An internal bay is provided for drives that are 3.5 inches wide and either 1 inch or 1.6 inches high. The
possible combinations (height and quantity) are as follows:
•Up to a total of six drives, each 1 inch high
•Up to a total of three drives, each 1.6 inches high
•Up to a total of four drives, two that are 1.6 inches high plus two that are 1 inch high
The side cover provides easy access to drives in the internal bay. The bay swings out and can be
removed.
Drives can consume up to 11 watts of power. Drives must be specified to run at a maximum ambient
temperature of 50 °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.
([WHUQDO%D\VIRULQFK5HPRYDEOH0HGLD'HYLFHV
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. As shipped, a CD-ROM
drive may be installed in the top of the three bays.
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, ESD susceptibility increases, and the drive will not
be adequately cooled.
3RZHU6XSSO\
Your chassis includes either a 300 watt or a 275 watt power supply
:DWW3RZHU6XSSO\
The 300 watt universal-type power supply is designed to minimize EMI and RFI. The supply operates
within the following voltage ranges and is rated as follows:
•100-120 V∼at 50/60 Hertz (Hz); 4.6 A maximum
•200-240 V∼at 50/60 Hz; 2.3 A maximum
The DC output voltages of the power supply are +5 V, +12 V, +3.3 V, -5 V, -12 V, and +5 V standby.
Power to the server board is provided through the power cable to the 24-pin main power connector. The
Auxiliary power connector provides the interface to the IMB bus and sensing signals for the Baseboard
Management Controller on the server board. Through this interface, LANDesk® Server Manager can
monitor the power supply.
6\VWHP&RROLQJ
The chassis includes two fans for cooling and airflow. One of these is the integrated fan in the power

To help prevent unauthorized entry or use of the system, the chassis includes a physical padlock loop and
a chassis intrusion switch that can be monitored by Server Management software.
6HFXULW\ZLWK0HFKDQLFDO/RFNVDQG0RQLWRULQJ
Secure the side cover to the chassis by inserting a padlock (not provided) through the metal loop
protruding through the slot in the back edge of the side cover.
•A padlock loop on the rear of the system side cover can be used to prevent access to the
microprocessors, memory, and add-in cards. A variety of lock sizes can be
accommodated by the .300 diameter loop.
Activate the side cover intrusion alarm switch. When the side door is opened, the switch transmits an
alarm signal to the server board, where server management software processes the signal. The system
can be programmed to respond to an intrusion by powering down or by locking the keyboard, for example.

Before removing the system side cover to work inside the system, observe these safety guidelines.
1. Turn all peripheral devices connected to the system off.
2. Turn the system off by using the push-button on / off power switch on the front of the
system. Then unplug the AC power cord from the system or wall outlet.
3. Label and disconnect all peripheral cables and all telecommunication lines connected
to I/O connectors or ports on the back of the system.
4. Provide some electrostatic discharge (ESD) protection by wearing an anti-static wrist
strap attached to chassis ground of the system—any unpainted metal surface—when
handling components.
:DUQLQJVDQG&DXWLRQV
These warnings and cautions apply whenever you remove the side cover of the system to access
components inside the system. Only a Micron technically qualified person should integrate and configure
the system.
WARNINGS
SYSTEM POWER ON / OFF: The on/off button (a convex button) on the
front panel DOES NOT turn the system AC power OFF. To remove
power completely from system, you must unplug the AC power cord
from the wall outlet or the system.
HAZARDOUS CONDITIONS, POWER SUPPLY: Hazardous voltage, current,
and energy levels are present inside the power supply. There are NO
user serviceable parts inside it; servicing should be done by technically
qualified personnel.
HAZARDOUS CONDITIONS, DEVICES AND CABLES: Hazardous electrical
conditions may be present on power, telephone, and communication
cables. Turn the system OFF and disconnect the power cords,
telecommunications systems, networks, and modems attached to the
system before opening it. Otherwise, personal injury or equipment
damage can result.

CAUTIONS
Electrostatic discharge (ESD) and ESD protection: ESD can
damage disk drives, boards, and other parts. We recommend that you do all
procedures in this chapter only at an ESD workstation. If one is NOT
available, provide some ESD protection by wearing an antistatic wrist strap
attached to chassis groundany unpainted metal surfaceon your system
when handling parts.
ESD and Handling Boards: Always handle boards carefully. They can
be extremely sensitive to ESD. Hold boards only by their edges. After
removing a board from its protective wrapper or from the system, place it
component-side up on a grounded, static-free surface. If you place the
server board on a conductive surface, the battery leads may short out. If
they do, this will result in a loss of CMOS data and will drain the battery.
Use a conductive foam pad if available but not the board wrapper. Do NOT
slide board over any surface.
Cooling and Airflow: For proper cooling and airflow, always install the
chassis side cover before turning on the system. Operating it without the
cover in place can damage system parts.

You need to remove the system side cover and in some cases the front cover to gain access to
components inside the system.
1. Observe the safety and ESD precautions at the beginning of this chapter.
2. Turn all peripheral devices connected to the system off.
3. Turn the system off by using the power on/off switch on the front panel, AND unplug
the AC power cord.
4. Label and disconnect all peripheral cables attached to the I/O panel on the back of the
system.
5. If there is a padlock installed on the back of the system, unlock and remove it.
6. Remove and save the three screws from the side cover; you will need them later to
reattach the cover.
7. Place the fingertips of your left hand under the built-in handle on the back of the cover.
8. Using an even pull, slide the cover backward, about an inch, until it stops.
9. Using your left hand, pull the back end of the cover toward you to disengage its
bottom row of tabs from the notches in the chassis.
10. Using both hands, lift the cover upward to disengage the top row of tabs from the
notches in the top edge of the chassis. Set the cover aside.

CAUTION
Do NOT damage EMI strips: When installing the side cover, Do NOT
damage the EMI gaskets mounted on the cover. Replace any damaged
strips, or the system may NOT meet EMI requirements.
1. Before replacing a side cover, check that you have not left loose tools or parts inside
the system.
2. Check that cables, add-in boards, and other components are properly installed.
3. Position the cover over the chassis so that the top row of tabs aligns with slots in the
top of the chassis. Slide the cover toward the front of the system until the cover tabs
firmly engage in the chassis.
4. Attach the cover to the chassis with the three screws you removed earlier, and tighten
them firmly.
