ZEPHYR XPORT USER’S GUIDE

Some failures are catastrophic failures, while some are due to the cumulative damage that can occur over the course of several years. For this reason, we recommend that in addition to AC (mains) power protection (see above), that a quality telephone line surge protector be employed at the back panel of the Zephyr Xport. The ground terminal of this device should be connected directly to the Zephyr Xport chassis, and the protector connected to the Xstream’s ISDN and/or POTS Interface jack with as short a cable as possible (under 8 inches). This approach is particularly well suited to situations where you expect nearby strikes, such as when you are located near a tower. See www.telos- systems.com for additional information on telephone line protection.

The Xport can be ordered with, or without, one of the ISDN options. The ISDN interface connectors will not be active if the associated option is not present. You check for the presence of this interface by looking in the About menu option. The two ISDN options are:

•Telos Part # 1701- 00056: for use in the USA & Canada. Allows operation with the ISDN "S" (4- wire) interface or the ISDN "U" (2- wire) interface in the USA and Canada.

•Telos Part # 1701- 00135: For sale worldwide: Supports the ISDN "S" interface.

To Install the ISDN option card, follow the steps below:

1.Disconnect the AC (mains) power cord and all telephone connections from the rear panel of the Xport.

2.Remove the rear bumper of the Xport by gently pulling at the top with your fingers (see photo)

3.Remove the 6 Phillips- head screws around the perimeter of the rear panel.

4.Grasp the rear panel and pull it partially out (see picture below).

5.Look at the bottom of the unit, and locate the green wire going to the power entry module. Disconnect this green wire by unplugging it from the power module. Pull the board out from the chassis.
