22 Alternate Preparing a Version 2.2 WLAN — Access Port (223x)216394-B Rev 004. Take the WLAN — Access Port (223x) out of the box and plug it into the network so that it can request an IPaddress from the DHCP server.5. Apply power to the WLAN — Access Port (223x):- Use 802.3af-compatible Power Over Ethernet (PoE) from a Nortel Networks PoE equippedSwitches such as the BayStack 460, or from an orderable inline power injector. If you do not havePoE available, use an orderable external AC-to-48 VDC Power Supply plugged into the side of theWLAN — Access Port (223x).- After powering up the WLAN — Access Port (223x), the RED Alarm LED comes on for a shortperiod (about 15-20 seconds) and then all the LEDs blink sequentially back and forth, indicating thatthe WLAN — Access Port (223x) is trying to find a WLAN — Security Switch (2270) to connect to.This can continue for up to five minutes. If the WLAN — Access Port (223x) remains in this modefor more than five minutes, the WLAN — Access Port (223x) is unable to find the Master WLAN— Security Switch (2270). Check the connection between the WLAN — Access Port (223x) and theWLAN — Security Switch (2270) and ensure the WLAN — Access Port (223x) and the WLAN —Security Switch (2270) are on the same subnet.- If the power light does not come on, check the power (it can be powered either with Power overEthernet or a from an orderable WLAN — Access Port (223x) External Power Supply.6. The WLAN — Access Port (223x) or WLAN — Access Port (223x) requests an IP address from the DHCPserver, and the DHCP server returns an IP address for the WLAN — Access Port (223x) or WLAN — AccessPort (223x), and also returns the of the configuring WLAN — Security Switch(2270).Once the WLAN — Access Port (223x) or WLAN — Access Port (223x) finds the configuring WLAN —Security Switch (2270), it attempts to download the new Operating System code if the WLAN — Access Port(223x) code version differs from the configuring WLAN — Security Switch (2270) code version. While this ishappening, the LEDs on the top of the WLAN — Access Port (223x) or WLAN — Access Port (223x) blinkon and off together.7. Once the Operating System code download is successful, the WLAN — Access Port (223x) or WLAN —Access Port (223x) reboots. The GREEN LED turns on and the two YELLOW LEDs indicate the states of the802.11a and 802.11b/g networks. If any part of the network is disabled in the configuring WLAN — SecuritySwitch (2270), the corresponding YELLOW LED remains off.- Note that the Red LED can light for a short period (10-20 seconds) when the WLAN — Access Port(223x) or WLAN — Access Port (223x) reboots. If the RED LED comes on AND STAYS ON formore than a minute, disconnect the WLAN — Access Port (223x) or WLAN — Access Port (223x)and call Nortel Technical Support.- From the CLI, Web Browser or WLAN — Management System interface, configure the WLAN —Access Port (223x) with its Primary, Secondary and Tertiary WLAN — Security Switch (2270)names (any of which can be the name of the configuring WLAN — Security Switch (2270)) asdescribed in the Nortel Product Guide 320298-A.- If required, use the CLI, Web Browser or WLAN — Management System interface to customize theWLAN — Access Port (223x) -specific 802.11a, 802.11b and 802.11g network settings. Once again,Note: When you are installing a WLAN — Access Port (223x) or a WLAN — Access Port (2230/2231), a DHCP server must be accessible by the WLAN — Access Port (223x) or a WLAN —Access Port (2230/2231).
