Alternate Preparing a Version 2.0 Nortel Networks WLAN - Access Port (2230/2231)
Note:
When you are installing a Layer 3 Nortel Networks WLAN - Access Port (2230/2231) on a different subnet
than the WLAN Security Switch (2270), MAKE SURE that a DHCP server is available on the subnet where you will
be installing the AP, and that the subnet has a route back to the Primary WLAN Security Switch (2270). Also make
sure that the route back to the Nortel Networks WLAN - Security Switch (2270) has destination UDP ports 12222 and
12223 open for LWAPP communications. Ensure the route back to the Primary WLAN Security Switch (2270) allows
IP packet fragments. Finally, make sure that if address translation is used, that the Access Port (2230/2231) and the
WLAN Security Switch (2270) have a static 1-to-1 NAT to an outside address. (Port Address Translation is not
supported.)

When you have installed and powered up the AP in its final destination, verify that the LEDs are in the same state they
were in at the end of Step 7. If no LEDs are on, the AP is most likely not receiving power. If all the LEDs blink sequen-
tially back and forth for more than five minutes, the AP is unable to find its Primary WLAN Security Switch (2270).
Check the connection between the AP and the WLAN Security Switch (2270), and make sure the AP and the WLAN
Security Switch (2270) are either on the same subnet or that the AP has a route back to its Primary WLAN Security
Switch (2270). Also, if the Nortel Networks WLAN - Access Port (2230/2231) is not on the same subnet as the WLAN
Security Switch (2270), make sure that a DHCP server is accessible on the same subnet as the Nortel Networks WLAN -
Access Port (2230/2231).
