Chapter 3 Card Management
Upgrading Software Images
To upgrade SCC and software images, perform the following steps:
Step 1 Upgrade the boot Flash software on each SCC using the following command. Issue the command for
each SCC, replacing the <physicalSlotNumber> with the appropriate number for your configuration.
updatefls <physicalSlotNumber> IMAGE/SCC/scc_r01.02.05.fls
Step 2 Ensure that the standby SCC is in the standby state.
Step 3 Upgrade the software image on the active SCC using the following command:
upgd 9 scc_r01.02.05.fw
Note Enter a 9 even if card 10 is active. This parameter refers to logical card 9. The active SCC
is always logical card 9 regardless of its physical slot location.
In redundant configurations, the upgd command resets the standby SCC. Wait until the standby SCC
reboots and its console session shows a standby state. At that point, the standby SCC will be running
the new release of boot Flash and software images.
Step 4 You can now commit or cancel the upgrade.
a. For redundant SCCs, if you wish to cancel the upgrade, enter the upgdcancel command. 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, enter the following command:
upgdcmit 9
On redundant systems, the upgdcmit command switches over the two SCCs. The SCC that was
standby is placed into active state with its newly upgraded database and software image, and the
previously active SCC resets and boots up to standby state.
Warning You must execute either the upgdcmit command in Step 4b. or the upgdcancel command in Step
4a. If you do not execute one of these commands, database corruption will occur.
Step 5 Ensure that the previously active SCC has completed booting and is in standby state.
Step 6 On redundant systems, force a switchback to the primary card using the swcd command:
swcd 9
Upgrading BSC Software
The upgrade process for redundant BSCs 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 BSC. You can then commit or cancel the upgrade. When you commit
the upgrade, the MGX 8260 switches to the standby BSC and then upgrades the other BSC.
