 370W with one power supply
 Verify that you are using the appropriate category of twisted-pair
cable by referring to “Cable Requirements” on page 34.
 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.
