NSTALLATION
a
Carefully insert the CIM into the socket, with the CIM angled toward the front
of the card and the CIM components facing the front of the card (arrow 1).

Inserting the DSP CIM into the Socket
b
Carefully move the CIM into the vertical position (arrow 2). The socket clips
automatically engage the CIM as you move it into position.
CAUTION:
The DSP CIMs are keyed so that you can insert them only one way.
Do
not force the CIM into position
. If you are having trouble engaging the CIM in the
socket, then you probably inserted it facing the wrong way in step 6a. Make sure
that the large components on the CIM are facing the front of the card.
c
Repeat steps a and b, as necessary, to install additional CIMs.
The T1 voice compression module supports up to three DSP CIMs, while the E1
voice compression module supports up to four DSP CIMs.
8
Replace the RAM module in the front socket, using the same procedure that you
did to install the DSP CIMs.
The RAM module is common to all the DSP CIMs. In order for the DSP CIMs to
operate, you must re-install the RAM module.
a
Insert the RAM module into the front socket, angled toward the front of the
card and with the large components facing the front of the card.
b
Carefully move the RAM module into the vertical position to engage the socket
clips.
