Chapter 6 Voice Feature Card
Replacing PVDM2 Modules in the Voice Feature Card
Caution
Handle PVDM2 modules by the card edges only. PVDM2 modules are ESD-sensitive components and
can be damaged by mishandling.
Step 3
Remove one PVDM2 module at a time. To lift the PVDM2 module out of its socket, pull the locking
spring clips on both sides outward and tilt the PVDM2 up, free of the clips.
Step 4
Hold the PVDM2 module by the edges with your thumb and index finger and lift it out of the socket.
Place the removed PVDM2 module in an antistatic bag to protect it from ESD damage.
Step 5
Repeat
Step 2
through
Step 4
for each PVDM2 module you are removing.
Installing PVDM2 Modules in the Voice Feature Card
To install PVDM2 modules in the voice feature card, perform the following steps:
Step 1
Attach an ESD-preventive wrist strap.
Step 2
Find the appropriate PVDM2 slot on the voice feature card. (See
Figure 6-13
.)
Caution
Handle PVDM2 modules by the card edges only. PVDM2 modules are ESD-sensitive components and
can be damaged by mishandling.
Step 3
Hold the PVDM2 module with the polarization notch pointing toward the back of the voice feature card,
with the connector edge pointing down. (See
Figure 6-14
.)
Caution
It is normal to feel some resistance, but do not use excessive force to install the PVDM2 module into the
socket, and do not touch the surface components. If the PVDM2 module does not fit easily into the
socket, remove it and check the orientation of the alignment holes and polarization notch.
Step 4
Insert the PVDM2 module into the connector slot at approximately a 45 degree angle to the voice feature
card. (See
Figure 6-15
.) Gently press the PVDM2 module down, using as little force as possible. When
the PVDM2 module is properly seated, the socket guide posts fit through the alignment holes, and the
connector springs click into place.
Step 5
Ensure that each PVDM2 module is straight and that the alignment holes (as shown in
Figure 6-15
) line
up with the plastic guides on the socket.
