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!
2.1.1.4 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
Precautions should be taken to prevent power source interruptions
Provide the system with a dedicated grounding, rather than sharing the grounding with the
electronic equipment or lightning protection devices
Keep away from high power radio transmitters, radar transmitters, and high frequency strong
circuit devices
Provide electromagnetic shielding if necessary
2.1.1.6 Rack Configuration
The dimensions of the switch designed to be mounted on a standard 19’’ rack, Please ensure good
ventilation for the rack
Every device in the rack will generate heat during operation, therefore vent and fans must be
provided for an enclosed rack, and devices should not be stacked closely.
When mounting devices in an open rack, care should be taken to prevent the rack frame from
obstructing the switch ventilation openings. Be sure to check the positioning of the switch after
installation to avoid the aforementioned.
Caution !!
If a standard 19’’ rack is not available, the switch can be placed on a clean level desktop, leave a
clearance of 10mm around the switch for ventilation, and do not place anything on top of the switch
2.1.2 Installation Notice
Read through the installation instruction carefully before operating on the system. Make sure the
