2 Product Overview
2.1 Introduction
The RPS800-A is an external DC power supply
unit that uses AC input and provides DC output for
multiple switch and router models as a redundant
backup power supply system.
The RPS800-A supports cold backup of power
supply commonly, which means that the RPS800-A
only switches to the DC output state when it detects a
power supply failure of the powered device. When the
powered device’s own power supply system is

2
functioning, the RPS unit only works in the monitoring
mode, without feeding power to the powered device.
The output of the RPS800-A is controlled by a
control pin. When the powered device’s own power
supply system becomes fails, a LOW signal is sent to
the control pin of the RPS unit. Upon receiving this
LOW signal, the RPS unit switches to the DC output
state within 2 ms.
If using the same AC power source with the
powered device, the RPS800-A can timely provide DC
supply to the powered device when the internal power
supply system of the powered device fails.
If using a different AC power source from the
powered device, the RPS800-A can timely provide DC
supply to the powered device when the AC power
source to the device fails, thus ensuring uninterrupted
operation of the device.

3
Note:
For some models of powered devices, the control
pin of the RPS800-A can be controlled through a
special cable to support hot backup of power
supply. Namely, when the power supply systems
of the powered devices operate normally, the
RPS unit also provides part of the power feed to
the devices; when the power supply system of a
powered device fails, the RPS unit becomes an
independent power supply system to feed that
powered device.
2.2 Features
The RPS800-A can provide selective DC outputs.
Depending on the connected DC output cable(s), the
RPS unit can provide +12 VDC or –54 VDC power
supply to the powered device, or +12 VDC and –54
VDC outputs concurrently to the powered device.
Note:
As optional parts for the RPS800-A, different
types DC output cables are available depending
on the requirement of the powered device. For
details about the DC output cables, please
consult H3C marketing or customer service staff.

3.1 Precautions
To avoid any device impairment or bodily injury
because of improper use, follow the precautions listed
below:
zDo not place the RPS unit on an unstable
case or tabletop, and ensure that the cabinet
and the workbench are firm enough to
support the RPS unit and its accessories.
zMake sure that the ventilation and heat
dissipation systems of the cabinet and the
table-top are good. Make sure that enough
room is left around the air intake and outlet of
the RPS unit to allow good heat dissipation.
zThis RPS unit is designed for indoor use only.
Make sure that the temperature in the
equipment room is within the range of 0to
45(32to 113), and the humidity within
the range of 10% to 90%.
zKeep the RPS unit away from any heavy-duty
radio transmitter, radar transmitter, and
high-frequency devices working in high
current. Take electromagnetic shielding
measures if necessary.
zUse a single-phase three-wire power socket
with a neutral point connector or a

8
multi-functional power socket for computers.
Make sure that the neutral point of the power
source is well grounded.
zMake sure that the power source satisfies the
voltage requirement of the RPS unit.
zInterface cables must be routed indoors.
Otherwise, over-voltage and over-current
may damage the device. As for power cables
from the outside of the building, you may add
a dedicated lightening arrester at the input
end of the cable.
zTo enhance lightening protection, you may
need to add a power lightening arrester at the
input end.
zWear an ESD-preventive wrist strap when
installing the RPS unit, and make sure that
the wrist strap has good skin contact.
zTo avoid electric shock, NEVER open the
chassis of the RPS unit while it is in operation;
try not to open the RPS unit even if it is not
electrified.
zUnplug the power cord before cleaning the
RPS unit.
zKeep the equipment room clean. The limits on
the concentrations of dust and harmful gases
in the equipment room are shown in the
following tables:

3.2 Installing the RPS Unit
The RPS800-A can be installed either in a
19-inch standard rack or directly on a tabletop.

10
3.2.1 Installing the RPS Unit to a 19-inch
Rack
Caution:
The front mounting ears are used only for fixing
the RPS unit to the rack; they cannot bear the
weight of the RPS unit. When installing the
RPS800-A to a 19-inch rack, be sure to use a tray
or bracket to support the weight of the unit.
Step 1: Put on an ESD-preventive wrist strap and
check the grounding and stableness of the rack.
Step 2: Fix the supporting tray supplied with the
rack horizontally at the appropriate position of the
rack.
Step 3: Attach the front ears to the front end of the
RPS unit using screws, as shown in Figure 3 .
Figure 3 Install the RPS unit to a 19-inch rack (1)

11
Step 4: Place the RPS unit horizontally on the
supporting tray, gently push the unit into the rack
along the supporting tray, and fix the mounting ears to
the front square-holed brackets of the rack with
screws and cage nuts, as shown in Figure 4 .

3.2.2 Installing the RPS Unit on a Tabletop
If a 19-inch standard rack is not available, you
can place the RPS unit directly on a clean, stable
tabletop.
Follow these steps to install the RPS unit on a
tabletop:
Step 1: Cautiously turn the RPS unit upside down.
Then, use a piece of dry, soft cloth to remove any oil
stain or dust from the dents on the bottom of the
chassis.

12
Step 2: Peel off the stickers on the supplied foot
pads and paste the foot pads into the dents on the
chassis bottom.
Step 3: Turn over the RPS unit and place it on the
tabletop. Verify the stableness and good grounding of
the table.
3.3 Connecting the RPS Unit to the
Powered Device
The RPS800-A can be used as a redundant
backup power supply unit for multiple switch and
router models. The following describes how to
connect the RPS unit to a switch.
(1) RPS AC input (2) RPS rear panel
(3) RPS DC output (4) DC power cable (optional)
(5) Switch redundant power supply input
(6) Switch rear panel (7) Switch AC input
Figure 5 Connect the RPS unit to a switch

13
Step 1: Check that the power source to the RPS
unit is disconnected.
Step 2: Remove the blank panel covering the
redundancy power supply input of the switch.
Step 3: Plug one end of the RPS DC output cable
into the redundant power supply socket on the rear
panel of the switch and the other end into the DC
output socket of the RPS unit.
Step 4: Connect the AC power source to the RPS
unit.
Step 5: Check that the PWR LED on the front
panel of the RPS unit lights up.
Note:
The OUT LED lights up only when the RPS800-A
switches to the DC output state. When the
RPS800-A works in the monitoring mode, its OUT
LED stays off.
