Environmental specifications

The PowerEdge XR11 system operates in these environmental categories: ASHRAE A2/A3/A4 and Rugged.

NOTE:For additional information about environmental certifications, see the Product Environmental Datasheet that is located with the Documentation > Regulatory Information on www.dell.com/support/home.

Table 1. Continuous operation specifications for ASHRAE A2 This table describes the operational climatic range for category A2.
	Allowable continuous operations
Temperature range for altitudes <= 900 m (<= 2953 ft)	10–35°C (50–95°F) with no direct sunlight on the equipment
Humidity percent range (non-condensing at all times)	8% RH with -12°C minimum dew point to 80% RH with 21°C (69.8°F) maximum dew point
Operational altitude de-rating	Maximum temperature is reduced by 1°C/300 m (1.8°F/984 Ft) above 900 m (2953 Ft).

Table 2. Continuous operation specifications for ASHRAE A3 This table describes the operational climatic range for category A3.
	Allowable continuous operations
Temperature range for altitudes <= 900 m (<= 2953 ft)	5–40°C (41–104°F) with no direct sunlight on the equipment
Humidity percent range (non-condensing at all times)	8% RH with -12°C minimum dew point to 85% RH with 24°C (75.2°F) maximum dew point
Operational altitude de-rating	Maximum temperature is reduced by 1°C/175 m (1.8°F/574 Ft) above 900 m (2953 Ft).

Table 3. Continuous operation specifications for ASHRAE A4 This table describes the operational climatic range for category A4.
	Allowable continuous operations
Temperature range for altitudes <= 900 m (<= 2953 ft)	5–45°C (41–113°F) with no direct sunlight on the equipment
Humidity percent range (non-condensing at all times)	8% RH with -12°C minimum dew point to 90% RH with 24°C (75.2°F) maximum dew point

Table 4. Continuous operation specifications for Rugged This table describes the operational climatic range for category A4.
	Allowable continuous operations
Temperature range for altitudes <= 900 m (<= 2953 ft)	(-5)–55°C (23–131°F) with no direct sunlight on the equipment
Humidity percent range (non-condensing at all times)	8% RH with -12°C minimum dew point to 90% RH with 24°C (75.2°F) maximum dew point
Operational altitude de-rating	Maximum temperature is reduced by 1°C/80 m (1.8°F/410 Ft) above 900 m (2953 Ft).

Table 5. Common environmental specifications for ASHRAE A2, A3, A4, and Rugged This table describes the shared requirements across all categories.
	Allowable continuous operations
Maximum temperature gradient (applies to both operation and non-operation).	20°C in an hour* (36°F in an hour) and 5°C in 15 minutes (41°F in 15 minutes), 5°C in an hour* (41°F in an hour) for tape NOTE:* - Per ASHRAE thermal guidelines for tape hardware, these are not instantaneous rates of temperature change.
