NETGEAR GS108LP User Manual

Alternative Power Source
Where possible, check if the PD works with another PoE switch, or, where applicable check if the PD
powers on using an external power supply. If the PD does not power on from any of these power
sources, then the problem is likely with the PD.
Cabling
Check that the Ethernet cabling you are using is of good quality. It should be CAT5e or better. To be
certain, try testing with different cabling to that currently in use.
Port Configuration
In the admin page of the switch, ensure that the port connected to the PD is not administratively
disabled. Also, check that the PoE configuration of the port is valid (i.e. that PoE is enabled for the port,
and, set to the right standard and power limit, where applicable). For further information, refer to the
user manual for your switch.
Note: This does not apply to unmanaged switches and certain Web Managed Plus switches.
Firmware Update
It is possible that specific PoE-related problems may have been addressed in a firmware release. Refer
to the product support page for your switch to download the latest firmware and update it. For further
information, refer to the user manual for your switch and firmware release notes.
Note: This does not apply to unmanaged switches.
Reset Configuration
It is possible that a mis-configuration of the switch may cause problems. Reset the switch to factory
default settings. This will erase the current configuration so you should, where necessary, make a
configuration backup before completing this step.
Note: This does not apply to unmanaged switches.
Further Considerations
 If your PoE switch model is GS105PE, then refer to https://kb.netgear.com/25541/GS105PE-PoE-
troubleshooting for guidance specific to this device.
 If you see symptoms where you cannot power more than one PD in a set of adjacent ports, such as
scenarios outlined below, please contact NETGEAR Support. When contacting Support, it may be
beneficial to reference the troubleshooting you have already carried out as described in this article.
o On a switch with greater than 16 ports, a PD on Port 1 powers on but a PD on ports 2, 3 & 4 does
not power on. Similarly, a PD on port 5 powers on but a PD on ports 6, 7 & 8 does not power on.
o On a switch with 16 ports or less, a PD on Port 1 powers on but a PD on Port 2 does not power on.
Similarly, a PD on Port 3 powers on but a PD on Port 4 does not power on.
