Figure 3-6. CM-30 Module and MA-230 Midplane Insertion
To connect the CM-30 module and MA-230 module adapter, perform these steps:
1. Slide the MA-230 module adapter from the rear of the shelf toward the connector on the midplane.
Secure the MA-230 adapter to the back panel with the two Phillips screws that are provided.
2. Slide the CM-30 module into the designated slot from the front of the shelf toward the connector
on the midplane. Do not exert too much pressure. Both the module and the module adapter
should fit snugly onto the pins of the corresponding midplane connectors.

Channel Module Installation

A 1RU NetXpress LX shelf can accommodate up to five channel modules, while a 3RU NetXpress LX
shelf can accommodate up to 17 channel modules. Most existing Intraplex TDM channel modules are
compatible with the NetXpress IP multiplexer (Section 2.5.1 - Compatibility with Intraplex TDM
Channel Modules).
TDM channel modules can be installed in slots 2 through 6 on a NetXpress LX 1RU shelf and slots 2
through 18 on a NetXpress LX 3RU shelf.
Note: When installing any channel module, you must install the corresponding module adapter first.
3.2.3.1 Module Adapter Installation
Each Intraplex TDM channel module requires an installed module adapter (MA) to provide an electrical
interface to external equipment. Before plugging a channel module into the shelf slot, install the
module's associated module adapter into the matching slot on the back of the chassis.
3.2.3.2 Remote Control Operation
Each TDM channel module includes a small switch labeled REMOTE. To allow remote management of
the TDM channel modules via the NetXpress LX Home page or SNMP, enable the REMOTE mode on
each module.
3.2.3.3 SCB Address Selection
In order to permit remote management of the TDM channel modules via the NetXpress LX Home
page or SNMP, you must assign a unique SCB address for each module installed into the NetXpress
chassis. For consistency and ease of identification, you should set the SCB address to match the
physical slot occupied by the channel module within the NetXpress chassis. Channel modules installed
have access to bus TDM1A or bus TDM1B.
Note: Remove a module from the shelf before changing the SCB address.
