Poe++ On Ports 1 To 8 - Allied Telesis x320 Series Installation Manual

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.

Problem 2: The x320-10GH switch stopped providing PoE power to
devices on Low or High priority ports.
Solutions: One of the PWR300 power supplies might have lost power of
failed. Refer to Problems 2 and 3 in "PWR300 Power Supply" on
page 108:
Problem 3: A pre-802.3bt-compliant device is not working with the switch.
Solutions: Use the POWER-INLINE ALLOW-PRE-BT command in the
Global Configuration mode of the command line interface of the
AlliedWare Plus management software.
Examine the LINK/ACT LED on the port. If it is off, go to "Twisted
Pair Ports 1 to 8" on page 112.
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 31.
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 21.
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.
