Feature Description
A.Peripheral Bay
[A1 and A2]
A peripheral bay in the front of the system has a 5.25-inch device bay
and a media bay.
A1. Peripheral Bay:
Device Bay The device bay can hold a 5.25-inch CD-ROM or DAT device.
A2. Peripheral Bay:
Media Bay The media bay holds a 0.5-inch slim-line floppy drive and a 0.5-inch
slim-line CD-ROM drive.
B. Hard Drives The hard drive bay supports up to five 1.0-inch hot-swap Ultra 160
SCSI hard drives.
If the operating system supports hot-swapping of hard drives, these
drives can be changed without shutting down the server.
C. Power Subsystem Installed:
A power subsystem bay that supports up to three 350-watt power
supply modules in a (2+1) redundant configuration.
The power subsystem bay is mounted at the front-left corner of the
chassis and is shipped with three power supply modules.
Each power supply can be changed without shutting down the server.
D. Cooling Installed:
Fan board assembly and six fans in a redundant (5+1) fan array. The
fans cool the baseboard and other components.
In a 5+1 configuration, a failed fan may be removed and installed
without shutting down the server. This process is called
hot-swapping. Hot-swapping fans can only be performed by a
qualified service technician.
