Installing the SSM3 Module

The following procedure describes how to install the SSM3 module onto the Acme Packet NIU card.

Prerequisites:

• Place the new SSM3 module in an ESD-safe location.
• Wear an ESD wrist strap or take similar equivalent actions to prevent static damage to the NIU card or other ESD-sensitive components.
• Note the location of the SSM3 module connector on the NIU card.
• #2 Phillips screwdriver
• Standoff screws (stored after removing the SSM3 module or available with the new SSM3 module)

  To install the SSM3 module:

1. Grasp the SSM3 module along either side of the connector between your thumb and index finger and join the module connector to the NIU connector by pressing evenly across the connector until the module is fully seated (see below).
