Safety notices

Use the following general safety information for all rack-mounted devices:

DANGER

Observe the following precautions when working on or around your IT rack system:

Heavy equipmentpersonal injury or equipment damage might result if mishandled.
Always lower the leveling pads on the rack cabinet.
Always install stabilizer brackets on the rack cabinet.
To avoid hazardous conditions due to uneven mechanical loading, always install the heaviest devices in the bottom of the rack cabinet. Always install servers and optional devices starting from the bottom of the rack cabinet.
Rack-mounted devices are not to be used as shelves or work spaces. Do not place objects on top of rack-mounted devices.
Each rack cabinet might have more than one power cord. Be sure to disconnect all power cords in the rack cabinet when directed to disconnect power during servicing.
Connect all devices installed in a rack cabinet to power devices installed in the same rack cabinet. Do not plug a power cord from a device installed in one rack cabinet into a power device installed in a different rack cabinet.
An electrical outlet that is not correctly wired could place hazardous voltage on the metal parts of the system or the devices that attach to the system. It is the responsibility of the customer to ensure that the outlet is correctly wired and grounded to prevent an electrical shock.

CAUTION:

Do not install a unit in a rack where the internal rack ambient temperatures will exceed the manufacturer's recommended ambient temperature for all your rack-mounted devices.
Do not install a unit in a rack where the air flow is compromised. Ensure that air flow is not blocked or reduced on any side, front, or back of a unit used for air flow through the unit.
Consideration should be given to the connection of the equipment to the supply circuit so that overloading of the circuits does not compromise the supply wiring or overcurrent protection. To provide the correct power connection to a rack, refer to the rating labels located on the equipment in the rack to determine the total power requirement of the supply circuit.
(For sliding drawers) Do not pull out or install any drawer or feature if the rack stabilizer brackets are not attached to the rack. Do not pull out more than one drawer at a time. The rack might become unstable if you pull out more than one drawer at a time.
(For fixed drawers) This drawer is a fixed drawer and must not be moved for servicing unless specified by the manufacturer. Attempting to move the drawer partially or completely out of the rack might cause the rack to become unstable or cause the drawer to fall out of the rack.

Important: In addition, remember:

The rack design must support the total weight of the installed enclosures and incorporate stabilizing features suitable to prevent the rack from tipping or being pushed over during installation or normal use.
The rack design must take into consideration the maximum enclosure operating ambient temperature of 35 degrees C (95 degrees Fahrenheit).
The system must be operated with low pressure rear exhaust installation with back pressure created by rack doors and obstacles not to exceed 5 pascals (0.5 mm water gauge).
The rack must have a safe electrical distribution system. It must provide overcurrent protection for the enclosure and must not be overloaded by the total number of enclosures installed. The electrical power consumption rating shown on the nameplate should be observed.
The electrical distribution system must provide a reliable ground for each enclosure in the rack.

Power requirements for each power supply (two per enclosure)

Ensure that your environment meets the following power requirements.

To aid in power and cooling requirements planning, Table 1 lists the rating of each power supply unit (PSU) by enclosure.

The power used by the system depends on a variety of factors, including the number of enclosures and drives in the system and the ambient temperature.

Environmental requirements

System airflow is from the front to the rear of each enclosure:

Airflow passes between drive carriers and through each enclosure.
The combined power and cooling module exhausts air from the rear of the each canister.
Back pressure from rack doors and other obstacles cannot exceed 5 pascals (0.5mm Water gauge).

Ensure that your environment falls within the ranges shown in Table 3.
