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 power adapter the proper voltage and cycle frequency for the AC outlet? NOTE: Refer to the “ Power Supply Requirements” on page 7. • Is the power adapter properly installed in the media converter and in the outlet? • Contact Technical Support: (800) 260-1312/(800) LAN-WANS. 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/(800) LAN-WANS. 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 pair cable. • Contact Technical Support: (800) 260-1312/(800) YES • Contact Technical Support: (800) 260-1312/(1 2 3 4 toward network connectors SHORT HAUL Switch Settings* RIGHT SWITCH SET 1 2 3 4 1 2 3 4 toward chassis LONG HAUL Switch Settings* 1 2 3 4 DSX-1 533'-655' 100 ohm cable DSX-1 399’ -533’ 100 ohm cable DSX-1 266’ -399’ 100 ohm cable DSX-1 133'-266' 100 ohm cable DSX-1 1 0’ -133’ and ANSI T1.403 100 ohm cable DSX-1 6.0V 100 ohm cable -22.5db 100 ohm cable -15db 100 ohm cable -7.5db 100 ohm cable 0db 100 ohm cable *Right *Right INSTALLATION (continued) Install Cable COPPER T1 100 OHM (RJ-45 CONNECTOR) 1.
