Transition Networks CSDTF1022-100 instruction manual Fault Isolation and Correction, Yes

FAULT ISOLATION and CORRECTION

If the media converter fails, isolate and correct the failure by determining the answers to the following questions and then taking the indicated action:

1.Is the P(o)W(e)R LED on the media converter illuminated?

NO

•Is the media converter inserted properly into the chassis?

•Is the power cord properly installed in the chassis and at the external power source?

•Does the external power source provide power?

•Contact Technical Support: (800) 260-1312.

YES

•Proceed to step 2.

2.Is the SDF (Signal Detect/Fiber) LED illuminated?

NO

•Check fiber cables for proper connection.

•Verify that TX and RX cables on media converter are connected to RX and TX ports, respectively, on other media converter.

•Contact Technical Support: (800) 260-1312.

YES

•Proceed to step 3.

3.Is the SDC (Signal Detect/Copper) LED illuminated?

NO

•Check twisted pair cables for proper connection.

•Check RJ-45 Pinning Switch for correct twisted pair cable configuration.

•Check integrity of device attached to media converter by twisted- pair cable.

•Contact Technical Support: (800) 260-1312/(800) LAN-WANS.

YES

•Contact Technical Support: (800) 260-1312/(800) LAN-WANS.
