3 – Installation & Wiring
3.2.3.4 Channel Module Insertion
To install a TDM channel module, orient the eject tab toward the bottom of the shelf (in a 3RU shelf)
or toward the right of the shelf (in a 1RU shelf) and slide the module into the desired slot on the front
of the shelf until it meets the connector on the front of the midplane. From the rear of the shelf, slide
the module adapter into the corresponding connector on the back of the midplane.
Warning! Do not attempt to install TDM channel modules upside down. When the module is inserted,
the eject tab should be at the bottom on a 3RU shelf or at the right in a 1RU shelf.
Verify that all modules are seated securely in position.
Warning! Hot insertion or removal of a module adapter while a channel module is in place is not
recommended, as it could damage the channel module or the module adapter. To
remove a module adapter while the system is turned on (has power), first remove the
associated channel module. Similarly, to install a new channel module, first install the
module adapter and then install the module itself.

Power Supply Installation

3.2.4.1 Main Power Supply Installation
NetXpress LX multiplexers normally ship pre-configured, with modules, module adapters, and power
supplies already installed. Power supply modules require no special setup. As long as they are plugged
into their slots and system power is applied, they are operating.
3.2.4.2 Redundant Power Supply Installation
Each 3RU NetXpress LX shelf can contain a second power supply for redundancy. If the main supply
fails, the system continues operating using the redundant supply. Simply insert the second power
supply into the redundant supply slot on the front (its indicators will light up identically to those on the
main supply). Due to space limitations, 1RU shelves do not have the capacity for redundant power
supplies.
If a 3RU shelf is equipped with two power supplies (main and redundant) and one of the supplies fails,
it may be removed and a new supply inserted without powering down the system.
3.3 Wiring & External Connections
Your NetXpress LX multiplexer must be completely wired before placing any payload circuit into
service. Installation and wiring should ONLY be performed by trained professionals.
Warning! The CM-30 module contains a replaceable battery. There is a danger of explosion if the
battery is incorrectly replaced.
Only replace this battery with the same or equivalent type recommended by the
manufacturer. Dispose of used batteries according to the manufacturer's instructions.
Figures 3-7 and 3-8 identify the rear panel connectors for the 3RU and 1RU equipment shelves,
respectively.
