[USR-TC] Changing IP address on NMC

I am using the USR HiperArc (with NMC) V4.1.59 and would like to know if it is possible (and the command) to change the ip address of the NMC. I can telnet to the chassis, but I do not see any command to change the NMC settings. Anybody have any ideas? If more info is needed, please let me know. Thanks Jeff
