The SR550 server has the following dimensions and weight (approximate):

• Height: 87 mm (3.4 in.)
• Width: 445 mm (17.5 in.)
• Depth: 720 mm (28.3 in.)
• Weight:
  • Minimum configuration: 19 kg (41.9 lb)
  • Maximum configuration: 26 kg (57.3 lb)

The SR550 server complies with ASHRAE class A2 specifications. The server performance might be impacted when the operating temperature is outside the ASHRAE A2 specifications. Some server models comply with ASHRAE class A3 and class A4 specifications, provided they meet the following hardware configuration requirements at the same time:

• Two power supplies installed
• No system fan failure

The SR550 server is supported in the following environment:

• Air temperature:
  • Operating:
    • ASHRAE Class A4: 5 °C - 45 °C (41 °F - 113 °F); for altitudes above 900 m (2,953 ft), decrease the maximum ambient temperature by 1 °C for every 125-m (410-ft) increase in altitude
    • ASHRAE Class A3: 5 °C - 40 °C (41 °F - 104 °F); for altitudes above 900 m (2,953 ft), decrease the maximum ambient temperature by 1 °C for every 175-m (574-ft) increase in altitude
    • ASHRAE Class A2: 10 °C - 35 °C (50 °F - 95 °F); for altitudes above 900 m (2,953 ft), decrease the maximum ambient temperature by 1 °C for every 300-m (984-ft) increase in altitude
  • Non-operating: 5 °C - 45 °C (41 °F - 113 °F)
  • Storage: -40 °C - +60 °C (-40 °F - 140 °F)
• Maximum altitude: 3,050 m (10,000 ft)
• Humidity:
  • Operating:
    • ASHRAE Class A4: 8% - 90% (non-condensing); maximum dew point: 24 °C (75 °F)
    • ASHRAE Class A3: 8% - 85% (non-condensing); maximum dew point: 24 °C (75 °F)
    • ASHRAE Class A2: 8% - 80% (non-condensing); maximum dew point: 21 °C (70 °F)
  • Storage: 8% - 90% (non-condensing)
