5.3.1.4 CONFIG: Redundancy Menu Branches
Comtech EF Data’s CPA family of 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) CPAs 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.
This display indicates the current operating mode – Standalone or Redundancy. When the CPA
is operating in Standalone mode – that is, no additional CPAs are recognized as active – the
display appears as follows:
Redundancy Mode: OFF
(E)
Press ENTER or CLEAR to return to the previous menu.
With the CPA in Standalone mode, the nested menus that follow will not be visible/selectable.
Otherwise, when a valid redundancy configuration is detected, a read-only display will first appear:
If 1:1 Redundancy is recognized:
Redundancy Mode: ON
SSPA #BU 1:1 (E)
If 1:2 Redundancy is recognized:
Redundancy Mode: ON
SSPA #BU 1:2 Pri=1 (E)
Press ENTER to continue to configure 1:1 or 1:2 redundant operations, or press CLEAR to return to
the previous menu.
If 1:1 Redundancy is recognized:
Config: Auto/Manual Mode
Backup Mode
