Step 8 Repeat Step 2 through Step 7 for additional BSC pairs in your system.
Upgrading NSC Software
The upgrade process for redundant NSCs is graceful. It does not interrupt established calls, but it can
interrupt calls in the process of being established. When you invoke the process, the MGX 8260
upgrades and restarts the standby NSC. You can then commit or cancel the upgrade. When you commit
the upgrade, the MGX 8260 switches to the standby NSC and then upgrades the other NSC.
Warning Upgrading nonredundant cards interrupts service. Perform nonredundant upgrades
during light traffic periods or during a prearranged maintenance window.
NSC redundancy follows an N:1 design, with one NSC providing redundancy for all remaining NSCs.
If your MGX 8260 includes NSCs, perform the following steps to upgrade NSC Flash and software
images:
Step 1 Upgrade the boot Flash software on each NSC using the following command. Issue the command for
each NSC, replacing the <physicalSlotNumber> with the appropriate number for your configuration.
updatefls <physicalSlotNumber> IMAGE/NSC/nsc_r01.02.05.fls
Step 2 If your system includes NSC redundancy, identify the slot number of the NSC providing redundancy.
Step 3 Enter the following command for the first NSC in your system (excluding the redundant NSC
identified in Step 2). Replace the <logicalSlotNumber> with the appropriate number for your
configuration.
upgd <logicalSlotNumber> nsc_r01.02.05.fw
Answer Y to the “Are you sure?” warning message.
In redundant configurations, the upgd command resets the redundant NSC. The redundant NSC should
now be running the new release of boot Flash and software images.
Step 4 Ensure that the standby/redundant NSC has finished rebooting and is in the standby state.
Step 5 You can now commit or cancel the upgrade.
a. If your MGX 8260 is configured for NSC redundancy, and you wish to cancel the upgrade, enter
the upgdcancel command. You can use this command only if you have not entered the upgdcmit
command. You cannot cancel an upgrade for nonredundant cards.
Note Before you cancel an upgrade with the upgdcancel command, you need to to reset the
previous software on the flash card using the updatefls command.
b. To commit the new software, use the following command. Issue the command for the first NSC as
indicated in Step 3. Replace the <logicalSlotNumber> with the appropriate number for your
configuration.
upgdcmit <logicalSlotNumber>
Warning You must execute either the upgdcmit command in Step 5b. or the upgdcancel command in Step
5a. If you do not execute one of these commands, database corruption occurs.
