3.2 Installation
3.2.1
Shelf Installation
All channel modules, common modules, module adapters, and power supplies plug into the main
equipment shelf (Figure 3-1). As a standard practice, a NetXpress LX shelf ships pre-configured with
the CM-30R module, channel modules, module adapters, and power supplies installed. All modules
and module adapters can remain in place while you install each shelf into its designated equipment
rack.
Figure 3-1. NetXpress LX 1RU and 3RU Multiplexers
Consider these points for equipment shelf installation:
●
If applicable, bolt the shelf into the designated equipment rack. If multiplexers are to be stacked
in an equipment rack, allow at least 1RU space between shelves when using DC supplies, or 2RU
space between shelves when using AC supplies, to avoid any potential heat concerns.
●
Make sure all modules, module adapters, and module interface units are properly seated.
Note:
If the shelf is AC powered, make sure the power cable can be accessed easily for maintenance
purposes.
3.2.2
CM-30R Module Kit Installation
If you purchased a CM-30R module kit, which includes the CM-30R interface module and an MA-230
module adapter, use these steps and guidelines to install the module and module adapter in your
Intraplex multiplexer.
3.2.2.1 CM-30R Module and Indicator Lights
The CM-30R IP interface module is pre-installed into the NetXpress LX multiplexer at the factory.
However, you may need to access and service the module at some point. Insert the CM-30R module
(Figure 3-2) into the same slot number as the MA-230 module adapter in the NetXpress LX-100 (1RU)
chassis or NetXpress LX-300 (3RU) chassis. The LXR-100 and LXR-300 will each contain two CM-30R
modules, installed into the slot numbers shared with the MA-231-1 and MA-231-2.
