Installing DSL Cards

HANDLING PRECAUTIONS FOR STATIC-SENSITIVE DEVICES

This product is designed to protect sensitive components from damage due to electrostatic discharge (ESD) during normal operation. When performing installation procedures, however, take proper static control precautions to prevent damage to equipment. If you are not sure of the proper static control precautions, contact your nearest sales or service representative.

A Hotwire 87xx Termination Unit can be installed, removed, and replaced from a DSLAM chassis without disrupting service to the other cards in the chassis.

" Procedure

To install the Hotwire 87xx Termination Unit:

1. Determine in which slot the unit will be installed. Verify that cards in adjacent slots have been fastened.

2. Remove the filler plate from the installation slot and store for possible later use.

3. Insert the unit:

— For a Hotwire 8610 DSLAM chassis – hold the Hotwire Termination Unit

horizontally with component side facing up and insert it into the left and right card guides.

4. Slide the unit into the slot until the power and network connectors seat firmly in the mating connectors on the backplane.

CAUTION:

Do not force the unit into the slot. This could damage the backplane connectors. If the card does not seat properly, remove the card and reinstall it. If it still does not seat properly, call your service representative.

The unit performs a power-on self-test. All of the LEDs turn ON and OFF briefly. When the self-test is completed successfully, the SYSTEM OK LED begins to pulse.

5. If the LED is not pulsing, refer to Monitoring and Troubleshooting in the User’s Guide.

6. Secure the unit by fastening the screws at each end of the faceplate.

Connecting to the DTE

Connection to the eight DTE ports of the Hotwire 87xx Termination Unit is through the 50-pin interface connector on its faceplate. Refer to Connector Pin Assignments in the User’s Guide.

" Procedure

To connect the Hotwire 87xx Termination Unit to your DTEs:

1. Insert and fasten the hex-head jackscrew included with the unit into the top nut (the nut nearest the LEDs) on the 50-position connector on the faceplate.

2. Connect the 50-position connector of the cable to the connector on the faceplate. Align one end of the cable connector with the card connector, then push on the cable connector until it seats.

3. Fasten the captive screw in the top of the cable connector to the hex-head jackscrew.

4. Secure the bottom of the cable connector to the unit using a cable tie.

5. Feed the cable through the Cable Guide if it is installed. When all cables are

installed, anchor them with cable ties to the rack, DSLAM, or Cable Guide.

6. Connect the terminating connectors to your DTEs.

Connecting to an MDF

You can connect the Hotwire DSLAM chassis containing the Hotwire 87xx Termination Unit to an MDF or other demarcation point. Do not connect it to a POTS splitter.

" Procedure

To connect the Hotwire DSLAM chassis containing the unit to an MDF:

1. Plug the Telco 50-pin cable into the appropriate line port on the chassis:

— For a Hotwire 8610 DSLAM chassis – Line connectors are numbered 1–3 on

the back of the chassis. After installing the connector, insert a cable tie through the tie mount to hold the cable in place.

— For a Hotwire 8810 DSLAM or 8820 GranDSLAM chassis – Line connectors

are numbered 1–18 on the back of the chassis.

2. Make sure the other end of the cable is connected to the appropriate MDF or demarcation point.

Refer to Connector Pin Assignments in the User’s Guide for pinouts.

NOTE:

If you are connecting the Telco 25-pair, 50-pin cable to an MDF, a converter may be necessary for terminating the other end of the cable on a punchdown block before cross-connecting to an MDF.
