1Values in Table 2-15are based on 25 W load I/O cards, 1 GB DIMMs and four Intel® Itanium ® single-core processors

with 9 MB cache per cell board.

2These numbers are valid only for the specific configurations shown. Any upgrades can require a change to the breaker size. A 5-wire source uses a 4-pole breaker, and a 4-wire source uses a 3-pole breaker. The protective earth (PE) ground wire is not switched.

Acoustic Noise Specification

The acoustic noise specifications are as follows:

•8.2 bel (sound power level)

•65.1 dBA (sound pressure level at operator position)

These levels are appropriate for dedicated computer room environments, not office environments.

You must understand the acoustic noise specifications relative to operator positions within the computer room when adding HP Integrity Superdome/sx2000 systems to computer rooms with existing noise sources.

Airflow

HP Integrity Superdome/sx2000 systems require the cabinet air intake temperature to be between 15οC and 32οC (59οF and 89.6οF) at 2900 CFM.

Figure 2-2illustrates the location of the inlet and outlet air ducts on a single cabinet.
