Power Over Ethernet
Problem: The switch sourcing PoE is not providing power to the connected
PoE powered devices
Solutions: Try the following:
Check that the device’s power requirements do not exceed those
listed in Table 1 on page 29. The power requirements should be
included in the device’s documentation or data sheet.
Start a local or remote management session on the switch and
enter the SHOW POWER-INLINE command. Subtract the Actual
Power Consumption value from the Power Allocated value to
determine the amount of unused power. The switch cannot support
the powered device if this value is less than the device’s power
requirements.
Verify that you are using the appropriate category of twisted-pair
cable by referring to “Cabling Requirements for PoE Devices” on
page 29.
Try replacing the twisted pair cable.
Use the management software on the switch to determine whether
PoE/PoE+ is enabled on the port. The default setting is enabled.
Use the SHOW POWER-INLINE command to determine whether
the PoE power setting for the port was reduced to a value below
the power requirements of the device.
Try connecting the device to a different port on the switch.
