Specification Description
Power supplies
• This server supports three types of hot-swap power supply units:
– 1100-watt power supply
– input voltage 110V, 220V, or 240V ac
– 1600-watt power supply
– input voltage 220V or 240V ac
– 2000-watt power supply
– input voltage 220V ac
• The power subsystem supports balanced N+N redundancy operation, where N =
1 or 2.
CAUTION:
1. 240 V dc input (input range: 180-300 V dc) is ONLY supported in Chinese
Mainland.
2. Power supplies with 240 V dc are not hot-swappable. To remove the power
cord, ensure you have turned off the server or disconnected the dc power
sources at the breaker panel.
3. In order for the ThinkSystem products to operate error free in both a DC or
AC electrical environment, a TN-S earthing system which complies to
60364-1 IEC 2005 standard has to be present or installed.
Minimal configuration for
debugging
• Two processors in processor sockets 1 and 2
• Two DRAM DIMMs in slot 8 and 20
• One power supply in slot 1
• One drive with HBA adapter and backplane
• Six system fans (fans 1 to 6)
Acoustical noise emissions
(base configuration)
• Sound power, idling: 6.1 bels
• Sound power, operating: 6.1 bels
Note:
The options supported in this server vary in function, power consumption, and
required cooling. Any increase in cooling required by these options will increase the
fan speed and generated sound level. The actual sound pressure levels measured 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; the noise levels of
other equipment; the room ambient temperature and barometric pressure; and the
location of employees in relation to the equipment.
