power supply operation. Insert the power supply card in chassis prior to applying power.
3.3.1. RSS-3
The RSS-3 chassis supports one internal power supply installed thru the rear of the chassis, or an external 24VDC
power power supply can also be used by installing the Power Accces Card 193xxx.
Redundant power can be added by connecting an external power supply to the DC power connector provided on
the control card.
LED indicators on the chassis front panel display the operating status of PS1 or PS2. The PS2 indicator only
functions when an external power supply is added for redundancy.
3.3.2. RSS-16 Power Supply Options
The RSS-16 can be configured for redundant power by using internal or external power supplies. Two internal
power supply cards can be installed in the single slot power supply position in any combination of AC and DC
models. The various configurations are shown below.
Insert the card into the desired power supply position from the rear of the chassis. PS1 is the top position and PS2
is the bottom position
A blank power card panel is included with the chassis when only one of the redundant supplies is installed. This
panel should be kept for future use when two supply cards are installed should the need for removal of one of the
supplies become necessary.
