Internal Power Supply – SM261A-VAC
The SM261A-VAC is an internal power supply card that installs directly in the group switching chassis, occupying up to two slots. It provides robust, redundant power to all connected cards within the chassis. For fully redundant internal power, two of these cards are required, occupying a total of four slots.

External Power Adapter – SM261A-CARD
The SM261A-CARD enables power from external power supplies, designed to adjust one or two 12 VDC inputs, each delivering 5 A. The card indicates power status and supports redundancy by adding a second external power supply (SM961A-PS).
