Notes:
  1. The power supplies automatically accept any voltage with the published, rated-voltage range. If dual power supplies are installed and operating, the power supplies draw approximately equal current from the utility (electrical supply) and provide approximately equal current to the load.
  2. Power draw and heat load vary greatly by configuration. When you plan for an electrical system, it is important to use the maximum values. However, when you plan for heat load, you can use the IBM® Systems Energy Estimator to obtain a heat output estimate based on a specific configuration. For more information, see The IBM Systems Energy Estimator website.
  3. To calculate the amperage, multiply the kVA by 1000 and divide that number by the operating voltage.
  4. AC and HVDC power supplies cannot be mixed in the same server or I/O drawer. IBM recommends that AC products and HVDC products with HVDC PDUs are installed in separate racks. However, AC and HVDC products can be supported in the same rack if all grounding (earthing) is done in accordance with the applicable electrical code or codes. IBM provides documentation for different AC and HVDC products about the disconnecting means for service. If a different disconnecting means is to be used for service of the equipment in a rack with AC-powered and DC-powered products, the disconnecting means must be made clear to service.
  5. When either the 8247-22L or 8284-22A is operating on only one power supply, over subscription is not available. In this situation, the maximum values are 1520 W, 1.6 kVA, and 5188 BTU/hr

Notes:
  1. The power supplies automatically accept any voltage with the published, rated-voltage range. If multiple power supplies are installed and operating, the power supplies draw approximately equal current from the utility (electrical supply) and provide approximately equal current to the load.
  2. Power draw and heat load vary greatly by configuration. When you plan for an electrical system, it is important to use the maximum values. However, when you plan for heat load, you can use the IBM Systems Energy Estimator to obtain a heat output estimate based on a specific configuration. For more information, see The IBM Systems Energy Estimator website.
  3. To calculate the amperage, multiply the kVA by 1000 and divide that number by the operating voltage.
  4. Model 8286-41A in a tower version includes two 900-watt PSUs. Model 8286-41A in a rack-mounted version includes two 1400-watt PSUs, but is also available with two 900-watt PSUs through RPQ number 8A2217.
  5. AC and HVDC power supplies cannot be mixed in the same server or I/O drawer. IBM recommends that AC products and HVDC products with HVDC PDUs are installed in separate racks. However, AC and HVDC products can be supported in the same rack if all grounding (earthing) is done in accordance with the applicable electrical code or codes. IBM provides documentation for different AC and HVDC products about the disconnecting means for service. If a different disconnecting means is to be used for service of the equipment in a rack with AC-powered and DC-powered products, the disconnecting means must be made clear to service.
  6. When the system is operating on only two power supplies, over subscription is not available. In this situation, the maximum values are 1790 W, 1.85 kVA, and 6110 BTU/hr.

Notes:
  1. IBM provides the recommended operating environment as the long-term operating environment that can result in the greatest reliability, energy efficiency, and reliability. The allowable operating environment represents where the equipment is tested to verify functionality. Due to the stresses that operating in the allowable envelope can place on the equipment, these envelopes must be used for short-term operation, not continuous operation.
  2. Must derate the maximum allowable temperature 1°C (1.8°F) per 175 m (574 ft) above 900 m (2953 ft) up to a maximum allowable elevation of 3050 m (10000 ft).
  3. The minimum humidity level is the larger absolute humidity of the -12°C (10.4°F) dew point and the 8% relative humidity. These levels intersect at approximately 25°C (77°F). Below this intersection, the dew point (-12°C) represents the minimum moisture level, while above it, the relative humidity (8%) is the minimum. For the upper moisture limit, the limit is the minimum absolute humidity of the dew point and relative humidity that is stated.
  4. The following minimum requirements apply to data centers that are operated at low relative humidity:
    • Data centers that have do not have ESD floors and where people are allowed to wear non-ESD shoes might want to consider increasing humidity given that the risk of generating 8 kV increases slightly at 8% relative humidity, when compared to 25% relative humidity.
    • All mobile furnishings and equipment must be made of conductive or static dissipative materials and be bonded to ground.
    • During maintenance on any hardware, a properly functioning and grounded wrist strap must be used by any personnel who comes in contact with information technology (IT) equipment.
  5. Equipment that is removed from the original shipping container and is installed, but is powered down. The allowable non-operating environment is provided to define the environmental range that an unpowered system can experience short term without being damaged.

  5. Notice: Government regulations (such as those prescribed by OSHA or European Community Directives) might govern noise level exposure in the workplace and might apply to you and your server installation. This IBM system is available in racks FC 7014-T00 and 7014-T42 with an optional acoustical door feature that can help reduce the noise that is emitted from this system. The actual sound pressure levels in your installation depend upon various 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 various extra 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.
  6. IBM recommends limiting a rack to ten 8247-21L servers or alternatively use racks FC 7014-T00 or 7014-T42 with acoustical doors (FC 6248 or 6249) installed to limit the acoustical noise.

Notes:
  1. Declared level LWad is the upper-limit A-weighted sound power level. Declared level LpAm is the mean A-weighted emission sound pressure level that is measured at the 1-meter bystander positions.
  2. All measurements made in conformance with ISO 7779 and declared in conformance with ISO 9296.
  3. 10 dB (decibel) equals 1 B (bel).
  4. Estimated.
  5. Notice: Government regulations (such as those prescribed by OSHA or European Community Directives) might govern noise level exposure in the workplace and might apply to you and your server installation. This IBM system is available in racks FC 7014-T00 and 7014-T42 with an optional acoustical door feature that can help reduce the noise that is emitted from this system. The actual sound pressure levels in your installation depend upon various 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 various extra 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.

Special Hardware Management Console considerations

When the server is managed by a Hardware Management Console (HMC), the console must be provided within the same room and within 8 m (26 ft) of the server. For additional considerations, see Installing and configuring the HMC.

Note: As an alternative to the local HMC requirement, you can provide a supported device, such as a PC, with connectivity and authority to operate through a remotely attached HMC. This local device must be in the same room and within 8 m (26 ft) of your server. This local device must provide functional capabilities that are equivalent to the HMC that it replaces. This local device is needed by the service representative to service the system.
