Replacing a WLAN IP Telephony Manager 2245
Failed master WLAN IP Telephony Manager 2245
If the master WLAN IP Telephony Manager 2245 fails, no telephone calls can
be made or received on that subnet. To quickly restore functionality to the
wireless telephone network, Nortel recommends changing the configuration
of a slave WLAN IP Telephony Manager 2245 to the configuration of the
master. Then reset all the other slave WLAN IP Telephony Managers 2245.
When they come back up, the slaves recognize the reconfigured slave as
the new master.
Then follow the steps in Procedure 10 "Replacing a WLAN IP Telephony
Manager 2245" (page 112) to replace the failed WLAN IP Telephony
Manager 2245.
