INNPM11 NETWORK PROCESSING MODULE CONFIGURATION

3 - 9
The NPM module supports the warm failover feature which is
the ability to switch from the primary process control unit
interface to the redundant backup process control unit with-
out losing any information or functionality. An NKMP01 or
NKMP11 cable is required for redundant module operations.
For optimum warm failover performance, the NIS module firm-
ware revision should be E.0 or later. In redundant NPM module
applications, the dipswitches on the primary and backup NPM
module must be set identically except for the module address
setting, which must be unique. Configure the NPM module as
follows.
Dipswitch SW3 - Operating Modes
Dipswitch SW3 is an eight-pole dipswitch that determines the
operating modes and Controlway address of the NPM module.
Table
lists dipswitch SW3 settings. Record the dipswitch
SW3 settings in the space provided.
