Environmental

Maximum vibration

Operating 0.26 G

rms

at 5 Hz to 350 Hz (all operation orientations).

Storage 1.87 G

rms

at 10 Hz to 500 Hz for 15 min (all six sides

tested).

Maximum shock

Operating One shock pulse in the positive z axis of 31 G for 2.6 ms in

all operational orientations.

Storage Six consecutively executed shock pulses in the positive

and negative x, y, and z axes (one pulse on each side of

the system) of 71 G for up to 2 ms.

Maximum altitude

Operating

3,0482000 m (10,0006560 ft)

Storage 12,000 m (39,370 ft).

Operating altitude de-rating

Up to 35°C (95°F) Maximum temperature is reduced by 1°C/300 m (1°F/547

ft) above 950 m (3,117 ft).

35 °C–40°C (95 °F–104°F) Maximum temperature is reduced by 1°C/175 m (1°F/319

ft) above 950 m (3,117 ft).

40 °C–45°C (104 °F–113°F) Maximum temperature is reduced by 1°C/125 m (1°F/228

ft) above 950 m (3,117 ft).

Particulate contamination

NOTE: This section defines the limits to help avoid IT equipment damage and/or failure from particulates and gaseous

contamination. If it is determined that levels of particulates or gaseous pollution are beyond the limits specified below and

are the reason for the damage and/or failures to your equipment, it may be necessary for you to re-mediate the

environmental conditions that are causing the damage and/or failures. Re-mediation of environmental conditions will be the

responsibility of the customer.

Air filtration

NOTE: Applies to data center environments only. Air

filtration requirements do not apply to IT equipment

designed to be used outside a data center, in

environments such as an office or factory floor.

Data center air filtration as defined by ISO Class 8 per ISO

14644-1 with a 95 percent upper confidence limit.

NOTE: Air entering the data center must have

MERV11 or MERV13 filtration.

Conductive dust

NOTE: Applies to data center and non-data center

environments.

Air must be free from conductive dust, zinc whiskers, or

other conductive particles.

Corrosive dust

NOTE: Applies to data center and non-data center

environments.

● Air must be free of corrosive dust.

● Residual dust present in the air must have a

deliquescent point less than 60% relative humidity.

Gaseous contamination

NOTE: Maximum corrosive contaminant levels measured at ≤50% relative humidity.

Copper coupon corrosion rate <300 Å/month per Class G1 as defined by ANSI/

ISA71.04-1985.

Silver coupon corrosion rate <200 Å/month as defined by AHSRAE TC9.9.
