CRS-170A Switch DIP Settings

The 'Switch Conditions' DIP switches are set depending upon the type of Tx or Rx
traffic conditions resultant of switchover. Some modems have additional settings or
alarm masks that affect conditions – refer to the individual modem manual for
detailed explanations.
Figure 3‐4 shows the DIP switches for setting the 'Mode' and 'Switch Conditions' on the
Antenna Side of the CRS‐170A L‐Band 1:1 Redundancy Switch (towards the BUC and LNB). The
difference of the 'Mode' DIP switch silk screening between the original and current (i.e., Rev. A
and later) versions of the CRS‐170A is illustrated here.
On the next page, Table 3‐1 illustrates the settings for the 'Mode' DIP switch set on a per‐
modem basis, and the 'Switch Conditions' DIP switch settings that determine switchover
functionality for a given redundancy configuration.
