Upgrading generators over a network
An upgrade to a network of generators 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 generators over a LAN. The procedures
for upgrading a single generator that is not connected to a LAN are provided in “
Upgrade options and procedures
The recommended procedure for upgrading is to upgrade the file server and the flash
memory of each generator. 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 generators 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 generator 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
generator’s flash memory.
4. Copy the new system and firmware file, gateware, and library resource files from the
file server PC to each generator’s flash memory.
5. Reboot all generators.
Backing up the current files on the file server
Backing up the current files ensures that you can return to a known operational state
should the upgrade fail.
