Installing the SSM3 Module
The following procedure describes how to install the SSM3 module onto the Acme
Packet NIU card.
Prerequisites:
•
Wear an ESD wrist strap or take similar equivalent actions to prevent static
damage to the NIU card or other ESD-sensitive components.
•
Place the new SSM3 module in an ESD-safe location.
•
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)
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).
2.
Press evenly across the top of the connector to fully seat the SSM3
module on the NIU PCB as shown below. Note that the SSM3 is fastened
to the connector at one end while at the other end, the board rests
on two standoffs attached to the NIU as shown in the figures below.
3.
Using the Phillips screwdriver, insert and tighten the four standoff screws to secure
the SSM3 module to the PCB.
