Upgrading a Supervisor Module
You can upgrade supervisor modules by using the hot swap method. The upgrade path for your active supervisor
module can be found in the following table:
Allowed UpgradeActive Supervisor
Supervisor A+Supervisor A
Supervisor B+Supervisor A
Supervisor B+Supervisor B
Step 1 Insert the new supervisor module in the empty slot.
Step 2 Bring up the new supervisor module:
a) If the newly inserted supervisor module becomes stuck in the loader prompt, use the reload module <x> force-dnld
command on the active supervisor module. This action brings up the new supervisor module.
b) If the newly inserted supervisor module has an older BIOS (<5.20), and is unable to boot, you will have to upgrade
the BIOS. Use the flwr tftp|usb<x>://<ip>/img_name1 command, from the newly inserted supervisor module
loader prompt. Then use the reload module <x> force-dnld command from the active supervisor module to bring
up the new supervisor module.
Step 3 Once the new supervisor module has been brought up in ha-stby mode, do a copy r s. Then issue a system switchover.
Installing or Replacing a System Controller Module
The switch can operate with one or two system controller modules that are installed in the chassis. You can
replace one system controller module while there is another one installed in the chassis.
