Power Supply Units (PSUs)

PN: GAL-9273CPSU
The A16F-R2422 is equipped with two (2) redundant, hot-swappable, 460W
PSUs, which are located at the rear of the enclosure. (See
Figure 1-5
) The
PSU is permanently mounted into a 2U (dual-level) bracket especially
designed to house both the PSU and a cooling module, which is mounted in
the lower part of the 2U bracket. Hot-swapping the PSU requires the
removal of the cooling module.
As shown in
Figure 1-12
, each PSU comes with a single power socket for
power cord plug-in and a power switch on the right to turn the subsystem on
and off. Two (2) embedded cooling fans provide sufficient airflow to keep
the PSU cool. A single LED indicates the PSU status. When any power
supply failure occurs, such as over-voltage or fan failure, the LED shines
red. A handle at the back of the PSU enables you to remove the PSU from
the subsystem while the subsystem is online. This should only be done if the
PSU has failed and needs to be replaced.
A retention screw at the top of the PSU module secures the PSU to the
enclosure. To remove the PSU, the retention screw must be removed first.
When installing a new PSU module, make sure that the retention screw has
been firmly secured.
For the PSU specifications, please refer to
