6-4 Power Supply
The SC747 chassis has a 1400W (redundant) power supply. This power supply
is auto-switching capable. This enables it to automatically sense and operate at a
100v to 240v input voltage. An amber light will be illuminated on the power supply
when the power is off. An illuminated green light indicates that the power supply
is operating.
Power Supply Failure
If the power supply module fails, the system will shut down and you will need to
replace the module. Replacements can be ordered directly from Supermicro (see
contact information in the Preface).
As there is only one power supply module in the system, power must be com-
pletely removed from the server before removing and replacing the power supply
for whatever reason.
Replacing the Power Supply
With a redundant power supply, the system automatically switches to the second
power supply if the fi rst should fail.
Replacing the Power Supply
Power down the chassis and unplug the power cord. If your chassis includes 1.
a redundant power supply (at least two power modules), you can leave the
server running and remove only one power supply.
Push the release tab (on the back of the power supply) as illustrated in Figure 2.
6-5.
Pull the power supply out using the handle provided.3.
Replace the failed power module with the same model.4.
Push the new power supply module into the power bay until you hear a click. 5.
Plug the AC power cord back into the module and power up the server.6.
