1. Shut down the operating system and issue the console commands show
configuration, show device, and show <envar> to show the system
configuration and environment variables. Keep a hard copy of the output for
reference. Note any new options being added for this upgrade.
2. If the power requirements of the upgraded system have not already been
calculated, do so now to determine the number of power regulators required. See
the AlphaServer 8400 Power Configuration Table in the Digital Systems and
Options Catalog.
3. The 8400 in the upgrade kit has one H7263 regulator. If another is needed to
meet the power requirements of the upgraded system, make sure it is added
before proceeding with the upgrade.
4. Since individual configurations vary, the 8400 in the upgrade kit is supplied
with only one DWLPB–AA and one BA661-AA StorageWorks shelf. Make
sure that you have sufficient plug-in units, shelves, and the proper length I/O
cables to meet your needs before proceeding with the upgrade.
