Features
Power is drawn equally from all supplies present (one
or two power supplies). A system with one power supply
can be fully loaded (all drive bays and add-in board
slots filled). In a high-access system with two power
supplies, the second supply gives redundancy, because
the load is redistributed if one supply fails.
Server Security
The following subsections describe mechanical locks and
software locks via the BIOS Setup.
Mechanical Locks and Monitoring
Figure 2-6 shows the server mechanical locks and
monitoring.
