Power The 8620 BAC is available in an AC-powered version and a
DC-powered version.
The AC version can be connected to a DC source to provide power
redundancy. With the DC version, two separate DC sources may be
employed to provide power redundancy.
The AC version accepts AC power (100–240 V, nominal; 50–60 Hz) and
converts it to DC power. The maximum current draw is 4 amps, or
250 watts at 120 VAC.
The DC version operates from a DC 48 VDC power supply (48 V,
nominal). The maximum current draw is less than 5 amps at 42 VDC.
Both versions distribute 48 VDC power from the power source to
individual cards via the backplane.
Grounding A ground lug is located on the right rear of the 8620 BAC. It accepts 14
AWG wire.
A noninsulated banana jack is located at the left front of the 8620 BAC
providing a ground for the ESD wrist strap plug.
