Any nonstandard and inaccurate electrical operation can cause accidents such as fires or electrical attacks, thus
causing severe, or even fatal damages to human bodies and the devices.
Direct or indirect touch through a wet object on high-voltage and mains supply can bring a fatal danger.
2.1.4 Electrostatic Discharge Damage Precautions
The M2-W6510-48V8C designing gives a great consideration to prevent electrostatic discharge damage and adopts
multiple measures. But if the electrostatic exceeds certain limit, it can still cause great damages to the circuitry and the
device. In networks connected by the M2-W6510-48V8C, the major sources of electrostatic induction are outdoor high
voltage transmission cables, lightening, indoor floor materials and the machine structure.
Pay attention to the following tips:
The device and the floor are well grounded.
Take dust prevention measures in the room.
Maintain an appropriate humidity.
When the pluggable modules of the switch are being installed, wear antistatic wrist strap and make sure the
antistatic wrist strap is well grounded.
Do not use bare hand to directly touch the components and the printed-circuit board (PCB) when the boards are
used.
Use an anti-static shielding bag to properly store the board.
Do not let any clothes touch a circuit board. An antistatic wrist strap can only prevent human static electricity from

accessories.
Be sure that the dimensions of the cabinet is appropriate for installation of the M2-W6510-48V8C that can reserve
a certain space for the front, back, left and right panels for heat dissipation.
The cabinet should be properly grounded.
2.2.2 Ventilation Requirements
For the M2-W6510-48V8C products, leave sufficient space in the front and at the back of the chassis (at least 20cm) for
ventilation. After various cables are connected, bundle the cables or place them in the cable management bracket to
avoid blocking air inlets. Dust the device every three months to avoid blocking the ventilation openings.
2.2.3 Temperature and Humidity Requirements
To ensure the normal operation and a prolonged service life of the M2-W6510-48V8C, maintain an appropriate
temperature and humidity in the equipment room. The equipment room with too high or too low temperature and
humidity for a long period of time may damage the equipment.
In an environment with high relative humidity, the insulating material may have bad insulation or even leak
electricity. And sometimes the materials may suffer from mechanical performance change and metallic parts may
get rusted.
On the other hand, in an environment with low relative humidity, the insulating strip may dry and shrink, and static
electricity may occur easily and endanger the circuit on the device.
In an environment with high temperature, the equipment is subjected to even greater harm, as its performance
may degrade significantly and its service life may be shortened at high temperature for long that expedites the
aging process.

2.2.6 EMI Consideration
Various interference sources, from either outside or inside the device or application system, affect the system in the
conductive ways such as capacitive coupling, inductive coupling, and electromagnetic radiation. There are two types of
electromagnetic interferences: radiated interference and conducted interference, depending on the type of the
propagation path. When the energy, often RF energy, from a component arrives at a sensitive component via the space,
the energy is known as radiated interference. The interference source can be either a part of the interfered system or a
completely electrically isolated unit. Conducted interference results from the electromagnetic wire or signal cable
connection between the source and the sensor. Interference along the cable the interference is transmitted from one
unit to another. Conducted interference often affects the power supply of the device, but can be controlled by a filter.
Radiated interference may affect any signal path in the device, and is difficult to shield.
Effective measures should be taken for the power system to prevent electric grid interference.
The working ground of the routers should be properly separated and kept as far as possible from the grounding
device of the power device or the anti-lightning grounding device.
Keep the device away from high-power radio transmitter, radar transmitting station, and high-frequency
large-current device.
Measures must be taken to isolate static electricity.
2.3 Precaution for Fiber Connection
Before connecting the fibers, you should ensure that the type of optical connector and the type of fibers match the type
of the optical interface used. Moreover, you should pay attention to the Tx and Rx directions of the fiber. The Tx end of
this device should be connected to the Rx end of the peer device, and the Rx end of this device to the Tx end of the
peer device.

Installing a Fan Module
1) Take out a new fan module from the fan module box.
2) Hold the handle at the end of the fan module. Insert the fan module to the chassis slowly along the guide rail until it
is fully seated, and make sure that it is in good contact with the slot.
3) Tighten the captive screws with a screwdriver to fix the fan module in the switch chassis.

Insert the fan module smoothly. Pay attention to the direction of the fan panel to avoid wrong insertion.
If the position is not proper, withdraw the inserted module and re-insert it.
If the screws cannot be tightened, it is probably because the fan module is not fully inserted. Please check it
carefully.
