Humidity Requirements
Humidity Requirements
High humidity can cause moisture to enter the switch. Moisture can cause corrosion of internal components
and degradation of properties such as electrical resistance, thermal conductivity, physical strength, and size.
The switch is rated to withstand from 5- to 95-percent (nonoperating) and 5- to 90-percent (operating) relative
humidity.
Climate-controlled buldings usually maintain an acceptable level of humidity for the switch equipment. If the
switch is located in an unusually humid location, use a dehumidifier to maintain the humidity within an
acceptable range.
This switch operateas at 5- to 90-percent non-condensing relative humidity.
Altitude Requirements
Altitude rating is 10,000 ft (3048 m). For China, it is 6,562 ft (2000 m).
Altitude rating is 0-10,000 ft (3048 m). For every 1000 feet (300 meters) of elevation, the maximum ambient
temperature is reduced by one degree Celsius.
Dust and Particulate Requirements
Exhaust fans cool power supplies. System fans cool switches by drawing in air and exhausting air out through
various openings in the chassis. Fans also introduce dust and other particles, causing contaminant buildup in
the switch and increased internal chassis temperature. Dust and particles can act as insulators and interfere
with the mechanical components in the switch. Keep a clean operating environment to reduce the negative
effects of dust and other particles.
In addition to keeping your environment free of dust and particles, use these precautions to avoid contamination
of your switch:
• Do not smoke near the switch.
• Do not eat or drink near the switch.

• System sends SNMP notifications (if configured).
For sensor 2 (intake sensor):
• If the threshold is exceeded in a switching module, only that module is shut down.
• If the threshold is exceeded in an active supervisor module with HA-standby or standby present,
only that supervisor module is shut down and the standby supervisor module takes over.
• If you do not have a standby supervisor module in your switch, you have 2 minutes to decrease the
temperature. During this interval, the software monitors the temperature every 5 seconds and
continuously sends system messages, as configured.
