You can use the LEDs for troubleshooting. For more information, see the following
sections:
•
Power LED remains off on page 115
•
2.4 GHz WLAN LED, 5 GHz WLAN LED, or both WLAN LEDs are off on page 116
•
LAN LED is off in a setup with a power adapter on page 116
Power LED remains off
Note: If you do not use a power adapter, the AP requires PoE+ (802.3at) power. Do
not use a PoE (803.2.af) switch because the provided power is insufficient.
PoE+ connection: If you use a PoE+ connection and the Power LED and other LEDs
remain off when you connect the Ethernet cable to a PoE+ switch, do the following:
•
Make sure that the LEDs are not disabled (see Control the LEDs on page 88).
•
Make sure that the Ethernet cable between the AP and the PoE+ switch is correctly
connected at both ends.
•
Make sure that the other end of the Ethernet cable is plugged into a PoE+ port, not
a regular (non-PoE+) port.
•
Make sure that the switch is actually receiving power.
•
Make sure that the PoE power budget of the PoE+ switch is not oversubscribed so
that the switch is capable of delivering PoE+ power to the AP. Most PoE switches
have LEDs that indicate when they are providing PoE+ power on a port and an LED
that indicates PoE oversubscription.
Power adapter: If you use a power adapter and the Power LED and other LEDs remain
off when you provide power to the AP, do the following:
•
Make sure that the LEDs are not disabled (see Control the LEDs on page 88).
•
Make sure that the power adapter is correctly connected to the AP, and that the
power adapter is correctly connected to a functioning power outlet. If it is plugged
into a power strip, make sure that the power strip is turned on. If it is plugged directly
into the wall, verify that the outlet is not switched off.
•
Make sure that you are using the correct NETGEAR power adapter for this product.
That is, do not use the power adapter for another NETGEAR product or a third-party
power adapter.
