1 Chassis Description
The SC450NX MP server is designed to either stand upright (pedestal mode) or be mounted in a
rack (rack mode). Figures 1 and 2 show examples of these configurations. Before operation, you
must purchase an adapter kit to configure the server for one of the two modes. If you have already
created a pedestal server but now want to install it in a rack, you will also need an adapter kit.
If you have not already purchased a kit for your particular task, contact your customer service
representative for details. For instructions on mounting your server, see the printed
SC450NX MP Server System Rack/Pedestal Kit Installation Guide accompanying your kit.

Chassis Feature Summary
The system’s galvanized metal chassis minimizes EMI and radio frequency interference (RFI).
The removable access cover is attached to the chassis with two screws. A front subchassis and an
electronics bay (at the rear of the main chassis) both rotate outward and can be removed entirely to
provide easy access to internal components. The removable front panel provides access to the
3.5- and 5.25-inch peripheral bays in the front of the chassis.
Table 2. Chassis Feature Summary
Feature Description
Drives Installed:
1.44 MB, 3.5-inch diskette drive, accessible from front subchassis.
Expansion capacity:
Three 5.25-inch-wide bays that are externally accessible, designed to hold
half-height standard removable media devices; the bays can be converted
into a single full-height bay.
Also, one externally accessible bay can hold up to six one-inch drives with an
optional SCSI backplane, or up to two drives without the backplane.
Expansion slot covers Up to eight slot covers can be used; every slot opening that does not have an
add-in board installed must have a slot cover installed.
Baseboard Form-factor, 16 ×13 inches, ATX I/O.
Power supply Up to three 400-watt power supplies with integrated cooling fans and
detachable AC power cords.
Cooling Up to 11 fans provide cooling and airflow: three system fans inside the
chassis (and three more needed only for redundant cooling), one fan for each
power supply (up to three), and two fans for cooling hard drives.

Peripherals
3.5-inch Diskette Drive
The 3.5-inch diskette drive in the 3.5-inch peripheral bay supports 720 KB, and 1.44 MB media.
The drive is externally accessible from the front of the system.
3.5-inch Hard Drive Bays
The chassis contains one bay for two 3.5-inch-wide (1" high or 1-5/8" high) LVDS SCSI hard
drives with internal cabling. An optional hot-swap-capable backplane can accommodate six
3.5-inch-wide (1" high) or three 3.5-inch (1-7/8" high) hard drives, which are accessed externally
from the front of the system. To upgrade to a backplane, or to upgrade your existing backplane,
you must buy a kit.
As part of the hot-swap implementation, a drive carrier is required. The drives are mounted in the
carrier with four fasteners and the carrier snaps into the chassis. Drives whose power exceeds 15
watts require heatsinks and system fans for extra cooling. These parts are available in an optional
kit.
• For information on how and when to install heatsinks, see “Installing Heatsinks on High-
Power Drives” on page 82.
• For information on how and when to install extra fans, see “Installing Fans for High-Power
Drives” on page 106.
A single metal EMI shield and plastic door cover the drive bays. A hot-docking bay is provided
for drives that are 3.5 inches wide and 1 inch high. Drives can consume up to 22 watts of power
and must be specified to run at a maximum ambient temperature of 55 °C.
The system was designed to allow the user to install a Redundant Array of Independent Disks
(RAID). A software implementation with onboard SCSI or an add-in board can be used to set up
RAID applications.
5.25-inch Removable Media Device Bays
The chassis has three 5.25-inch half-height bays that are accessible from the front of the system.
These bays are intended to provide space for tape backup or other removable devices.
You can convert the 5.25-inch bays to a single full-height bay. We recommend that you do not use
these bays for hard disk drives, because they generate EMI (increasing ESD susceptibility), and
because of inadequate cooling.

17
Power Supplies
The chassis can be configured with one, two, or three 400-watt power supplies, each designed to
minimize EMI and RFI. Each supply operates within the following voltage ranges and is rated as
follows:
• 100-120 V∼at 50/60 Hertz (Hz); 7.6 A maximum
• 200-240 V∼at 50/60 Hz; 3.8 A maximum
The DC output voltages of each power supply are:
• +3.3 V at 36 A max
• +5 V at 24 A max (total combined output of +3.3 V and +5.5 V not to exceed 195 W)
• +12 V at 18.0 A with 19.0 A <10ms peak
• +24 V at 50mA
• -12 V at 0.5 A
• +5 V standby 1.5 A
Power is sourced through the power cable to the 20-pin main connectors on the baseboard.
Remote sensing signals are provided through the cable to the 14-pin auxiliary connector on the
baseboard.
System Cooling
The minimum chassis configuration includes three fans for cooling and airflow (and can accept up
to five more). The number of additional fans depends on your configuration: one fan for each
power supply (up to three) and two fans for cooling hard drives.
✏NOTE
The access cover must be on the system for proper cooling.
