Fig. 6.14.1. Adjustable jumpers on the NetGuardian circuit board
The following options are adjusted by resetting jumpers on the NetGuardian's circuit board:
· Control relays can be switched from normally open (N/O) to normally closed (N/C)
To simply configure the jumpers, use the hatch panel access on the top of the NetGuardian chassis. This allows
for easy access and configuration of jumpers without having to open the entire case. Remove top screw on hatch
panel and rotate hatch cover until you can easily reach the jumpers. Figure 6.14.1 shows the circuit board and the
location of the adjustable jumpers.
