Chapter 1 Server Description
Diskette Write Protection
If the protection feature is enabled with the SCU, diskette writes are
disabled when the system is in the secure mode. Diskette write protection is
only in effect while the system is in the secure mode. Otherwise, write
protection is disabled.
Video Blanking
If enabled with the setup or SCU, the video screen goes blank when the
system is in secure mode.
Power System
The power system in the server may be configured with one, two, or three
360 watt power supplies.
The 360 watt power supply provides sufficient power for an entry level
server. The power supply accepts these input voltage ranges:
•
100-120 VAC at 50/60 Hertz (Hz); 7.7 A maximum current
•
200-240 VAC at 50/60 Hz; 4.4 A maximum current
If a single power supply fails in a redundant power system, the yellow
power supply failure LED on the front panel starts flashing. You can swap
out the faulty supply without shutting down the server.
Server Cooling
Two blowers inside the chassis provide cooling for the processors, memory
modules, and add-in boards. Two more fans may be installed for
redundant cooling. If a fan or blower fails, the server management
subsystem notifies the system board and turns on an LED on the front
panel.
A system with only one power supply includes an auxiliary fan to provide
cooling for the hard drives. A system with multiple power supplies
provides enough cooling without an auxiliary fan.
