Replacing The Scc-Sm; Reference - Nortel CVX 1800 Hardware Installation Manual

Replacing the SCC-SM

In a redundant configuration, when you remove the primary SCC-SM, the
secondary SCC-SM automatically copies the system software and configuration
files from its flash memory card. Before removing the primary SCC-SM, ensure
that the secondary SCC-SM flash memory cards are in the PCMCIA slots.
If you have only one SCC-SM (a non-redundant configuration), you will need to
shut down the CVX switch to replace the SCC-SM.

Reference

See the manual CVX 1800 Multi-Service Access Switch Configuration Guide for
information about editing and managing configuration files.

Warning: You must use software Release 5.0 or later when using an
Optical SCC-II-SM. Use of older versions will corrupt the SCC-SM,
requiring the return of the module to Nortel for reprogramming. Do not
copy earlier versions of software to a flash memory card used in an
Optical SCC-II-SM.
Warning: When you remove the primary SCC-SM, a system reset
occurs. This disconnects all calls that are in progress and temporarily
suspends system services until the secondary SCC-SM goes online.
