4 Maintain Power Supply Units The array supports two hot-swappable power supply units. The array is capable of operating with one power supply temporarily, but both power supplies are required to maintain long-term reliability of the array. About Power Supplies The PS Series array receives power from two power supply units (PSUs). The array can run on one supply while the other is in a failed state. Each unit has a 2800W power supply that requires 200-240VAC high AC line power source. Identifying Power Supply Failures You can identify a power supply and cooling module failure by the following methods: • LEDs on the power supply and cooling modules. See Back-Panel Features and Indicators on page 5 for details. • Messages on the console, in the event log, or in the Group Manager GUI Alarms panel. • Group Manager GUI and CLI output. The GUI group member Enclosure tab or the CLI member select member_name show enclosure command shows a power supply and cooling module failure. Note: When viewing the rear of the array, power supply 0 is on the left and power supply 1 is on the right. Power Supply Controls and LEDs The power supplies contain LEDs that indicate their status. AC Power Supply Figure 22 illustrates the features of the power supply. Table 10 describes these features. Figure 22: 2800W Power Supply LEDs 31

About
Power
Supplies
The

array
receives
power
from
two

units
(PSUs).
The
array
can
run
on
one

while
the
other
is
in
a
failed
state.
Each
unit
has
a
2800W
power
supply
that
requires

Identifying
Power
Supply
Failures
You
can
identify
a
power
supply
and
cooling
module
failure
by
the
following
methods:
•
LEDs
on
the
power
supply
and
cooling
modules.
See
Back-Panel
Features
and
Indicators
on
page
5
for
details.
•
Messages
on
the
console,
in
the
event
log,
or
in
the
Group
Manager
GUI
Alarms
panel.
•
Group
Manager
GUI
and
CLI
output.
The
GUI
group
member
Enclosure
tab
or
the
CLI
member
select
member_name
show
enclosure
command
shows
a
power
supply
and
cooling
module
failure.
Note:
When
viewing
the
rear
of
the
array,
power
supply
0
is
on
the
left
and
power
supply
1
is
on
the
right.
