Checking Connections and Switches
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 1-1 for the location of front panel controls
and indicators. See Figure 1-3 for the location of back panel connectors on
the system.)
To check all the connections and switches, follow these steps:
Step 1
Power down the system. 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.
If the power strip is receiving power go to Step 5 .
If the power strip is not receiving power go to Step 3 .
Step 3
Plug the power strip into another electrical outlet.
If the power strip is receiving power, the original electrical outlet probably does
not function. Use a different electrical outlet.
If the power strip is not receiving power go to Step 4 .
Step 4
Plug a system that you know works into the electrical outlet.
If the system receives power, the power strip is probably not functioning properly.
Use another power strip.
If the system does not receive power, 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.
If the problem is resolved, the connections were loose. You have fixed the
problem.
