2.1.4 Preventing Electrostatic Discharge Damage
Static electric discharges can cause damage to internal circuits, even the entire switch. Follow these
guidelines for preventing ESD damage:
1.
Ensure proper earth grounding of the device
2.
Perform regular cleaning to reduce dust
3.
Maintain proper temperature and humidity
4.
Always wear an ESD wrist strap and antistatic uniform when in contact with circuit boards
2.1.5 Anti-interference Requirements
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:
1.
Precautions should be taken to prevent power source interruptions
2.
Provide the system with a dedicated grounding, rather than sharing the grounding with
electronic equipment or lightning protection devices
3.
Keep away from high power radio transmitters, radar transmitters, and high frequency strong
circuit devices
4.
Provide electromagnetic shielding if necessary
2.1.6 Rack Configuration
The dimensions of the ES4710BD are designed to be mounted on a standard 19'' rack, the
dimensions are 436mm x 797mm x 478mm (W x H x D). 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.
Notice
If a standard 19'' rack is not available, the ES4710BD can be placed on a clean level desktop, leave
a clearance of 100mm around the switch for ventilation, and do not place anything on top of the
switch.
