Chapter 4 Troubleshooting the AVS 3120 Hardware
Checking Connections
4.Did the AVS 3120 complete the boot routine?
–Yes. The AVS 3120 configuration information was correct.
–No. Call your service representative. Refer to the “Obtaining Technical Assistance” section on page xvii.
Checking Connections
Loose, incorrect, or improperly connected cables are the most likely source of problems for the
AVS 3120 or other external equipment. A quick check of all cable connections can solve most problems. Refer to Chapter 1, “Product Overview,” for the location of the front panel indicators and for the location of back panel indicators, connections, and controls on the AVS 3120.
To check all the connections, follow these steps:
1.Power down the AVS 3120. Disconnect all power cables from their electrical outlets.
2.If the AVS 3120 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.
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.
4.Connect a known working AVS 3120 directly to the electrical outlet. Does the AVS 3120 receive power?
–Yes. The power strip is probably not functioning properly. Use another power strip.
–No. Go to step 5.
5.Reconnect the AVS 3120 to the electrical outlet or power strip.
Make sure that all connections fit tightly together. Ensure that the Ethernet and Console cables are correct for use with the AVS 3120. (See Chapter 1, “Product Overview.”)
6.Power up the AVS 3120. Is the problem resolved?
–Yes. The connections were loose. You have fixed the problem.
–No. Call your service representative. Refer to the “Obtaining Technical Assistance” section on page xvii.
