Caution!
A sample of ambient temperature and humidity should be taken at 1.5m above the
floor and 0.4m in front of the switch rack, with no protective panel covering the front and
rear of the rack. Short term working conditions refer to a maximum of 48 hours of
continued operation and an annual cumulative total of less than 15 days. Formidable
operation conditions refers to the ambient temperature and relative humidity value that
may occur during an air-conditioning system failure, and normal operation conditions
should be recovered within 5 hours.
2.1.1.3 Power Supply
Before powering on the power supply, please check the power input to ensure proper
grounding of the power supply system. The input source for the switch should be reliable
and secure; a voltage adaptor can be used if necessary. The building’s circuit protection
system should include in the circuit a fuse or circuit-breaker of no greater than 240 V, 10 A.
It is recommended to use a UPS for more reliable power supplying. .
Caution!
Improper power supply system grounding, extreme fluctuation of the input power, and
transients (or spikes) can result in larger error rate, or even hardware damage!
2.1.1.4 Preventing Electrostatic Discharge Damage
