Cisco WAP121 Panduan Memulai Cepat
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.
