PERATION
Step
Procedure
1
Set both units to "Auto" redundant mode by sending them RAM=1.
2
Establish the current online status by sending each unit an ONL? query. Note one unit
should return ONL=1 (online) and one unit should return ONL=0 (offline)
3
Fail the unit that reported ONL=1. The switch should throw. Restore the unit
4
Repeat the ONL? to both units. The unit that was failed in step 2 should now report ONL=0
and the other should report ONL=1. Fail this unit and confirm the switch transitions.
5
Put the system in "Manual" mode by sending RAM=0 commands to both units.
6
The "SSW" command will force the switch to point to the selected unit. For example, an
"SSW=1" command will force the switch to point to SSPA 1 no matter which SSPA the
command was issued to. Ensure either unit can throw the switch in both directions by
sending the following commands
a. <1/SSW=1 (the switch may or may not transition)
b. <1/SSW=2 (the switch should transition)
c. <1/SSW=1 (the switch should transition)
d. <2/SSW=2 (the switch should transition)
e. <2/SSW=1 (the switch should transition)
