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
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.
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.
