Upgrading 882s over a network

Upgrade options and procedures

Backing up the current files on the file server

140 Chapter 4 Networking 882s
An upgrade to a network of 882s can involve a new system and firmware file ("vxWorks"),
a new gateware file, and new library resource files. In some cases you may be upgrading
only the firmware or only the gateware, but not both. In other cases, the upgrade may
involve only new images or formats. The procedures you follow for an upgrade will
therefore depend on what you are upgrading.
This section provides procedures for upgrading 882s over a LAN. The procedures for
upgrading a single 882 that is not connected to a LAN are provided in
generator locally" on page 97.
The recommended procedure for upgrading is to upgrade the file server and the flash
memory of each 882. Upgrading the PC card is optional, depending on how your site uses
the PC card. For example, you may decide to leave the current files on the PC card so you
can return to a known operational state should the upgrade fail.
To begin an upgrade, you must either have a CD-ROM containing the new files, or
download the files from the Quantum Data Web site. You will copy the new files to your file
server PC which must be connected to the LAN through the Ethernet cable.
Overview of upgrade procedures
The following are the high-level steps for performing a complete upgrade (system and
firmware file, gateware, and library resource files) to 882s over a network. Detailed
instructions for each step are provided in the sections that follow.
1. Back up the current file server system and firmware file, gateware, and library files.
2. Copy the new 882 system and firmware file, gateware, and resource files onto the file
server PC.
3. Remove the system and firmware file, gateware, and library resource files from each
882's flash memory.
4. Copy the new system and firmware file, gateware, and library resource files from the
file server PC to each 882's flash memory.
5. Reboot all 882s.
Backing up the current files ensures that you can return to a known operational state
should the upgrade fail.
