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
9, "Cabling the Networking Ports" on page 203.
If you are using SFP+ transceivers for the stack trunk, verify that
they are fully inserted into the transceiver ports.
If you are using AT-SP10TW 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 the VCStack is activated on the switches. For
instructions refer to "Verifying the Stack" on page 153.
Problem 6: The x530L-10GHXm, x530L-18GHXm, x530L-28GPX or
x530L-52GPX switch is not providing power to a PoE device.
Solutions: Try the following:
Review the powered device's documentation to verify that it is
compatible with the switch. Refer to "Powered Device Classes" on
page 43 and "Wiring Implementation" on page 45.
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, and so cannot support any
further powered devices.
Verify that you are using the appropriate category of twisted-pair
cable.
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.
