CRS-150 Switch DIP Settings
Two configuration switches are provided on the front panel of the CRS-150 L-Band 1:1
Redundancy Switch (see
Figure 5-2
). These ‘
Switch Mode
’ DIP switches control the conditions
that initiate an automatic switchover.
Figure 5-2. CRS-150 Front Panel – DIP Switches
Table 5-1
illustrates the settings for the ‘
Switch Mode’
DIP switch settings that determine
switchover functionality for a given redundancy configuration.

RECOMMENDATION:
Comtech EF Data recommends that for most applications, the CRS-150 should be
configured for Switchover upon a Unit fault only.
Once switchover functionality has been assigned, the modems in redundancy handle faults and
alarms based on the combination of the ‘Switch Mode’ DIP settings, and how faults and alarms are
handled by the modems,as configured using the
(Select:) INFORMATION: ALARM-MASK
menu via the CDM-600 front panel:
ALARMS MASKED: TX-AIS RX-AIS BUF-SLIP
AGC EBNO SAT TERR
This modem screen shows only any alarm(s) designated as currently
masked
;
if an alarm is
not
masked, the relevant screen position of that feature is replaced with a blank space. For detailed
information on possible fault conditions and alarm masking in general, see
Chapter 5. FRONT
