1.10.9 Software Upgrade
1.10.9.1 Introduction
To upgrade the system to a new software release, load files can be remotely loaded into FLASH memory and
then individually selected for use at runtime. Along with the user commands described earlier in this manual,
there are comprehensive commands provided to examine the state of the FLASH memory and to load, view,
and remove release files. There are also commands provided to install, query, and activate the software on each
card, at which time the software is booted into RAM memory and executed.
The latest software release files are available from Allied Telesis. For the latest software loads go to
http://www.alliedtelesis.com/support/software/restricted/login.aspx
You should have an account with an email address and password.
The general steps are:
1. If not already done, set up the MGMT/Inband interface and network servers. Refer to Section 1.6.4
2. Do SHOW SYSTEM or SHOW CARD ACTCFC SOFTWARE to see what CFC load is used.
3. Compare current system loads with the latest load’s information.
4. If the loads are the same, no action is required.
5. If the loads are not the latest, contact ATI to obtain them.
1.10.9.2 Software Upgrade Procedure - Overview
A software upgrade involves obtaining new load files. Next, the loads are stored in FLASH on the CM. The
boot status of the new loads is set to TEMPLOAD. The user then executes a restart on the control module.
The user verifies that the new loads are working correctly. The user must commit, then downgrade if neces-
sary.
Commit means that the user chooses to accept the new loads as the new system load files. After setting the
loads as PREFLOAD, the system will boot from these loads until new loads are set as PREFLOAD.
The user can choose to perform a downgrade after a software upgrade has been completed. The user may
revert back to the original load files and database, but any changes made to the new database are lost.
