Power supplies
The enclosure has two removable power supplies
that provide power to the internal components. If one power supply malfunctions or
is turned off, the other power supply maintains electrical
power to the enclosure.
Note: To preserve the optimal
airflow, do not remove a failed power supply from the chassis
until you are ready to replace it with a new power supply.
Figure 1 shows the power supply controls, LEDs, and connectors.
