The PSR2800-ACV can provide both system power and PoE power
outputs. The upper switch (callout (4) in Figure 1) is used to control
the output of the entire power supply system, while the lower switch
(callout (8) in Figure 1) is used to control the PoE power output.

CAUTION:
Turn off the PoE switch
if PoE power supply is not required by
the device
. For more information, see the installation guide or
hardware information and specifications for the device.
The PoE power can be used both for power supply of PoE-powered
devices and for auxiliary power supply of devices that do not support
PoE. For details, refer to the corresponding installation manuals.

Status LEDs
The PSR2800-ACV power module has five red/green status LEDs:
INPUT, OUTPUT, FAN, PoE INPUT, and PoE OUTPUT.
The PSR2800-ACV power module can provide PoE only when the
system power output is normal.
Table 3 describes the colors and working status of the five LEDs in
different cases.
Table 3 Description of LEDs on the PSR2800-ACV power
module
LED Color/
status Meaning
INPUT
Off No system power input is present.
Green The system power input is normal.
Red The system power input is abnormal.
OUTPUT
Off No system power input is present.
Green The system power output is normal.
Red
The power switch is in the OFF position.
Power alarm (output short circuit, output
over-current, output over-voltage, or
overheat occurred to the power module,
and the power module took a
self-protection action).

5
LED Color/
status Meaning
FAN
Off No system power input is present.
Green The power module fan works normally.
Red
The system switch is in the OFF position.
The power module fan is faulty (The power
module takes a self-protection action and
stops power output two seconds after the
fan fails).
PoE
INPUT
Off No PoE power input is present.
Green The PoE power input is normal.
Red The PoE power input is abnormal.
PoE
OUTPUT
Off No PoE power input is present.
Green The power output is normal.
Red
The power switch is in the OFF position.
Power alarm (output short circuit, output
over-current, output over-voltage, or
overheat occurred to the power module,
and the power module took a
self-protection action).
CAUTION:
Do not turn on
and off the power switch too frequently. After
turning off
the power switch, wait at least 30 seconds before
turning it on again.

Figure 4 Install/remove the PSR2800-ACV power module
Installing a Power Module
Follow these steps to install the PSR2800-ACV power module:
1. Put on an ESD-preventive wrist strap.
2. Take out the PSR2800-ACV power module out of its package.
3. With one hand grasping the handle of the power module and the
other holding the bottom, insert the power module along the
guide rails into the chassis until it snaps into the backplane
connector.

8
CAUTION:
•
You need to follow the forward inertia of the power module
when inserting it into the chassis.
•
To prevent damage to the connectors on the power module
and the backplane, first pull the power module out and then
insert it again in the case of any misalignment.
4. Tighten the captive screws with a No. 1 Phillips screwdriver to fix
the power module in the chassis.
CAUTION:
If the captive screws cannot be tightened, check whether the
power module is properly installed.
Removing a Power Module
Follow these steps to remove the PSR2800-ACV power module:
1. Put on an ESD-preventive wrist strap.
2. Loosen the captive screws on the power module with a No. 1
Phillips screwdriver.
3. With one hand grasping the handle of the power module, pull
the power module part way out of the chassis.
4. With this hand still grasping the handle and the other holding the
bottom, pull the power module slowly out of the chassis.
CAUTION:
Before removing the power module, disconnect the power
supply and remove the AC power cords.

Connecting and Disconnecting the AC Power
Cords
The following describes how to connect a power cable. To disconnect
a power cable, follow the inverse order.
When connecting and disconnecting power cables, check that the
power switch is in the OFF position.
Connecting the AC Power Cords
The following describes how to connect the system power cord. You
can connect the PoE power cord in the way you connect the system
power cord.
Figure 5 Connect the AC power cord
Follow these steps to connect the system power cord:
1. Use a No. 1 Phillips screwdriver to remove the screws from the
power cord retention clip and remove the upper part of the
power cord retention device.
2. Plug one end of the power cord shipped with the power module
into the system power socket, and then fix the removed part of
the power cord retention clip to the lower part to prevent a falloff.

10
3. Plug the other end into the AC power socket strip of the AC
mains.
CAUTION:
Since
typically 10 A busbars are available in the equipment
room
but the PSR2800-ACV power module requires a 16A
power cable (AC), you need to use a 16 A busbar.
