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
