3.3.2 AlphaServer 1000A System
Once the AlphaServer 1000A system power is turned on, the screen on the IP Platform
console displays test codes and initialization messages. When the startup procedure is
complete, the following occurs:
•
The IP Platform console terminal emulation window displays the SRM console prompt
(>>>).
•
The operator control panel on the front of the AlphaServer 1000A system displays the
message "Model 5/500."
Boot the Tru64 UNIX system by typing boot at the console prompt. For duplex systems, type
boot at each processor window. The AlphaServer 1000A system has booted successfully when
the Tru64 UNIX prompt (#) appears.
Refer to the DIGITAL UNIX Installation Guide for installation instructions on booting a
Tru64 UNIX system.
Refer to the AlphaServer 1000A Rackmount Owner's Guide, for additional information on the
