Using Avaya M440 Gate Switch 6U Modules

Permissible 6U Modules and their Location

The Avaya M770 supports all switching modules (LSA+, LSE-108, LSE-208, LSE-404, LSE-404S, LSE-808, LSF-100, LFE-100, LFE-1008, LFE-4004, LFE-4004S, LBT-155, LHB, LEB-200 and 3LS) but not shared Ethernet modules. All Avaya M440 modules can be inserted into the hub, using a module adapter (see following section). There are several considerations to keep in mind when using Avaya M440 modules:

1The NMA-RS agent module should be inserted into slot 13 and 14 of the hub.

2The NMA-RE agent module should be inserted into slot 14 of the hub.

3You can use the LSE-MON module only if you set its internal jumper to Clock Disable (applicable only to C/S version D and up).

Using the 6U Module Adapter

This section explains how to insert 6U Avaya M440 modules in the Avaya M770 hub using the optional adapters.

Two types of adapters are available:

1M-LS1 single-slot 6U module

2M-LS2 dual-slot 6U module.

Use the type appropriate for the 6U module you are inserting.

Caution: The 6U modules contain components which are sensitive to electrostatic discharge (ESD). To prevent ESD damage handle the module by its edges and do not touch the circuit board components unless instructed to do so.

Before handling the module, touch the Avaya M770 chassis to discharge any electrostatic charge on your body.

In order to use the adapter perform the following steps:

1Insert the adapter into the Avaya M770 until the adapter is correctly sited, and tighten the adapter screws.

2Insert the 6U module gently into the adapter as shown in Figure 5.1.

3Gently tighten the module’s retaining screws.

To remove an adapter:

1Release the module’s retaining screws, and pull the module out by its handle.

2Release the adapter’s screws, and pull the adapter out.
