6.4.4.3.3 Config | Redundancy
Comtech EF Data SSPAs are designed to automatically sense and configure into
Redundancy Mode when the redundant loop cable is connected between the two
(i.e., 1:1) or three (i.e., 1:2) SSPAs comprising the redundant subsystem. The
designation of each CPA in a redundant subsystem is determined automatically
via the redundancy interface cable connected – polling on the dedicated
redundancy bus will not begin until the redundancy loop cable is connected.
Use this page to control the operational parameters for redundant operations. The page
identifies the active Redundancy Mode as “OFF”, “ON, SSPA Backup Unit, 1:1” or “ON, SSPA
Backup Unit, 1:2”, and the appearance of the page itself varies depending on its Operating
Mode.
