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 ES4704BD are designed to be mounted on a standard 6’’ rack,
the dimensions are 440mm x 266mm x 421mm (W x H x D). 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.
¾ 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,.
¾ 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.
If a standard 19’’ rack is not available, the ES4700BD 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.
2.1.7 Power Supply Requirements
The ES4704BD is designed to use modular switching power supplies, supporting 1
+1 redundant backup of power modules. The power input specification is shown below:
Nominal Input Voltage
AC: 90 ~ 264 VAC, 50 ~ 60Hz
Total power consumption: ≤ 400W
The ES4710BD is designed to use modular switching power supplies, supporting 2
+1 redundant backup of power modules. The power input specification is shown below:
Nominal Input Voltage
AC: 90 ~ 264 VAC, 50 ~ 60Hz
Total power consumption: ≤ 1200W
Before installing the power modules, 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
