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 module. In the
case of output short circuit, or abnormal temperature, the power
module will resume normal operation automatically when the
fault is cleared
. However,
if the power alarm is caused by output
over
-voltage, the power module will get locked up and will not
resume operation automatically. In this case, turn off the power
switch
, disconnect the power cables, and then reconnect the
power cable and turn on the power switch.
Status LEDs of the PSR1400-D
The PSR1400-D has four red/green status LEDs, which indicate the
input and output statuses of the power module and the working
status of the power module fan, respectively.
The PSR1400-D can provide PoE only when the system power
output is normal.

Figure 5 Install/remove a PSR1400-D power module
Installing a Power Module
1. Wear an ESD-preventive wrist strap and take a new power
module out of its package. Check that the input mode of the
power module 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:
You need to follow the forward inertia of the power module when
plugging it into the chassis.
To prevent damage to the power
module 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.

11
3. Tighten the captive screws with a No. 1 Phillips screwdriver.
CAUTION:
If the captive screws cannot be tightened, ch
eck whether the
power module is properly installed.
Removing a Power Module
Remove a power module in the opposite way you install it:
1. Wear an ESD-preventive wrist strap and loosen the captive
screws on the power module.
2. Grasp the handle of the power module 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 module is heavy, you are recommended to
grasp the power module handle with one hand and hold the
bottom with the other while pulling out a power module slowly.
Connecting and Disconnecting the Power
Cables
The following describes how to connect a power cable. To disconnect
a power cable, follow the inverse order.
When connecting and disconnecting a power cable, check that:
•
The power switch is in the OFF position.
•
In the case of a DC power module, make sure that the power
switch at the other end of the DC power cables is also in the
OFF position to avoid danger.

12
Connecting the AC Power Cord
Figure 6 Connect the AC power cord
1. Use a No. 1 Phillips screwdriver to screw off the right part of the
power cable retention clip.
2. Plug one end of the power cable shipped with the clip into the
power socket and fasten the right part of the power cable
retention clip to the other part to lock the power cable.
3. Plug the other end into the AC power socket strip of the AC
mains.
CAUTION:
Since
typically 10 A busbars are available in equipment rooms
but the
PSR1400-A
power module requires a 16 A power cable
(AC), you need to use a 16 A busbar.

13
Connecting the DC Power Cables
