Upgrading SCC Software
The upgrade process for redundant SCCs is graceful. It does not interrupt established calls, but it can
interrupt calls in the process of being established. When you invoke the upgrade process, the MGX 8260
upgrades and restarts the standby SCC. You can then commit or cancel the upgrade. When you commit
the software, the MGX 8260 switches to the standby SCC and then upgrades the other SCC.
Warning Upgrading nonredundant cards interrupts service. Perform nonredundant upgrades
during light traffic periods or during a prearranged maintenance window.
