After you have performed an external visual inspection as described in the pre-
vious section, you should boot the system and, while the boot routine is
running, observe the system for any indications of problems.
NOTES: Most of the steps in this procedure require observation of system
functions and indications, some of which can occur simultaneously. It may be
necessary to reboot the system several times to complete all of these steps.
To perform the following procedure, you need a Dell Diagnostics Diskette cre-
ated from the Dell Server Assistant CD. If such a diskette is not available, you
can create it as described in “Create Diskettes” in Chapter 2 of the User’s
Guide. If a separate diagnostics diskette is included with the system, you may
need to use that diskette.
To observe problem indications during the boot routine, follow these steps:
1. If the system is off, turn on all peripherals and the computer. Insert the
Dell
Diagnostics Diskette
into the diskette drive and reboot the system.
2. Check each power supply fan.
