4.3 RMI Jumper Configuration Reference (CRS-505)
This section is provided for RMI identification purposes only. All RMIs are shipped
preconfigured and do not require user adjustments.
The CRS‐505 RMI (CEFD P/N PL‐0000293) comes preconfigured for proper operation with the
CRS‐311 1:1 Redundancy Switch using SLM‐5650/5650A modems. Configuration of the ‘JMP1’
jumper setting on the PCB determines whether the module is configured for use with the CRS‐
311 1:1 Redundancy Switch, or for use with the CRS‐500 M:N Redundancy System. Figure 4‐3
shows the ‘JMP1’ jumper location identified on the CRS‐505 PCB.

Table 4‐1 illustrates the ‘JMP1’ jumper settings that are factory‐set for each RMI that is used
with the CRS‐311 1:1 Redundancy Switch and SLM‐5650/5650A modems.
