Features
Power System
The system may be configured with two, three, or four
330 Watt power supplies. Each supply automatically
switches between these input voltage ranges:
■
100-120 VAC at 50/60 Hz; 10 A maximum current
■
200-240 VAC at 50/60 Hz; 5 A maximum current
■
The AC input connector is a panel mounted, IEC
320/C20 type connector.
Each supply has the following:
■
Two cooling fans integral with each power supply
enclosure. The fan circuitry implements fan failure
detection.
■
Two indicators: power and alarm.
Number of Power Supplies in a Configuration
In a system, power is drawn equally from all supplies
present (from two to three to four). In a high-access
system with three or four power supplies, the power
supply in the redundant position (R) 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 Utility.
Mechanical Locks and Monitoring
Figure 2-8 shows the server mechanical locks and
monitoring.
