RLXIOR INSTALLATION AND TESTING

Summary: This procedure provides instructions for installing the Repeater Loop Extender Intelligent Office Repeater (RLXIOR) module in the chassis. A typical deployment consists of an RLXIOR module installed in a chassis that is connected to a repeater or a series of line repeaters. There is no protection for this signal, and an MPU must be installed to enable configuration and alarm reporting for this module.

The installation procedure consists of unpacking the RLXIOR, setting two configuration switches, installing the RLXIOR in the chassis, and verifying that it is functioning properly. The RLXIOR may be installed in either a Soneplex Broadband chassis or a Soneplex Loop Extender chassis.

Caution: To enable span power on the RLXIOR module, a proper connection must be made between chassis ground and –48V return at a location in the central office, following local practices. It is recommended that this connection be made outside the Soneplex chassis.

Caution: Electronic modules can be damaged by electrostatic discharge (ESD). Before handling modules, wear an anti-static discharge wrist strap to prevent damage to electronic components. Place modules in anti-static packing material when transporting or storing. When working on modules, always place them on an approved anti-static mat that is electrically grounded.

1.Open the shipping carton and carefully unpack the RLXIOR from the protective packing material. See Figure 524-1.

2.Set the configuration switches on the RLXIOR to match the requirement of the work order. See Figure 524-2for the location of switches. The following operating parameters are switch-selectable:

•Line Power (–130 Vdc or ± 130 Vdc)

•Channel Blocking Idle Code (7Fhex or FFhex)

Note: Factory default settings for the RLXIOR switches are –130 Vdc for Line Power and 7Fhex for Channel Blocking Idle Code.

3.Align the edges of the RLXIOR module with the slot guides. Use the ejector to press the module into the backplane connector in one of the module locations, as shown in Figure 524-3.If excessive resistance is encountered, remove the module and check for obstructions or improper alignment.
