Important Safety Information
Before installing this product, read the Important Safety Information document provided.
Power up
Observe the following guidelines before powering up the MDS600:
•Always install all components of the MDS600.
•Install hard drives in the MDS600 so the connected host controller can identify and configure them at
power up.
•Always power up the MDS600 first, and then the server blade.
To power up the MDS600:
1. Complete server blade hardware installation and cabling. See the server blade documentation.
2. Connect the SAS cables and power cords to the MDS600.
3. Press and hold the Power On/Standby button.
Wait and observe the system power LED and system fans. When the MDS600 powers up, the
system power LED illuminates solid green and the system fans spin to a high speed, and then spin
down to a low speed.
4. Power up the server blades. See the server blade documentation.
Power down
Be sure that the partner server blades are the first units to be powered down and the last to be powered
back up. Taking this precaution ensures that the system and the OS are shut down in an orderly manner.
IMPORTANT: If installing a hot-plug device, it is not necessary to power down the MDS600.
To power down the MDS600:
1. Power down the partner server blades. See the server blade documentation.
2. Press and hold the Power On/Standby button for approximately 4 seconds. This action powers
down both hard drive drawers.

Setup 14
Setup
Space and airflow requirements
To allow for servicing and adequate airflow, observe the following space and airflow requirements when
deciding where to install a rack:
•Leave a minimum clearance of 63.5 cm (25.0 in) in front of the rack.
•Leave a minimum clearance of 76.2 cm (30.0 in) behind the rack.
•Leave a minimum clearance of 121.9 cm (48.0 in) from the back of the rack to the back of another
rack or row of racks.
HP MDS600s draw in cool air through the front door and expel warm air through the rear door.
Therefore, the front and rear rack doors must be adequately ventilated to allow ambient room air to enter
the cabinet, and the rear door must be adequately ventilated to allow the warm air to escape from the
cabinet.
CAUTION: To prevent improper cooling and damage to the equipment, do not block the
ventilation openings.
When a vertical space in the rack is not filled by a server or rack component, the gaps between the
components cause changes in airflow through the rack and across the servers. Cover all gaps with
blanking panels to maintain proper airflow.
CAUTION: Always use blanking panels to fill empty vertical spaces in the rack. This
arrangement ensures proper airflow. Using a rack without blanking panels results in improper
cooling that can lead to thermal damage.
The 9000 and 10000 Series racks provide proper server cooling from flow-through perforations in the
front and rear doors that provide 64 percent open area for ventilation.
CAUTION: If a third-party rack is used, observe the following additional requirements to
ensure adequate airflow and to prevent damage to the equipment:
•Front and rear doors—If the 42U rack includes closing front and rear doors, you must
allow 5,350 sq cm (830 sq in) of holes evenly distributed from top to bottom to permit
adequate airflow (equivalent to the required 64 percent open area for ventilation).
•Side—The clearance between the installed rack component and the side panels of the rack
must be a minimum of 7 cm (2.75 in).
Temperature requirements
To ensure continued safe and reliable equipment operation, install or position the MDS600 in a well-
ventilated, climate-controlled environment.
The maximum TMRA for most MDS600 products is 35°C (95°F). The temperature in the room where the
rack is located must not exceed 35°C (95°F).

Setup 15
CAUTION: To reduce the risk of damage to the equipment when installing third-party options:
•Do not permit optional equipment to impede airflow around the MDS600 or to increase
the internal rack temperature beyond the maximum allowable limits.
•Do not exceed the manufacturer’s TMRA.
Power requirements
Installation of this equipment must comply with local and regional electrical regulations governing the
installation of IT equipment by licensed electricians. This equipment is designed to operate in installations
covered by NFPA 70, 1999 Edition (National Electric Code) and NFPA-75, 1992 (code for Protection of
Electronic Computer/Data Processing Equipment). For electrical power ratings on options, refer to the
product rating label or the user documentation supplied with that option.
WARNING: To reduce the risk of personal injury, fire, or damage to the equipment, do not
overload the AC supply branch circuit that provides power to the rack. Consult the electrical
authority having jurisdiction over wiring and installation requirements of your facility.
CAUTION: Protect the MDS600 from power fluctuations and temporary interruptions with a
regulating UPS. This device protects the hardware from damage caused by power surges and
voltage spikes and keeps the MDS600 in operation during a power failure.
When installing more than one MDS600, you may need to use additional power distribution devices to
safely provide power to all devices. Observe the following guidelines:
•Balance the MDS600 power load between available AC supply branch circuits.
•Do not allow the overall system AC current load to exceed 80 percent of the branch circuit AC
current rating.
•Do not use common power outlet strips for this equipment.
•Provide a separate electrical circuit for each power supply in the MDS600.
Electrical grounding requirements
The MDS600 must be grounded properly for proper operation and safety. In the United States, you must
install the equipment in accordance with NFPA 70, 1999 Edition (National Electric Code), Article 250,
as well as any local and regional building codes. In Canada, you must install the equipment in
accordance with Canadian Standards Association, CSA C22.1, Canadian Electrical Code. In all other
countries, you must install the equipment in accordance with any regional or national electrical wiring
codes, such as the International Electrotechnical Commission (IEC) Code 364, parts 1 through 7.
Furthermore, you must be sure that all power distribution devices used in the installation, such as branch
wiring and receptacles, are listed or certified grounding-type devices.
Because of the high ground-leakage currents associated with multiple MDS600 connected to the same
power source, HP recommends the use of a power distribution unit (PDU) that is either permanently wired
to the building’s branch circuit or includes a nondetachable cord that is wired to an industrial-style plug.
NEMA locking-style plugs or those complying with IEC 60309 are considered suitable for this purpose.
Using common power outlet strips for the MDS600 is not recommended.

Rack warnings
WARNING: To reduce the risk of personal injury or damage to the equipment, be sure that:
•The leveling jacks are extended to the floor.
•The full weight of the rack rests on the leveling jacks.
•The stabilizing feet are attached to the rack if it is a single-rack installation.
•The racks are coupled together in multiple-rack installations.
•Only one component is extended at a time. A rack may become unstable if more than one
component is extended for any reason.
WARNING: To reduce the risk of personal injury or equipment damage when unloading a
rack:
•At least two people are needed to safely unload the rack from the pallet. An empty 42U
rack can weigh as much as 115 kg (253 lb), can stand more than 2.1 m (7 ft) tall, and
may become unstable when being moved on its casters.
•Never stand in front of the rack when it is rolling down the ramp from the pallet. Always
handle the rack from both sides.
Site requirements
Select an installation site that meets the detailed installation site requirements described in the user guide
on the Documentation CD.
Installing the enclosure
WARNING: The storage array with no drives installed weighs 72.58 kg (160.00 lb). With
all drives and components installed, the storage array can weigh up to 145.15 kg (320 lb).
Before configuring your rack solution, be sure to check the manufacturer weight limits and
specifications. Failure to do so can result in physical injury or damage to the equipment and
the facility.
CAUTION: Always plan the rack installation so that the heaviest item is on the bottom of the
rack. Install the heaviest item first, and continue to populate the rack from the bottom to the
top.
NOTE: If you are installing more than one HP MDS600 Disk System, install the first HP
MDS600 Disk System in the bottom of the rack, and then install additional HP MDS600 Disk
Systems by moving up the rack with each subsequent HP MDS600 Disk System. Plan rack
installation carefully because it is difficult to change the location of components after they are
installed.
The rack rails are marked for easy identification. The left rack rail is marked "L" and the right rack rail is
marked "R."
To install the rack rails:
1. Begin with the left rack rail. Align the end of the rail with the rear rack column.

Setup 17
2. Slide the rack rail closed until the end of the rail is locked in place, wrapping behind the rear rack
column.
3. Slide the front end of the rail to the rack front column. When fully seated, the rack rail will lock into
place.
4. Repeat the procedure for the right rack rail.
WARNING: The HP MDS600 Disk System is very heavy. To reduce the risk of personal injury
or damage to the equipment:
•Observe local occupational health and safety requirements and guidelines for manual
material handling.
•Remove all installed HP MDS600 Disk System components from their HP MDS600 Disk
Systems before installing or moving the HP MDS600 Disk Systems.
•Use caution and get help to lift and stabilize HP MDS600 Disk Systems during installation
or removal, especially when the HP MDS600 Disk System is not fastened to the rack.
WARNING: Always use at least two people to lift an enclosure into the rack. If the enclosure
is being loaded into the rack above chest level, a third person must assist with aligning the
enclosure with the rails while the other two people support the weight of the enclosure.

Hard drive overview
The MDS600 supports up to 35 SAS or SATA hard drives per storage drawer. Always populate hard
drive bays from the rear to the front starting with the highest device bay ID number ("Device bay ID
numbers" on page 10). All unpopulated drive bays require drive blanks to properly distribute air flow and
cool the installed drives.
SAS and SATA hard drive guidelines
When adding hard drives to the hard drive drawer, observe the following general guidelines:
•Verify that the drives are fully seated before closing the drawer.
•The drawer is fully closed when the fans slow down to their normal speed.
•The drawer should be closed with the handle in the released position.
•Hard drives are sensitive to excess vibration. Use care when opening and closing the drawer.
•A RAID 1 mirror requires an even number of hard drives.
•Drives that will be configured within an array should be the same capacity to provide the greatest
storage space efficiency.
NOTE: ACU does not support mixing SAS and SATA drives in the same logical volume.
Installing the hard drives
1. Be sure all I/O bays contain either an I/O module or an I/O blank. The hard drive drawer does not
open if I/O bays are empty.
