Connecting the Power Cable
Connect the system's power cable to the system and, if a monitor is used,
connect the monitor's power cable to the monitor.
Securing the Power Cable
Bend the system power cable into a loop, as shown in the illustration,
and attach to the cable clasp.
Plug the other end of the power cable into a grounded electrical outlet or a
separate power source such as an uninterruptible power supply (UPS) or a
power distribution unit (PDU).
NOTE:
Ensure that the system is connected to a stand-alone power source with
stable power supply for better performance.
