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 1.53 in. (38.9 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: GS305PP screws are 4.2 mm in diameter, 25 mm in length.

Do not use this device outdoors. The PoE source is intended for intra building
connection only.
PoE considerations
The PoE and PoE+ power supplied by the switch is prioritized in ascending port
order (from port 1 to port 4), with a total power budget of 55.5 watts for the
GS305P, and 83W for the GS305PP switch. 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 that
are connected to the higher-priority, lower-numbered ports are supported rst.
Just because a PD is listed as an 802.3at PoE powered device does not
necessarily mean that it requires the maximum power limit of the specication.
Many PDs require less power, potentially allowing all four PoE ports to be active
simultaneously.
You can override the detected device class and specify the power allocation
for the device connected to each port. The following table shows the standard
power ranges with no overrides applied, and 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) 15.4W 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 insufcient PoE power from the switch, consider attaching a
shorter cable.
PoE Troubleshooting
Here are some tips for correcting PoE problems that might occur:
• 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.
• For each powered device (PD) that is connected to the switch, the associated
right port LED on the switch lights solid green. If the right port LED lights
solid amber, 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 15.4 for a PoE connection or
30W for a PoE+ connection
The PoE current on the port exceeded the
classication 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.
