RLX-EQUIPPED CIRCUIT CROSS-CONNECTS
Summary: RLX modules can be configured to supply span power over the DS1 pairs to power
the repeater modules. To remove current from the pairs before making cross-connects, partially
withdraw each RLX module from the chassis so that electrical contact with the rear connector is
broken. Make necessary cross-connects, then re-install the RLX modules.
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 chassis cover.
2. Use the ejector at the bottom of each RLX front panel to carefully disengage the module
from its connector.
3. Partially withdraw each RLX module from its mounting slot to break electrical contact with
the backplane connector.
Note: The RLX can be configured to supply span power over the DS1 pairs to supply
power to the repeater modules. Partially withdrawing the RLX ensures that current is not
present when cross-connects are installed.
4. At the central office, make necessary cross-connects at the Main Distribution Frame or
other facility, in accordance with local practice.
5. At the remote location, make necessary cross-connects at the remote distribution frame or
other facility, in accordance with local practice.
6. Insert the RLX modules into their mounting slots.
