Similar to other electronic products, the semiconductor chip easily gets damaged if you power
on or off abruptly and frequently. To restart up the switch of ASCENT AS3424S, you have to
open the power on-off after the power is cut down for three to five seconds.
Avoid severe collision or falling down from the height to protect the parts in the switch.
Use correct outside ports to connect the switch of ASCENT AS3424S. Do not put the Ethernet
plug into the console port (RJ45 8-line socket). Similarly, do not put the console cable into the
console port (RJ45 8-line socket).
Note
1. When you plug or dial the power line, keep the power line horizontal with the power socket.
2. When the lifetime of our products ends, handle them according to national laws and
regulations, or send these products to our company for collective processing.
 Keep dustless and clean during or after the installation.
 Put the cover at the safe place.
 Put tools at the right place where they are not easily falling down.
 Put on relatively tight clothes, fasten the tie or scarf well and roll up the sleeve, avoiding
stumbling the machine box.
 Put on the protective glasses if the environment may cause damage to your eyes.
 Avoid incorrect operations that may cause damage to human or devices.
The safety notices mentioned here means that improper operation may lead to body damage.
 Read the installation guide carefully before you operate the system.
 Only professionals are allowed to install or replace the switch.
 Pull out the AC power socket and close the direct-current power before operating on the
machine box or working beside the power source.
 The final configuration of products must comply with relative national laws and regulations.
When you work under electricity, following the following principles:

 Put off ornaments, such as ring, necklace, watch and bracelet, before you operate under live
working. When metal articles connect the power to the ground, short circuit happens and
components may be damaged.
 Pull out the AC power socket and close the direct-current power before operating on the
machine box or working beside the power source.
 When the power is on, do not touch the power.
 Correctly connect the device and the power socket.
 Only professionals are allowed to operate and maintain the device.
 Read the installation guide carefully before the system is powered on.
Notes:
1. Check potential dangers, such as the humid floor, ungrounded extensible power line and tatty
power line.
2. Install the emergent on-off at the working room for turning off the power when trouble happens.
3. Turn off the power on-off of the switch and plug off the power line before installing or uninstalling
the machine box or working beside the power.
4. Do not work alone if potential dangers exist.
5. Cut off the power before checkout.
6. If trouble happens, take the following measures:
Cut off the system's power.
Alarm.
Take proper measures to help persons who are hit by the disaster. Artificial respiration is
needed if necessary.
Seek for medical help, or judge the loss and seek for available help.
Electrostatic discharge may damage devices and circuits. Improper treatment may cause the
switch to malfunction completely or discontinuously.
Move or locate the devices according to the measures of electrostatic discharge prevention,
ensuring the machine box connects the ground. Another measure is to wear the static-proof
hand ring. If there is no hand ring, use the metal clip with the metal cable to clip the
unpainted metal part of the machine box. In this case, the static is discharged to the ground
through the metal cable of the clip. You can also discharge the static to the ground through
your body.
This part describes the requirements for the installation locations.

The switch can be installed on the desk or the cabinet. The location of the machine box,
cabinet planning and indoor cabling are very important for normal system’s function. Short
distance between devices, bad ventilation and untouchable control plate will cause
maintenance problems, systematic faulty and breakdown.
For location planning and device locating, refer to section 2.3.2 “Location Configuration
Prevention”.
The following preventive measures assist you to design the proper environment for the
switch.
 Make sure that the workshop is well-ventilated, the heat of electrical devices is well-discharged
and sufficient air circulation is provided for device cooling.
 Avoid to damage devices by following the electrostatic discharge prevention procedure.
 Put the machine box at the place where cool air can blow off the heat inside the machine box.
Make sure the machine box is sealed because the opened machine box will reverse the cool air
flow.
The following content assists you to make a proper cabinet configuration:
 Each device on the cabinet gives off heat when it runs. Therefore, the sealed cabinet must have
the heat-discharge outlet and the cooling fan. Do not put the devices too close, avoiding bad
ventilation.
 When you install the machine box at the open cabinet, prevent the frame of the cabinet from
blocking the airway of the machine box.
 Ensure that nice ventilation is provided for the devices installed at the bottom of the cabinet.
 The clapboard separates exhaust gas and inflow air, and boost cool air to flow in the machine
box. The best location of the clapboard is decided by the air flow mode in the machine box,
which can be obtained through different location tests.
Make sure that the power supply has nice grounding and the power at the input side of the
switch is reliable. The voltage control can be installed if necessary. At least a 240 V, 10A fuse
or a breaker is provided in the phase line if you prepare the short-circuit prevention measures
for a building.
Warning
If the power supply system does not have good grounding, or the input power disturbs too much
and excessive pulses exist, the error code rate of communication devices increases and even the
hardware system will be damaged.
