Upgrading, Restoring, and Backing
Up System Software and Firmware
Overview of This Chapter
This chapter describes how to upgrade, back up, and restore the Access
Concentrator system software and firmware.
Note:
If the system software release to which you are upgrading
requires a firmware update, you need to perform the remote
software upgrade procedure, or arrange for an in-factory or
on-site upgrade by Lucent Technologies, Inc. personnel. The
Release Note for the system software version to which you are
upgrading identifies any affected modules. Your Lucent
Technologies customer engineer or a NetworkCare
SM
representative can provide you with details about the return
materials authorization (RMA) process or, depending on the type
of service agreement you have, the on-site upgrade procedure.
For information on these services, contact Lucent Technologies
NetworkCare (see "Technical Support" in Chapter 1, "Getting
