Introduction
The PSR650-A(JC492A) is a built-in power supply with AC input and
DC output while the PSR650-D (JC493A) is a built-in power supply
with DC input and DC output. These two power supply models can
transfer the input voltage into 12 V or 3.3 V needed by the device.
Table 1 Features of the PSR650-A and PSR650-D power
supplies
Feature Description
Protection
functions
Support input under-voltage protection,
output over-voltage protection, short-circuit
protection, and overheat protection
Hot swap support Support hot swap while the device is in
operation
1+1 hot backup
support Support 1 + 1 hot backup and current
sharing
CAUTION:
For a device that supports both AC and DC inputs, you can
choose either of the two types of power supplies as needed, but
do not use different types of power supplies in the same device.

Storage
temperature -40°C to +70°C (-40°F to
+158°F)
Status LED
The PSR650-A and PSR650-D have only one status LED. Table 3
describes its colors and working status.

Table 3 Description of LEDs on the PSR650-A and PSR650-D
Color/status Meaning Possible causes
Green The power
supply is
operational. —
Red The power
supply is
faulty.
Power alarm (input
under-voltage, output short
circuit, output over-current,
output over-voltage, or
overheat occurred to the power
supply, and the power supply
took a self-protection action).
The power supply fan is faulty.
OFF The power
input is faulty.
The power switch is off.
The power cord is connected
incorrectly.
CAUTION:
In case of a power alarm (the OUTPUT LED turns red), check
whether output short circuit, output over-current, output
over-voltage, or overheat occurred to the power supply. In the
case of output short circuit, or abnormal temperature, the powe
r
supply will resume normal operation automatically when the
fault is cleared. However, if the power alarm is caused by output
over-voltage, the power supply will get locked up and will not
resume operation automatically. In this case, turn off the power
switch, disconnect the power cord, and then reconnect the
power cord and turn on the power switch.
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.

Power supply Installation and
Removal
When installing or removing a power supply, be sure to follow the
sequence shown in Figure 3 or Figure 4.
Figure 3 Flow chart for installing a power supply
Figure 4 Flow chart for removing a power supply
Installing and Removing a Power supply
This section describes how to install and remove a PSR650-Apower
supply. You can install and remove a PSR650-D power supply in a
similar way.
You need to prepare the tools that you need to use to install or
remove power supplies.
WARNING!
When installing or removing a power supply, make sure that the
power switch is in the OFF position and no power cord is
connected to the power supply.

Figure 5 Install/remove a PSR650-A power supply
Installing a power supply
1. Wear an ESD-preventive wrist strap and take a new power
supply out of its package. Check that the input mode of the
power supply is correct.
2. Grasp the handle of the module with one hand and hold the
module bottom with the other. Slide the module slowly along the
guide rails into the chassis until it snaps into the chassis
backplane.
NOTE:
To prevent damage to the power supply and the connection
terminals on the backplane, make sure to pull the module out
first in case of any misalignment, and then push it in again.
3. Tighten the captive screws with a number No. 2 Philips
screwdriver.
7
CAUTION:
If the captive screws cannot be tightened, check whether the
power supply is properly installed.
Removing a power supply
Remove a power supply in the opposite way you install it:
1. Wear an ESD-preventive wrist strap and loosen the captive
screws on the power supply.
2. Grasp the handle of the power supply with one hand to pull out a
part of it. Then hold the module bottom with the other hand and
take out the module slowly.
CAUTION:
Since the power supply is heavy, you are recommended to
grasp the power supply handle with one hand and hold the
bottom with the other while pulling out a power supply slowly.
Connecting the power cord
After installing the power supply to the device, you can connect the
power cord. When connecting the power cord, check that:
•The power switch is in the OFF position.
•In the case of a DC power supply, make sure that the power
switch at the other end of the DC power cord is also in the OFF
position to avoid danger.
