Notes:
1. Noise levels cited are for a typical configuration (Bulk Power, CEC cage, battery option, media drawer, and two
I/O drawers).
2. The 0.6-B (6-dB) reduction in noise emission levels with the acoustical rear door corresponds to a factor of 4
reduction. That is, the noise level of a single frame with thin covers is about the same as the noise level of four
frames with acoustical covers.
3. L
WAd
is the upper-limit A-weighted sound power level; LpAm is the mean A-weighted sound pressure level at the
1-meter bystander positions; 1 B = 10 dB.
4. All measurements made in conformance with ISO 7779 and declared in conformance with ISO 9296.

Notes:
1. When an IBM-approved vapor bag and desiccant packets are used to protect the system, storage specifications
are valid for 6 months and shipping specifications are valid for 1 month. Otherwise, storage and shipping
specifications are valid for two weeks each.
2. The upper limit of the dry bulb temperature must be derated 1 degree C per 189 m (619 ft.) above 1295 m (4250
ft.). Maximum altitude is 3048 m (10,000 ft.).
