Physical Inspection Checklist
79
If the behavior of your system is operational, marginal, or faulty, first do a
physical inspection using the checklist below. If all of the connections seem
solid, go on to the section “Using the System Controller” and try to isolate
the problem. If the problem persists, run the diagnostic tests from the System
Maintenance menu or PROM Monitor. See the
IRIX Advanced Site and Server
Administration Guide for more information about diagnostic tests.
If this does not help, contact your system administrator or service provider.
Physical Inspection Checklist
Check every item on this list:
• The console terminal and main unit power switches are turned on.
• The circuit breaker next to the main power cord is not tripped.
• The fans are running and the fan inlets/outlets are not blocked.
• The System Controller LCD screen may display fault messages or
warnings.
Before you continue, shut down the system and turn off the power.
Check all of the following cable connections:
• The system console terminal power cable is securely connected to the
terminal at one end and the power source at the other end.
• The Challenge deskside server power cable is securely connected to the
main unit at one end and plugged into the proper AC outlet at the other
end.
• The Ethernet cable is connected to the 15-pin connector port labeled
Ethernet (and secured with the slide latch).
• Serial port cables are plugged in securely to their corresponding
connectors.
• All cable routing is safe from foot traffic.
If you find any problems with hardware connections, have them corrected
and turn on the power to the main unit. Use the System Controller to
determine if internal system problems exist.
