IFC Networking—Serial Interface Board (SIB-NET) 7
Mounting and Connections
The IFC-1010/2020 system can use one to three Interconnect Chassis
Assemblies (ICA-4/ICA-4L), depending on the specific installation
requirements (the IFC-1010 can use only one). The ICA-4L is a
low-profile mounting chassis that replaces the ICA-4 in all BE-1010 and
BE-2020 basic equipment kits. The ICA-4L is fully compatible with both
CAB-2 and CAB-3 Series cabinets and the ICA-4 chassis.
In order to accommodate the SIB-NET, the chassis used in Tier 1 (top row
of the IFC panel) of the CAB Series cabinet must be an ICA-4L chassis. In
the remaining tiers of the CAB cabinet, either the ICA-4 or ICA-4L can be
used. The following procedure details how to mount the ICA-4L chassis.
Follow the procedures below if using more than one ICA-4L:
1. Interconnect each ICA-4L before installation to the backbox by
mating the plug connector on one chassis to the socket connector on
the other (no cable required).
2. Align the entire ICA-4L assemblies over the studs in the backbox.
3. Connect a chassis grounding cable (71073) for each board installed on
the ICA-4L to the ICA-4L enclosure. (Two cables are required when a
SIB-NET is connecting to a MIB-W or MIB-WF.)
4. Secure the assemblies and cables with the provided nuts and washers.
Each ICA-4L is marked TOP for proper orientation.
Note: The ICA-4L with the SIB-NET interface card must be in the
top tier in the CAB-2 or CAB-3 Series enclosure. For the
correct placement in the ICA-4L chassis of all of the circuit
boards, see Installing the IFC-1010/2020 Technical Bulletin
(LIT-448155).
IMPORTANT: When connecting an ICA-4 to an ICA-4L, there is an
extra pin on the ICA-4L, which must go in front of the
connector.
