Section 1.3: Mounting the Serial Interface Board (SIB-NET)
The SIB-NET mounts on the ICA-4L chassis. The AM2020/AFP1010 system connects to and interfaces to the
network through the MIB and the SIB-NET. The MIB mounts onto the SIB-NET. The chassis is compatible
with the ICA-4. For more information on the ICA-4L, refer to the installation section in the AM2020/AFP1010
Manual.
The following example illustrates installation of a SIB-NET in the front left-hand position of an Interconnect
Chassis Assembly. Installation of boards in remaining ICA-4L positions involves a similar procedure.

Step 1
Place the SIB in front of the Interconnect Chassis As-
sembly (ICA-4L) in the installation position. Tilt the
SIB into the ICA-4L and align the square slots on the
board with the first set of four tabs on the ICA-4L as
illustrated.
Step 2
Carefully push the SIB-NET back to the first level.
Slide the SIB-NET away from the ICA-4L until it is
directly over the second set of four tabs, now located
immediately behind the printed circuit board.
Step 3
Push the SIB-NET back so that it rests on the four
tabs behind the board. Slide the board in toward the
center of the ICA-4L and carefully engage the socket
connector on the SIB-NET with the plug connector
on the ICA-4L. When correctly seated, a mechani-
cal tab will stop the SIB-NET. Seating the connec-
tor and plug requires applying some force. Before
applying force, carefully check alignment of all pins.
When installed, the SIB-NET seats in a channel con-
sisting of four retaining tabs in front of the printed
circuit board and four retaining tabs in back of the
printed circuit board.
