FCC/DOC Compliance
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits
are designed to provide reasonable protection against harmful interference when the equipment is operated in a residential installation. This equipment
generates, uses, and can radiate radio frequency energy. If the equipment is not installed and used in accordance with the instructions, it may cause
harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation.
If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, try to
correct the interference as follows: reorient or relocate the affected device; increase the separation between this equipment and the affected device;
connect this equipment to an outlet on a circuit different from the circuit to which the affected device is connected; consult a dealer or an experienced
radio/television technician for help.
This Class B digital apparatus meets all requirements of the Canadian Interference-Causing Equipment Regulations. Cet appareil numérique de la
classe B respecte toutes les exigencies du Règlement sur le materiél brouilleur du Canada.
Warnings

personnel. Those who are familiar with servicing computers can follow instructions in a manual to service equipment, and do so without harm to
themselves or damage to the equipment.
Changes or modifications made to the system that are not approved by the party responsible for compliance could void the user's authority to operate
the equipment.
To reduce the risk of electrical shock, do not attempt to open the equipment unless instructed. Do not use a tool for purposes other than instructed.
There is a danger of explosion if the battery is incorrectly replaced. Replace the battery only with the same or equivalent type as recommended by the
manufacturer. Dispose of used batteries according to the manufacturer's instructions.
To comply with FCC Class B limits, you must use shielded cables with this device.
Notes

Chassis Feature Summary
The system’s galvanized metal chassis minimizes electromagnetic interference (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.
One externally accessible bay can hold up to six one-inch drives with the
small computer systems interface (SCSI) backplane, or up to two EIDE or
SCSI 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, advanced technology extended (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 accessible from the front of the system.
3.5-inch Hard Drive Bays
The system was designed to allow the user to install a Redundant Array of Independent Disks
(RAID). A hot-swap-capable backplane accommodates six RAID 3.5-inch-wide (1-inch high) hard
disk drives, which are accessed from the front of the system.
A drive carrier is required as part of the hot-swap implementation. The drives are mounted in the
carrier with four fasteners and the carrier snaps into the chassis. The 10 K rpm hard disk drives
with power exceeding 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 76.
• For information on how and when to install extra fans, see “Installing Fans for High-Power
Drives” on page 100.
A metal EMI shield and 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.
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. You should not use these bays for
hard disk drives because of inadequate cooling, and because they generate EMI which increases the
possibility of electrostatic discharge (ESD).

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. The chassis can
accept up to five more fans. 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.
