Installing the DAP
Overview
The following steps must be completed to install the Excalibur Multirate DAP:
1. Place the unit in a suitable location.
2. Connect the unit to the DTE, telephone lines, and accessory equipment.
3. Set the jumpers on the printed circuit (p.c.) card.
4. Connect the power supply to the DAP and the AC power outlet.
This chapter explains how to perform each of these procedures. It also contains
pin/signal assignments for each of the DAP's connectors and descriptions of the cables
used with each connector.
Note: This chapter explains how to install the standalone version of the Excalibur
Multirate DAP. For instructions on installing the central site version, refer to the
Excalibur Card Carrier Installation and Operation Manual.
Unit Placement
The first step in installing the Excalibur Multirate DAP is to place it in a suitable
location. The DAP can be placed on any stable, flat surface or it can be mounted in a
standard 19-inch (48 cm) equipment rack using the optional Rack Mount Kit (Part No.
900-1213A-2). An optional Wall Mount Kit (Part No. 900-1219A-2) is also available
with the unit. Installation instructions are provided with both of these kits.
Whether placed on a flat surface or in a rack, the installed DAP must meet the following
requirements:
• The physical location must permit cable connections at the rear panel.
• The front panel must be accessible and visible.
• The air intake and exhaust must not be obstructed.
• The DAP must be physically stable and protected from corrosive spray or
atmosphere.
