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

Static electric discharges can cause damage to internal circuits, even the entire

switch. Follow these guidelines for avoiding ESD damage:

Ensure proper earth grounding of the device;



Perform regular cleaning to reduce dust;



Maintain proper temperature and humidity;



Always wear an ESD wrist strap and antistatic uniform when in contact with circuit



boards.

2.1.1.5 Anti-interference

All sources of interference, whether from the device/system itself or the outside

environment, will affect operations in various ways, such as capacitive coupling, inductive

coupling, electromagnetic radiation, common impedance (including the grounding system)

and cables/lines (power cables, signal lines, and output lines). The following should be

noted:
