5.3.4
Redundancy load module, setting the load DIP switches
Detail of the DIP switch positions are given in section 5.3.3. If you wish to activate any of the resistive loads follow the sequence below.
1.
Calculate the additional load required, see section 5.1.1., 5.2 and 5.3
2.
Round this load up to the nearest three watt step
3.
Switch the appropriate number of DIP switches of SW5 to the ON position
Note. If sufficient load is not applied, it is possible for a PSU front panel power LED to be
GREEN
and the “power good” output to be LOW
(alarm state), in this case the power supply will not be registered by the
ViaLiteHD
summary alarm and SNMP and web controller cards.
5.3.5
Redundancy load module, using with SNMP and controller module
The redundancy load module is not fitted with a micro controller or I2C memory, so it is not visible on the ViaLiteHD controller GUI or
accessible via SNMP.
