Configuring the Unit Usin g the Internal Switches

Use internal Switchpacks S3 and S4 to manually configure the unit. Use Figure 1,

Hotwire 797x Standa lone Termination Unit Switchpack Loc ations, to lo ca te Sw itc h pac ks

S3 and S4.

HANDLING PRECAUTIONS FOR STATIC-SENSITIVE DEVICES

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

Procedure

To configure the uni t usi ng internal Switchpac ks S3 and S4:

1. Power off the unit. Remove the enclosure cover by removi ng the two screws at the top of the unit, then pushing a flat-bl ade sc rewdri ver through the slots on both sides of the housing to free the four in ner latches.

2. Locate Swi tchpac k S4 on the c ircui t boar d us ing Fi gure 1, Hot wire 797x S tandalo ne

Termination Unit Switchp ack Locations.

3. Set Switch 1 on Switchp ack S4 to ON to enable Switchpacks S3 and S4.

4. After you enable the switchpacks, you must set the swit ches to your desired

configuration. Refer to Figure 1, Hotwire 797x Standalone Termination Unit

Switchpack Locations, and Table 12 through Table 22.

5. Replace and secur e the cover.

6. Power on the board to reset and enable the new configuration.
