3-10 Bench Setup and Operation
SG4000 Installation and Operation Manual
The EPIM board contains jumpers J4 through J9 (illustrated in Figure 3-10) that determine the
primary and secondary receiver. The EPIM then activates receiver one or two based on the
jumper position. Refer to Section 4, “Modules,” Embedded Plug-in Module for more information
regarding its use.
Figure 3-10 illustrates the suitcase jumpers located on the EPIM.

To set up the forward redundant-split, two-receiver option:
1 Install SG4-R/* receivers in lid optics slots 1 and 2, as illustrated in Figure 3-7.
2 Install a forward redundant-split board in the forward configuration board location 1, as
illustrated in Figure 3-7.
3 Connect an RF cable from each SG4-R receiver to the input of the forward redundant-split
board. The board has SMB connectors that are labeled primary (
PRI) and secondary (SEC).
4 Connect the appropriate forward RF cables from the SG4-RF modules to the forward
redundant-split board.
5 Position jumpers J7 and J8 on the forward redundant split board (Figure 3-8) as required for
the number of active outputs you are using.
6 Ensure that the PIC cable is properly connected to the lid router board and center power
distribution board in the housing base.
7 Ensure that the SIC cable is properly connected to the EPIM and center power distribution
board in the housing base, as illustrated in Figure 3-7.
8 Move the jumper on the EPIM board from the SW1 AUTO to the SW1 A position, thereby
disabling receiver two. See Section 4, “Modules,” Embedded Plug-in Module for detailed
information on the switch and jumper settings.
9 Route the fiber service cable into the node and fiber tray.
10 Measure the optical input power on the primary and secondary forward pigtails, leaving
enough length to connect them to the receiver bulkhead connectors.
11 Apply power to the node (see Powering the Node in this section). Allow five to ten seconds
for the system self diagnosis to complete.
12 Connect the service cable to the primary and secondary receiver bulkhead connectors.
