PoE considerations
The PoE and PoE+ power supplied by the switch is prioritized in ascending port
order: Ports 1–4 support PoE and PoE+ with a total power budget of 63W for the
GS305EP and 120W for the GS305EPP.
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 make sure that the PDs connected to the higher-priority, lower-
numbered ports are supported rst.
A PD listed as an 802.3at PoE powered device does not necessarily require
the maximum power limit of the specication. Many PDs require less power,
potentially allowing more PoE ports to be active simultaneously.
The following table shows the standard power ranges calculated with the
maximum cable length of 328 feet (100 meters).
Device
Class
Standard Class Description Power
Reserved by
the Device
Power
Delivered to
the Device
0 PoE and PoE+ Default power (full) 0.44W 0.44W–12.95W
1 PoE and PoE+ Very low power 4.0W 0.44W–3.84W
2 PoE and PoE+ Low power 7.0W 3.84W–6.49W
3 PoE and PoE+ Mid power 15.4W 6.49W–12.95W
4 PoE+ only High power 30.0W 12.95W–25.5W
If a device receives insufcient PoE power from the switch, consider using a
shorter cable.
PoE troubleshooting
Here are some tips for correcting PoE problems that might occur:
• If the PoE Max LED is solid yellow, disconnect one or more PoE devices to
prevent PoE oversubscription.
• For each powered device (PD) that is connected to the switch, the associated
PoE LED on the switch lights solid green. If the PoE LED lights solid yellow, a
PoE fault occurred and PoE halted because of one of the conditions listed in
the following table.
PoE Fault Condition Possible Solution
A PoE-related short circuit occurred on the port.
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.
The PoE power demand of the PD exceeded the maximum
level that the switch permits. The maximum level is 15.4W for
a PoE connection and 30W for a PoE+ connection.
The PoE current on the port exceeded the classication limit
of the PD.
The PoE voltage of the port is outside the range that the
switch permits
Restart the switch to see if the
condition resolves itself.
Mount the switch on a wall
We recommend that you use the wall-mount screws that came with the switch.
1. Locate the two mounting holes on the bottom panel of the switch.
2. Mark and drill two mounting holes in the wall where you want to mount the
switch.
The two mounting holes must be 2.95 in. (75 mm) apart, center-to-center.
3. Insert the supplied anchors into the wall and tighten the screws with a No. 2
Phillips screwdriver.
Leave about 0.125 in. (4 mm) of each screw protruding from the wall so that
you can insert the screws into the holes on the bottom panel.
Note: The screws are 6.5 mm in diameter, 16 mm in length.
