Diagnosing Problems
By observing system diagnostics and reviewing the
tables in this chapter, you can identify and correct
problems that can occur at system power up.
Power Failures
If the system does not respond when you insert the
power cord, see the troubleshooting suggestions in
Table 14.
Abnormal LED Activity
The system processor contains several status LEDs
that indicate system problems. Also, each module has
status LEDs that alert you to problems on a module or
port. See Table 15 and Table 16 for troubleshooting
suggestions in the event of abnormal LED activity on
the system processor or a module.
CAUTION: To prevent the system processor and
modules from damage by electrostatic discharge
during handling, always wear a wrist strap that makes
good skin contact and is connected to a proper
ground.
