Power system with redundancy The 750 watt, 220 VAC autoranging power supplies include integrated
fans for cooling. When the server is configured with three supplies
(2 + 1), the third provides redundancy. The supplies can be replaced—
hot-swapped—without turning off server power. The server requires a
minimum of two power supplies. LEDs on the back of the power supply
indicate power on, failure, and predictive failure.
Server chassis The electrogalvanized metal used in manufacturing the server chassis
minimizes electromagnetic interference (EMI) and radio frequency
interference (RFI).
The peripheral bay provides the interface for 3.5- and 5.25-inch media.
It can support:
• One 5.25-inch IDE CD-ROM drive in the 5.25-inch half-height bay.
(Optional: any IDE or single-ended SCSI device, like a tape drive.)
• Two 3.5-inch wide by 1.0- or 1.6-inch hot-swappable low-voltage
differential SCSI (LVDS) hard disk drives mounted side-by-side in
the 3.5-inch hot-swapping bays. These bays allow hot-swapping of
hard disk drives without shutting down the server.
Ten hot-plug PCI I/O expansion slots (six 33 MHz PCI, four 100 MHz
PCI-X).
The plastic front bezel provides airflow and easy access to drives in the
hot-swapping bays. The removable top covers provide proper airflow
and easy access to components inside the server. Only technically
qualified personnel should remove the server covers.
Cooling system with redundancy Six fans (5 + 1) cool and circulate air through the server. The sixth fan
is redundant. The fans can be replaced—hot-swapped—without
turning off server power. An LED indicator mounted next to each fan
guarantees positive identification of the failed fan.
Integrated power supply fans—two or three—cool and circulate air
through the power supplies and the bottom of the chassis.
