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 contin-
ued 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 re-
covered within 5 hours.
2.1.3.Power Supply
Before powering on the power supply, please check the power input to ensure prop-
er grounding of the power supply system. The input source for the switch should be relia-
ble and secure; a voltage adaptor can be used if necessary. The building’s circuit protec-
tion system should include in the circuit a fuse or circuit-breaker of no greater than 240 V,
5A. It is recommended to use a UPS for more reliable power supplying. .
Caution!
1. Improper power supply system grounding, extreme fluctuation of the input source,
and transients (or spikes) can result in larger error rate, or even hardware damage!
2. Disconnect power supply cords before servicing!
2.1.4.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.
2.1.5.Anti-interference
All sources of interference, whether from the device/system itself or the outside envi-
ronment, will affect operations in various ways, such as capacitive coupling, inductive
coupling, electromagnetic radiation, common impedance (including the grounding sys-
tem) and cables/lines (power cables, signal lines, and output lines). The following should
be noted:
■
Precautions should be taken to prevent power source interruptions;
■
Provide the system with a dedicated grounding, rather than sharing the grounding
