The building’s circuit protection system should include a fuse or circuit-
breaker of no greater than 240 V, 10 A in the circuit. It is recommended to
use a UPS for more reliable power supply.
Caution
Caution
Caution
Caution
If the power supply is not grounded well, extreme fluctuations in the input
power or huge
pulse
result in the abnormal running of the switch, or
even
hardware
damage!
Anti-Static
Electrostatic currents damage to internal circuits or even the entire switch.
To avoid damage:
�
Ensure proper earth grounding of the device
�
Perform regular cleaning to reduce dust
�
Maintain proper temperature and humidity
�
Wear an ESD wrist strap and antistatic uniform when in contact with
circuit boards.
Anti-Interference
All
sources
of
interference,
whether
from
the
device
or
outside
environment, affect operations in various ways such as capacitive coupling,
induc
tive
coupling,
electromagnetic
radiation,
common
impedance
(
including
the
grounding
system) and cables/lines (power cables, signal
lines, and output lines).
Note

Note
Note
:
�
Prevent power interruptions
�
Provide the system with a dedicated grounding, rather than sharing
the grounding with electronic equipment or lightning protection
devices
�
Keep away from high power radio transmitters, radar transmitters,
and high frequency strong circuit devices
�
Provide electromagnetic shielding
Rack Configuration
The dimension of the switch is designed to be mounted on a standard 19’’
cabinet. To ensure good ventilation, pay attention as follows:
