Step 2: Configuring the Nortel Networks WLAN - Access Point Before Installation
- Make sure that a DHCP server is configured in the Nortel Networks WLAN - Wireless
Security Switch for both the Management Interface and AP-Manager Interface using the
CLI, Web Browser, or WLAN Control System interface, and that the DHCP server is
operating correctly.
- Once the AP finds the Nortel Networks WLAN - Wireless Security Switch, it attempts to
download the new Operating System code if the AP code version differs from the Nortel
Networks WLAN - Wireless Security Switch code version. While this is happening, the
LEDs on the top of the AP blink on and off together.
4. Once the Operating System code download is successful, the AP reboots. The GREEN LED turns
on and the two YELLOW/AMBER/ORANGE LEDs indicate the states of the 802.11a and 802.11b/
g networks. If any part of the network is disabled in the Nortel Networks WLAN - Wireless
Security Switch, the corresponding YELLOW/AMBER/ORANGE LED remains off.
- Note that the Red LED can light for a short period (10-20 seconds) when the AP
reboots. If the RED LED comes on AND STAYS ON for more than a minute, disconnect
the AP and call Nortel Networks Technical Support.
- From the CLI, Web Browser or WLAN Control System interface, configure the AP with its
Primary Nortel Networks WLAN - Wireless Security Switch name as described in the
Nortel Networks Product Documentation.
- If required, use the CLI, Web Browser or WLAN Control System interface to customize
the AP-specific 802.11a, 802.11b and 802.11g network settings. Once again, the two
YELLOW/AMBER/ORANGE LEDs indicate the states of the 802.11a and 802.11b/g
networks. If any part of the network is disabled, the corresponding YELLOW/AMBER/
ORANGE LED remains off.
5. If everything works (the GREEN LED is on and the RED LED is off), disconnect the AP and take
it to its final destination and install it as described in this document. If your Nortel Networks
WLAN - Access Point fails this visual test, refer to RMA Procedures in the Nortel Networks
Product Documentation to return your Nortel Networks WLAN - Access Points.
Note: When you are installing a Layer 3 Nortel Networks WLAN - Access Point on a different
subnet than the Nortel Networks WLAN - Wireless Security Switch, 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 Nortel Networks WLAN - Wireless Security Switch. Also make sure that the
route back to the Nortel Networks WLAN - Wireless Security Switch has destination UDP ports
12222 and 12223 open for LWAPP communications. Ensure the route back to the Primary
Nortel Networks WLAN - Wireless Security Switch allows IP packet fragments. Finally, make
sure that if address translation is used, that the Access Point and the Nortel Networks WLAN -
Wireless Security Switch have a static 1-to-1 NAT to an outside address. (Port Address Trans-
lation is not supported.)
6. 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 4. If no LEDs are on, the AP is most likely not
receiving power. If the LEDs all the LEDs blink sequentially back and forth for more than five
minutes, the AP is unable to find its Primary Nortel Networks WLAN - Wireless Security Switch.
Check the connection between the AP and the Nortel Networks WLAN - Wireless Security
Switch, and make sure the AP and the Nortel Networks WLAN - Wireless Security Switch are
either on the same subnet or that the AP has a route back to its Primary Nortel Networks WLAN
- Wireless Security Switch. Also, if the Nortel Networks WLAN - Access Point is not on the same
subnet as the Nortel Networks WLAN - Wireless Security Switch, make sure there is a DHCP
server on the same subnet as the Nortel Networks WLAN - Access Point.
After you have prepared all Nortel Networks WLAN - Access Points, reconfigure the Nortel Networks
WLAN - Wireless Security Switch so it is not the Master. A Master Nortel Networks WLAN - Wireless
Security Switch should only be used for configuring Nortel Networks WLAN - Access Points and not in a
working network.
