ES4710BD 10 Slots L2/L3/L4 Chassis Switch
2.1.7 Power Supply Requirements
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
DC: -36 ~ -72 VDC
Total power consumption:
≤
700W
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 system should include in a fuse or
circuit-breaker of no greater than 240V, 10A. It is recommended to use a UPS for more reliable
power supply.
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.
2.2 Preparing for Installation
After verifying site requirements, please check the contents of the switch container and accessory kit.
(If you are concerned that any item is missing or an incorrect item has been supplied, please contact
your dealer as soon as possible.)
2.2.1 Checking Switch Hardware Configuration and
