Use this procedure to install the power feeds from a -48 V DC or 110 V

AC power source to the BitStorm 1900 modem shelf.

NOTE: The filter shelf does not require a power feed.

Requirements

This procedure requires the following:

•Volt-ohm meter

•BitStorm 1900 DC power harness

•-48 V DC power fuse bay or AC-to-DC rectifier or 110 V AC power

Power supply and wiring specifications are described in "Appendix A.

Installation Requirements," on page 107.

Step Procedure

1.)

2.)

Eject all cards (Power, MIU Shelf Processor and Modems) from the backplane of the shelf. Ensure that the cards completely dislodge from their backplane connectors.

WARNING: POSSIBLE EQUIPMENT DAMAGE! Never connect untested power to the BitStorm 1900 with any circuit packs installed. The BitStorm 1900 shelf and rectifier could be seriously damaged if the power feed polarities on a -48 V DC power supply are reversed.

Route and connect a ground wire from the building’s grounding facility to the ground stud on the side flange of the shelf. Refer to the Appendix A section "Grounding Environment Specifications," on page 109 for the BitStorm 1900 grounding requirements.
