Environmental Requirements And Specifications For Ex4100 And Ex4100-F Switches - Juniper EX4100 Hardware Manual

Environmental Requirements and Specifications for EX4100 and EX4100-
F Switches
You must install the switch in a rack or cabinet. You must house it in a dry, clean, well-ventilated, and
temperature-controlled environment.
Follow these environmental guidelines:
• Ensure that the site is as dust-free as possible. Dust can clog air intake vents and filters, reducing the
efficiency of the switch cooling system.
• Maintain ambient airflow for normal switch operation. If the airflow is blocked or restricted, or if the
intake air is too warm, the switch might overheat. If the switch overheats, the switch temperature
monitor may shut down the device to protect the hardware components.
The following are the required environmental conditions for normal switch operation of EX4100 and
EX4100-F switches.
• Switch: All EX4100 and EX4100-F switch models
• Altitude: No performance degradation up to 5,000 feet (1, 524 meters)
• Relative humidity: Normal operation ensured in relative humidity range of 10% through 85%,
noncondensing
• Temperature:
• Normal operation ensured in temperature range of 32 °F through 113 °F (0 °C through 45 °C)
• Nonoperating storage temperature in shipping container: –40 °F through 158 °F (–40 °C through
70 °C)
• Seismic tolerance: Tested for Zone 4 earthquake safety.
NOTE: With 10G-Base-T pluggable, max temperature is reduced to 40C up to 5,000ft elevation.
NOTE: Install the EX4100 and EX4100-F switch only in restricted areas, such as dedicated
equipment rooms and equipment closets. Install the switch in accordance with Articles of the
National Electrical Code, ANSI/NFPA 70.
