PoE Max LED

The maximum PoE power that the GS308P switch can deliver to all attached powered devices
(PDs) is 53 Watts total, with a maximum power to each port of 15.4 Watts. (For more
information, see PoE Considerations.)

The PoE Max LED indicates the status of the PoE power that the switch can deliver to all
attached PDs.

PoE Considerations

The switch prioritizes the power that it supplies in ascending port order
(from Port 1 to port 4), up to its total power budget (53 Watts). If the
power requirements for the attached powered devices (PDs) exceed the
total power budget of the switch, the PD on the highest numbered port is
disabled to ensure that the PDs that are connected to the higher priority,
lower numbered ports are supported first.

Just because a PD is listed as an 802.3af PoE powered device does
not necessarily mean that it requires the maximum power limit of the
specification. Many PDs require less power, allowing all four PoE ports to be
active simultaneously.

The following table describes the PoE classes and switch allocations.

right port LED lights solid amber, a PoE fault occurred and PoE halted
because of one of the conditions that are listed in the following table.

PoE Fault Condition Possible Solution

A PoE-related short circuit occurred on the port.

The PoE power demand of the PD exceeded the
maximum level of 16.2W that the switch permits.

The PoE current on the port exceeded the
classification limit of the PD.

The PoE voltage of the port is outside the range
that the switch permits.

The problem is most likely with the
attached PD. Check the condition
of the PD or restart the PD by
disconnecting and reconnecting the PD.

Restart the switch to see if the
condition resolves itself.

PoE Troubleshooting

Here are some tips for correcting PoE problems that might occur:

• Make sure that the PoE Max LED is o. If the PoE Max LED is
solid amber, disconnect one or more PoE devices to prevent PoE
oversubscription. Start by disconnecting the device from the highest
numbered port.

• Make sure that the Ethernet cables are plugged in correctly. For
each powered device (PD) that is connected to the switch, the
corresponding right port LED on the switch lights solid green. If the
