sources.
4. Inspect connections to any attached devices including network cables, keyboard, monitor, mouse (if used), or
keyboard/video/mouse (KVM) switch (if used), as well as any devices attached to the serial port.

Observing the Boot Routine
After you have performed an external visual inspection, boot the system and, while the boot routine is running, observe the
system for any indications of problems.
NOTE:
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.
NOTE:
You can run the system diagnostics from a set of diskettes you create by downloading the system diagnostics
from the Dell | Support website at support.dell.com.
To observe problem indications during the boot routine, perform the following steps:
1. If the system is off, turn on all peripherals and the system.
2. Check the power-supply indicators.
Is the red fault indicator lit?
Yes. Troubleshoot the system power supply (see your Installation and Troubleshooting Guide).
No. Proceed to step 3.
3. Watch the <Num Lock>, <Caps Lock>, and <Scroll Lock> indicators on the upper-right corner of the keyboard. After
all three indicators flash momentarily, and following a long pause (approximately 30 seconds), the <Num Lock>
indicator should light up and remain on (unless the Num Lock option is set to off in the System Setup program).
Do these indicators flash on and off within approximately 10 seconds after the boot routine starts?
Yes. Proceed to step 4.
No. Replace the keyboard with a known working keyboard. If the problem persist, troubleshoot the system power
supply. If the troubleshooting procedure indicates that the system power supply is operational, troubleshoot the
memory.
