Table 1-7 lists the electrical specifications for the RES-XR4-1U.
1.8.2.1 System Power
The RES-XR4-1U operates with two N+1 redundant power supplies of 750-watts
capacity each that auto-range single-phase AC input from 100 to 240 Vac (47 to 63
Hertz) sources. Filtered and fused (internal) AC is supplied to each power supply
from a rear-mounted power connection. In the event the system is ordered with a sin-
gle power supply, a dummy/blank power supply will occupy the other bay, and in
such configuration, there is no redundancy in the power supply subsystem.
