The system software is organized in two files: an expander file

(lpexpand) and a compressed image file (lp2500c). The expander file

is a utility that expands the compressed image and moves it from flash

memory into random access memory on the system.

To install system software, you complete these four tasks:

Retrieve the expander file: lpexpand

Retrieve the compressed image: lp2500c

Reboot the system

Retrieve the compressed image again: lp2500c

Detailed instructions for each task are provided next.

To load the expander file onto the CoreBuilder 2500 system, follow these

steps:

1 To ensure that no other administrative sessions can occur during the

update process, lock the Administration Console:

a From the top level of the Administration Console, enter:

system consoleLock

b At the prompt, enter: on

If you completed step 1 in "Installing the Diagnostic Software" earlier in

these release notes, the consoleLock is already set to on.

CAUTION: If another user logs into the system using telnet while a

software update is taking place, the software images that are stored in

flash memory may become corrupted.
