Each RF Multiplexer module is capable of controlling up to two Expander
modules, providing a total of eighteen (4:1) banks. The Expander modules
can be physically located in the C-Size mainframe next to the RF
Multiplexer, or up to eight meters away using extension cables. Use Figure
2-3 and the following procedure to connect the Expander modules.
1 Verify a 3-1 cable (part number E1472-61601) is installed in the
Remote Module Driver (RMD) 2/4/5 cable slot. Cable can be
connected without removing the shield.
2 Cut the cable ties holding the cables, and pull the cables through the
slots in the shield.
3 Mark the 3-1 cables as shown in Figure 2-3 (cross out unused RMD
number).
4 Connect the 3-1 cables to the Expander modules as follows:
- RMD3 cable to Expander (module 01) Bank 3-5 connector.
- RMD2 cable to Expander (module 01) Bank 0-2 connector.
- RMD5 cable to Expander (module 02) Bank 3-5 connector.
- RMD4 cable to Expander (module 02) Bank 0-2 connector.
NOTE
RMD1 cable is connected to E1472A/74A (module 00) Bank 3-5 connector,
and RMD0 cable is connected to E1472/74A (module 00) Bank 0-2
connector at the factory. These connections are not accessible with the
shield in place and should not be moved.
5 If the Expander module is physically located (up to eight meters)
away from the mainframe, you can daisy chain up to 10 extender
cables (part number E1473-80002) for each RMD connection (see
Figure 2-3, module 02).
6 Fold and tie unused RMD cables.
