Environmental Requirements
This section provides the environmental, power dissipation, noise emission, and air flow specifications.
Temperature and Humidity Specifications
NOTE The values in Table 2-14 meet or exceed all ASHRAE specifications.
Power Dissipation
Table 2-15 lists the power requirements by configuration (number of cell boards, amount of memory per cell,
and number of I/O chassis) for the HP Integrity Superdome/sx2000.
The table contains two columns of power numbers expressed in watts. The Breaker Power column lists the
power used to size the wall breaker at the installation site. The Typical Power column lists typical power.
Typical power numbers can be used to assess the average utility cost of cooling and electrical power.
Table 2-15 also lists the recommended breaker sizes for 4-wire and 5-wire sources.
