Chapter 6: Troubleshooting
Power Over Ethernet
106
Problem: The AT-IE200-6FP or AT-IE200-6GP Switch is not providing
power to a PoE or PoE+ device.
Solutions: Try the following:
Check that the device's power requirements do not exceed those
listed in Table 2 on page 28. 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 Table 3 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.
Refer to the device's documentation to verify that it supports
Alternative A as the power delivery method on the Ethernet
cabling. The switch cannot support legacy PoE devices that only
support Alternative B. For more information, refer to "PoE Wiring"
on page 30.
