1.7.2 Electrical
Table 1-6 lists the electrical specifications for the RES-21XR3.
1.7.2.1 System Power
The RES-21XR3 for X8SAX operates with two N+1 redundant AC power supplies
of 750-watts capacity each that auto-range single-phase AC input from 100 to 265
VAC (47 to 63 Hertz) sources. Filtered and fused (internal) AC is supplied to each
power supply from a rear-mounted power connection. Two
optional N+1 redundant
DC power supplies of 750 watts (48 volts) or 500 watts (28 volts) each may be sub-
stituted for the AC power supplies (see
Table 1-6 ). These supplies should be speci-
fied at the time of your order.
1.7.2.2 Output Voltage
The RES-21XR3 for X8SAX power supply provides output voltages that are split
b3.3V, +5V, +5Vsb, +12V, and -12V rails.
