Environmental requirements

Before you install a system, your physical environment must meet certain requirements. This includes verifying that adequate space is available and that requirements for power and environmental conditions are met.

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 equipment–personal 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. (R001 part 1 of 2)
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. (R001 part 2 of 2)
Important: In addition, remember the following guidelines:
  • The rack design must support the total weight of the installed enclosures. Incorporate stabilizing features suitable to prevent the rack from tipping or being pushed over during installation or normal use.
  • The rack design must consider the maximum enclosure operating ambient temperature of 35-degrees C (95-degrees Fahrenheit).
  • 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. Observer the electrical power consumption rating that is shown on the nameplate.
  • The electrical distribution system must provide a reliable ground for each enclosure in the rack.

Power requirements for each power supply

To aid in power and cooling requirements planning, Power specifications per power supply lists the rating of each power supply unit (PSU) by enclosure. Each enclosure contains two AC PSUs for redundancy. The power rating values represent the total power drawn by both PSUs. The power that is used by the system depends on various factors, including the number of enclosures and drives in the system and the ambient temperature.

Table 1. Power specifications per power supply
Model and type PSU Input power requirements Maximum input current Maximum power output Caloric value (BTU/hr)
Lenovo Storage V series AC 800 W Single phase AC: 100 V to 127 V or 200 V to 240 V

Frequency: 50-60 Hz

100 V to 127 V 9 A

200 V to 240 V 4.5 A

800 W 2730

The measurements that are shown in the following tables were obtained in the specific operating environment and under the conditions described. These measurements are presented as an illustration; measurements that are obtained in other operating environments might vary. Conduct your own testing to determine specific measurements for your environment.

Temperature requirements

Ensure that the temperature and humidity in the environment falls within the ranges shown in Temperature requirements. System airflow is from the front to the rear of each enclosure:
  • Airflow passes between drive carriers and through each enclosure.
  • Airflow for the upper 4U of the 5U enclosure enters the front, passes between the disk drives, and exits through the large fans in the rear of the enclosure.
  • Airflow for the lower 1U of the 5U enclosure is driven through the power supplies via 40mm X 56mm fans. Air continues through the chassis cooling the ESMs or controllers and exits the rear of the enclosure.
  • The combined power and cooling module exhausts air from the rear of each canister.
