Possible Cause of Failure

No Power

• Power up the switch and your computer if they are turned off.

• If your access point is using PoE, make sure your PoE switch is powered

on and the lights indicate that you have a link. See

Hardware Installation" on page

• Verify that the power button is on; only applicable if you are not using

PoE.

• Verify that the devices on your network are not plugged into a

switchable outlet.

Bad Ethernet Connection

• Check the state of the indicator lights. See

Installation" on page

• Check the connectors of the Ethernet cable to ensure they are firmly

plugged into the switch and your computer.

• Verify the connected switch has auto-negotiation enabled. The access

point and the switch need the same negotiation parameters set.

contact system support; see

Incorrect IP Address

The most likely cause of connectivity failure is an incorrect IP address. The

Web browser may be pointed to the wrong IP address, or your computer

may be configured with an IP address that is not in the same subnet as the

device.

Because the factory default IP address configuration is DHCP, make sure

that your DHCP server is running and can be reached. You may need to

disconnect and reconnect the devices for them to discover their new IP

addresses from the DHCP server. You can then query the DHCP server for

the new IP address. See

Configuration" on page 7

address.

If the wireless access points do not receive a DHCP response (there is no

DHCP server on your network) after 60 seconds, the access points will

fallback to the following default static IP address: 192. 1 68. 1 .245 and a

default mask of 255.255.255.0. To reach that IP address, be sure that your

computer is on the 192. 1 68. 1 .xxx network.
