  CAUTION:  If a third-party rack is used, observe the following additional requirements to ensure adequate 
airflow and to prevent damage to the equipment: 
•  Front and rear doors—If the 42U rack includes closing front and rear doors, you must allow 5,350 sq 
cm (830 sq in) of holes evenly distributed from top to bottom to permit adequate airflow (equivalent to 
the required 64 percent open area for ventilation). 
•  Side—The clearance between the installed rack component and the side panels of the rack must be a 
minimum of 7 cm (2.75 in). 
 
Temperature requirements 
To ensure continued safe and reliable equipment operation, install or position the system in a well-
ventilated, climate-controlled environment. 
The maximum recommended ambient operating temperature (TMRA) for most server products is 35°C 
(95°F). The temperature in the room where the rack is located must not exceed 35°C (95°F). 
  CAUTION:  To reduce the risk of damage to the equipment when installing third-party options: 
•  Do not permit optional equipment to impede airflow around the server or to increase the internal rack 
temperature beyond the maximum allowable limits. 
•  Do not exceed the manufacturer’s TMRA. 
 
Power requirements 
Installation of this equipment must comply with local and regional electrical regulations governing the 
installation of information technology equipment by licensed electricians. This equipment is designed to 
operate in installations covered by NFPA 70, 1999 Edition (National Electric Code) and NFPA-75, 1992 
(code for Protection of Electronic Computer/Data Processing Equipment). For electrical power ratings on 
options, refer to the product rating label or the user documentation supplied with that option. 
  WARNING:  To reduce the risk of personal injury, fire, or damage to the equipment, do 
not overload the AC supply branch circuit that provides power to the rack. Consult the 
electrical authority having jurisdiction over wiring and installation requirements of your 
facility.
 
  CAUTION:  Protect the server from power fluctuations and temporary interruptions with a regulating 
uninterruptible power supply (UPS). This device protects the hardware from damage caused by power 
surges and voltage spikes and keeps the system in operation during a power failure. 
When installing more than one server, you may need to use additional power distribution devices to 
safely provide power to all devices. Observe the following guidelines: 
 
Balance the server power load between available AC supply branch circuits. 
 
Do not allow the overall system AC current load to exceed 80 percent of the branch circuit AC 
current rating. 
 
Do not use common power outlet strips for this equipment. 
 
Provide a separate electrical circuit for the server. 
 
Electrical grounding requirements 
The server must be grounded properly for proper operation and safety. In the United States, you must 
install the equipment in accordance with NFPA 70, 1999 Edition (National Electric Code), Article 250, 
as well as any local and regional building codes. In Canada, you must install the equipment in 
accordance with Canadian Standards Association, CSA C22.1, Canadian Electrical Code. In all other 
countries, you must install the equipment in accordance with any regional or national electrical wiring 
codes, such as the International Electrotechnical Commission (IEC) Code 364, parts 1 through 7.
