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 524-2 for 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.
