Step 1. Connect the equipment.
This switch is designed for indoor use only. If you want to connect it to a device located
outdoors, the outdoor device must be properly grounded and surge protected, and you
must install an Ethernet surge protector inline between the switch and the outdoor device.
Failure to do so can damage the switch.
WARNING: Before connecting this switch to outdoor cables or devices, see
https://kb.netgear.com/000057103 for safety and warranty information.
Step 2. Connect to power.

PoE Max LED
The maximum PoE (802.3af) power that the switch can deliver to all attached powered
devices (PDs) is 53 Watts (W) total. Ports 1 through 4 can support PoE power with a
maximum power to each port of 15.4W. (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.
Solid amber: Less than 7W of PoE power is available on the switch (the LED is
on).
Blinking amber: The PoE Max LED was active in the previous two minutes (the
LED is blinking).
Off: Sufcient (more than 7W of) PoE power is available on the switch.

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 of 16.2W that the switch permits.
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.
PoE considerations
The switch prioritizes the PoE (802.3af) 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 rst.
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 specication. Many PDs require less power,
allowing all four PoE ports to be active simultaneously.
The following table describes the PoE classes and switch allocations.
Device
Class
Standard Class Description Minimum Power
Allocated to the
Powered Device
Range of Power
Delivered to the
Powered 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
PoE troubleshooting
Here are some tips for correcting PoE problems that might occur:
• Make sure that the PoE Max LED is off. 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 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.
