Or, if the software version specifically requires an upgrade of the bootloader code
as well, follow this general procedure:

When you reset the host system following the upgrade, the boot code forces the
cascade ports to come up in an enabled state. The boot code then communicates
the version and size of the host's runtime image to the slave controllers. If the
slave controller detects a difference from its runtime image, it initiates a
download from the host.
The remote shelf controller runtime code is loaded to the shelf's local flash
memory, but the LIM code is loaded from the host directly to the remote shelf's
RAM.
You do not need to reset each remote shelf separately. The system resets slave
controllers automatically when you use the automatic upgrade procedure.
Manual upgrade via loadslave (optional procedure)
You can choose to upgrade each shelf manually, to slightly reduce the service
outage of an upgrade procedure. The loadslave command loads software to a
remote shelf from the host's flash memory. To upgrade the shelves manually, the
loadslave command must be entered before resetting the host. (After the reset,
system automatically upgrades remote shelves with older software.)
The loadslave command uses the following syntax:
loadslave shelf [image (1=cmb.bin 2=cmb.bin 3=cm.ffs)
For example, the following command loads the operational software from the
host to remote shelf 2:
HOST> loadslave 2 3
The first argument specifies the remote shelf ID, and the second argument
represents the file to load, as shown in the following list:
Number
File name
1 or 2
mrtcmb.bin
3
mrtcm.ffs
