Chapter 1: Introduction
The S12F-R1432 is equipped with two (2) 530W PSUs (
Figure 1-18
),
while S12F-G1433 is equipped with two (3) 350W PSUs (
Figure 1-
19
). The redundant, hot-swappable PSU modules are located at the
rear of the enclosure. The PSU is permanently mounted into a 2U
canister especially designed to house both the PSU and a cooling
module. If a PSU is removed from the chassis, the cooling module
within is also removed.
Each PSU comes with a single power socket for power cord plug-in
and a power switch to turn the subsystem on and off. A single LED
indicates the PSU status. If a PSU fails the LED lights steadily red.
An ejection handle on the PSU enables you to remove or to secure
the PSU in place. This should only occur if the PSU fails and needs
to be replaced.
In addition to the ejection lever, a retention screw fastened through a
hole on the extraction handle helps prevent accidental disconnection.
For the PSU specifications, please refer to
