7 Install the DSP CIM(s), as shown in Figure 16, keeping in mind that you must
install the CIMs contiguously from back to front, always ending with a CIM in the
socket adjacent to the front socket, which is reserved for the RAM module.
If you are installing one CIM, install it in the socket adjacent to the front (RAM
module) socket.
If you are installing two CIMs, install the first CIM in the third socket back and
the second CIM in the socket adjacent to the front (RAM module) socket.
If you are installing three CIMs, install the first CIM in the fourth socket back,
the second CIM in the third socket back, and the third CIM in the socket
adjacent to the front (RAM module) socket.
If you are installing four CIMs (supported for E1 voice compression modules
only), install the first CIM in the rear socket, the second CIM in the fourth
socket back, the third CIM in the third socket back, and the fourth CIM in the
socket adjacent to the front (RAM module) socket.
