Installing a D3LX RMT Module in a Remote Cabinet

LTPS-UM-8013-03

 

 

TWO-POSITION QLX REMOTE BNC CHASSIS INSTALLATION

 

To install first the working module, and then the protect module (if installing D3LX RMT modules in protection switching applications):

1Open the front panel of the remote terminal into which the D3LX RMT will be installed.

2Route the fiber patch cord through the left side of the fiber management enclosure located on the remote terminal as shown in Figure 10. The protective cover must remain on the fiber connector to prevent dust and damage to the connection. The fiber should be tagged to identify the circuit.

Figure 10. D3LX RMT Module Locations in a Two-Position QLX Remote BNC Chassis

3Locate the mounting slots designated for the D3LX RMT modules in the chassis.

4Refer to Figure 10 for D3LX RMT module locations chassis and slot corresponding to the DS3 signal.

5Remove a new module from its protective ESD packaging. If the module is installed, remove it and inspect for physical damage.

6Align the module with the slot and slide the module into the chassis until about three inches protrude from the front of the chassis. Do not seat module in connector at this time.

7Remove the protective dust cap from the connector on the D3LX RMT module.

8After removing the protective cover from a fiber patch cord, confirm that the fiber-optic connector is free of debris as directed in “Appendix B - Cleaning and Mating Fiber-Optic Systems” on page 39.

9Proceed to “Power Verification” on page 16.

POWER VERIFICATION

Verification of Electrical DS3 Power Level

1Apply power to the D3LX RMT.

2Attach the fiber patch cord from the D3LX RMT to a meter.

3Confirm that the readings are within the specification (-5 dBm to -23 dBm).

If the reading is not within the specification, check all fiber-optic connections to the D3LX RMT. If the reading is still not within the specification, replace the module.

4Once the readings are within specification, disconnect the patch cord from the meter.

Now that the DS3 power level meets optical specifications, verify the D3LX RMT module.
