6.0TROUBLESHOOTING GUIDE

6.1OVERVIEW

The GX/TM2 module has several LED indicators available to assist in the determination of problems. Refer to Section 3.5, Verify Operation, for LED definitions.

6.1.1Power Issues

Problem:

The Power LED does not illuminate after installation is complete or no LED indicators are ON

Possible Causes:

A. For standalone modules, confirm that the power supply is connected to both the module and the AC or DC power source. If Power LED is still not illuminated, use a voltmeter and check the voltage of the power source (AC/DC converter used with the standalone unit should measure between 9 -15 VDC no load at the barrel connector).

B. For plug-in module, confirm that the chassis is connected to an AC or DC power source. If the Power LED is still not illuminated, remove the module and verify the operation of other modules in the chassis. If power is present and the module will not turn ON, replace the module.

C. The plug-in module requires ~ 3.6 watts (3.3VDC @ 1.1 amps) for normal operation. The AC Power Supply in a 19-Module Chassis can supply ~ 60 watts (3.3VDC @ 18amp). A fully loaded 19-Module chassis of GX/TM2 modules will require two power supplies for standard operation. This condition will cause the power LED not to illuminate.

6.1.2Fiber Issues

Problem:

The Fiber Optic link LED does not illuminate after installation is complete.

Possible Causes:

A. Verify the Link Mode selection is set to Link Segment (LS). Until a stable link is established, leave the Link Mode configured for LS. After a Link presence is established, the Link Mode selection can be modified.

B. Confirm that the fiber optic cable is properly connected to the iConverter GX/TM2 and the remote fiber optic device. Connecting the fiber between the Tx of the far end to the Rx on the near end will cause the FO LED on the near end to illuminate (only when the link mode is configured for Link Segment). Completing the connection will cause the far end FO LED to illuminate.

C. Confirm that the fiber cable type matches the fiber transceiver type (multimode, single-mode) on the iConverter GX/TM2.

D. If using a dual-fiber model, confirm that the transmitter (Tx) is attached to the receiver side of its link partner, and that the receiver (Rx) is attached to the transmitter. A optical power meter will assist in determining which cable should be connected to the Tx and Rx of the module. To insure proper operation, a minimum of -30dBm must be present at the fiber optic receiver.

E. If using a single-fiber model, confirm that the Tx wavelength on the iConverter GX/TM2 matches the Rx of the connected fiber optic device. Single-fiber units transmit and receive at different wavelengths (1510nm/1310nm). Verify the model numbers to insure proper compatibility.
