Step 4
Verify the settings in the system setup program. For details, refer to the software configuration guide or
user guide that corresponds to the version of software you are running on your system (see the
“Obtaining Documentation and Submitting a Service Request” section on page -iii ).
Did the system complete the boot routine?
Yes . The system configuration information was incorrect. You have fixed the problem.
No . Call your service representative (see the “Obtaining Documentation and Submitting a Service
Request” section on page -iii ).
Checking Connections and Switches
Improperly set switches and controls and loose or improperly connected cables are the most likely source
of problems for the chassis or other external equipment. A quick check of all the switches, controls, and
cable connections can easily solve these problems. (See
Figure 1-2 on page 1-2 for the location of front
panel controls and indicators. See Figure 1-3 on page 1-3 for the location of back panel connections on
the system.)
To check all the connections and switches, follow these steps:
Step 1 Power down the system, including any attached peripherals such as external drives. Disconnect all the
power cables from their electrical outlets.
Step 2
If the system is connected to a power strip (or power distribution unit), turn the power strip off and then
on again.
Is the power strip receiving power?
Yes . Go to Step 5 .
No . Go to Step 3 .
Step 3
Plug the power strip into another electrical outlet.
Is the power strip receiving power?
Yes . The original electrical outlet probably does not function. Use a different electrical outlet.
No . Go to Step 4 .
Step 4
Plug a system that you know works into the electrical outlet.
Does the system receive power?
Yes . The power strip is probably not functioning properly. Use another power strip.
No . Go to Step 5 .
Step 5
Reconnect the system to the electrical outlet or power strip.
Make sure that all connections fit tightly together.
Step 6
Power up the system.
Is the problem resolved?
Yes . The connections were loose. You have fixed the problem.
No . Call your service representative. (See the “Obtaining Documentation and Submitting a Service
Request” section on page -iii .)
