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:
- 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)
- 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)
Power requirements for each power supply
To aid in power and cooling requirements planning, Table 1 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.
| 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.

Notes:
Important: Government regulations (such as
those prescribed by OSHA or European Community Directives) may govern
noise level exposure in the workplace and may apply to you and your
server installation. This system is available with an optional acoustical
door feature that can help reduce the noise emitted from this system.
The actual sound pressure levels in your installation depend upon
a variety of factors, including the number of racks in the installation;
the size, materials, and configuration of the room where you designate
the racks to be installed; the noise levels from other equipment;
the room ambient temperature, and employees' location in relation
to the equipment. Further, compliance with such government regulations
also depends upon a variety of additional factors, including the duration
of employees' exposure and whether employees wear hearing protection.
IBM recommends that you consult with qualified experts in this field
to determine whether you are in compliance with the applicable regulations.
