Power Supply Modules
The SC862 has a set of 700W Triple Redundant Power Supply which
consists of three individual Power Supply Modules (SP352-TP p/n PWS-
026 or p/n PWS-026B for black bezels.)
continuous 700 watts of power to the system.
remaining two will automatically take up the load to keep the system
running. All three are hot-pluggable, allowing you to replace a failed
module without powering down the system.
modules also have an auto-switching capability, which enables them to
automatically sense and operate at any voltage level between 100 and
225 input volts.
Power Supply Failure
If any one of the three power modules fails, the remianing two modules
will assume the full load and enable the system to continue operating
without interruption. An audible alarm will notify you of a power module
failure, which you can disable by pressing the alarm switch on the
chassis control panel. The PWR Fail LED will also illuminate and remain
on until the failed module has been replaced.
Replacing Power Modules
1.
Identifying the failed power module:
Inspect the power modules mounted in the front of the chassis. The
module with the illuminated red LED has failed and should be replaced as
soon as possible. If the LED is neither red or green, check to make sure
all three power cables are all fully plugged into the back of the chassis.
If they are, the power module is probably bad.
2.
Removing a hot-plug power module: (See Figure 6-7)
You do not need to power down the system to replace a failed power
module. To remove a failed module, push the locking tab on the failed
module up, then grasp the handle and pull the module completely out.
You don't need to unplug the power cable from the back of the chassis.
3.
Installing a new hot-plug power unit:
Replace the failed unit with another unit of the same model: SP352-TP
(p/n PWS-026). Gently but firmly push the new unit all the way into the
open bay. Secure it by pushing the locking tab downward. The green
LED on the power supply unit should illuminate to show that it has power
and is operational.
