Installing the Module

The ATM access modules contain components sensitive to electrostatic 

discharge. Do not touch the circuit board unless instructed to do so.

The Avaya M770 chassis must not be operated with the module slot open; the 

slot should be covered with the supplied blanking plate if necessary.

M-ACC modules are hot swapable.

The M-ACC occupies one slot in the Avaya M770 chassis and can be inserted into 
any available slot.
The M-ACC can be installed or removed while power is on.
To install the M-ACC:
1

Hold the module (shaped like an upside down L) using both hands. The colored 
module name panel and LEDs should be on top (see Figure 3).

2

Fold out the plastic handles on the top and bottom of the front panel.

3

While holding the module by its handles, place it onto the top and bottom guide 
rails in the hub and gently slide it in.

4

Plug in the module by pressing firmly on the mid-section of the front panel. 
Fold down the handles and secure the module using the two screws at the top 
and bottom of the front panel. Do not over-tighten the screws.

5

Connect the Switch to the ATM network as described in Connecting a Cable to 
the ATM Port40.

6

Follow the post-installation checks, as described in Post-Installation Checks42.

Even though the modules are hot-swappable a short self initialization period 

is required when inserting or removing them from the hub. Allow at least 5 seconds 
initialization time between modules when inserting or removing several modules.
