1: Chassis Description
Chassis Features
The SGI 1450 server is designed to be either mounted in a standard 19-inch rack (rack
mode) or standing upright (pedestal mode). Table 1-1 shows the physical specifications
for the SGI 1450 server in rack mode.
For instructions on mounting the SGI 1450 server in a 19-inch rack, see the SGI 1450
Server Mounting Instructions.
Table 1-1 SGI 1450 Server Physical Specifications
Specification Rack Mode
Height 4u (7 inches)
Width 17.5 inches (44.5 cm)
Depth 26.5 inches (67.3 cm)
Weight 57 lbs. (26 kg), minimum configuration
88 lbs. (40 kg), maximum configuration
Required front clearance 3 inches (inlet air temperature <35 °C / 95 °F)
Required rear clearance 6 inches (no airflow restriction allowed)
Required side clearance 1 inch

1: Chassis Description
The chassis has two covers: a front cover and a top cover. The front cover is secured by
screws and should be removed only by a qualified service technician. The top cover is
secured by thumbscrews and provides user access to hot-pluggable PCI components.
Oneoftwothumbscrewsisnotedby“A”inFigure1-2.
Note: At this time, the Linux operating system does not support use of the PCI Hot-Plug
(PHP) feature. If you are running Linux, your system must be turned off before installing
or removing PCI boards. Windows 2000 requires drivers that are PHP compatible in
order to use the PHP feature.
Figure 1-2 Top Cover Thumbscrew
A bezel snaps on to the front of the chassis and allows adequate airflow to cool the system
components. The door in the bezel provides user access to hard drives and the peripheral
bay.
Figure 1-3 gives an overhead view of the system with the top cover, front cover, and front
bezel removed.

Warning: The total power requirement for the SGI 1450 server exceeds the 240 VA
energy hazard limit that defines an operator-accessible area. Only qualified service
technicians should access the processor, memory, power subsystem, and non
hot-plug/hot-swap areas of the baseboard.

1: Chassis Description
Table 1-2 summarizes the SGI 1450 server chassis features, using the labels provided in
Figure 1-3.
Table 1-2 Chassis Feature Summary
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 can only be accessed by qualified service
technicians.
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 replaced without
shutting down the server. This process is called hot-swapping.
Hot-swapping fans should only be performed by a qualified service
technician.
