Modem and Switch Configuration Revision 13

4.9 CRS-170A S witch 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 – see your individual modem manual for detailed

explanations.

Figure 4-4 shows the DIP switches provided on the Antenna Side of the CRS-170A L-Band 1:1

Redundancy Switch (towards the BUC and LNB). Use these features to set the ‘Mode’ and

‘Switch Conditions’.

Note that the ‘Mode’ DIP switch labeling differs between the original and current (i.e., Rev. ‘A’

and later) versions of the CRS-170A.

On the next page, Table 4-1 details 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.
