Room Requirements

To ensure that the installation site provides a properly equipped, cooled, and sized environment, make sure that the site:

  • Provides clearances for air circulation, opening cabinet doors, removing cabinet panels, and servicing the system from the front and rear.

    Locate the front and rear of the system at least 2.5 feet (ft) (0.76 meters (m)) away from walls and other obstructions.

  • Maintains reasonable temperature and humidity levels, and has a thermometer and humidistat to monitor room temperature and humidity.

    See AC Power and HVAC Service Requirements for detailed information about HVAC planning and System Specifications for detailed information about temperature and humidity requirements.

  • Is as free as possible of airborne contamination (particulate and gaseous).

    Notice: Due to the mission‐critical nature of Stratus servers, data centers housing the equipment should follow the guidelines of airborne contamination (particulate and gaseous) as outlined in the ASHRAE (TC) 9.9 documentation. Particulate matter to adhere to ISO 14644‐1 Class 8. Gaseous contamination, such as sulfur or chlorine‐bearing gases to adhere to ANSI/ISA‐71.04‐1985 Severity level G1.

    Dust buildup in the system can impede air circulation and heat transfer, causing components to become less reliable as the ambient temperature rises.

    Fans clogged by dust fail to expel hot air, causing circuit boards to overheat and fail.

    Dust on circuit boards raises the temperature, thus reducing the component's mean time between failure (MTBF).

    Dust circulating in the room increases the risk of fire within the room by providing potential combustible material within the environment.

    Dust contamination on tape devices causes mis‐reads and ‐writes, leading to failure of attempts to back up and restore data.

  • Provides two electrically separate grounded AC wall outlets, within reach of the power cords from the system or PDUs, and, if used, UPS units. If the power cord must be hardwired, consult an electrician to plan the length of the power cord.

  • Provides cutouts in the floor for routing cables, if the site has an elevated floor.

  • Contains space for future expansion.

    Caution: Do not place the system in an area of high electrostatic discharge. Static electricity may damage components. Do not locate components near transformers or other electromagnetic devices.
    Précaution: Ne pas placer le système dans une zone de forte décharge électrostatique. L’électricité statique peut endommager les composants. Ne pas placer de composants à proximité de transformateurs ou d’autres appareils électromagnétiques.

See System Specifications for the dimensions of system components.
