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-W6910-64C 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-W6910-64C, 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
damaging the circuit board, but cannot prevent any static electricity on clothes.
2.1.5 Laser Safety
Among the modules supported by the M2-W6910-64C, there are a great number of optical modules that are Class I
laser product.
Precautions:
When a fiber transceiver works, ensure that the port has been connected with a fiber or has been covered by a
dust cap so as to keep out dust and prevent it from burning your eyes.
Do not stare at any fiber port.
Do not stare at any fiber port under any circumstances, as this may cause permanent damage to your eyes.
2.2 Installation Site Requirements

site must meet the following requirements.
2.2.1 Rack Mounting Requirements
Make sure the cabinet complies with the following conditions if the M2-W6910-64C is installed in the cabinet:

Hardware Installation and Reference Guide Preparation before Installation
- 12 -
Install the switch in an open cabinet as much as possible. If you install the switch inside a closed cabinet, be sure
that the cabinet has a good ventilation and heat dissipation system.
Be sure that the cabinet is firm enough to bear the weight of the M2-W6910-64C and its installation accessories.
Be sure that the dimensions of the cabinet is appropriate for installation of the M2-W6910-64C 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-W6910 series 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-W6910-64C, 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.
Temperature and humidity requirements of the M2-W6910-64C:

The ambient temperature and humidity are measured at the point that is 1.5 m above the floor and 0.4 m before
the device when there is no protective plate in front or at the back of the device rack.
2.2.4 Cleanness Requirements
Dust poses the top threat to the running of the device. The indoor dust falling on the device may be adhered by the
static electricity, causing poor contact of the metallic joint. Such electrostatic adherence may occur more easily when
the relative humidity is low, not only affecting the service life of the device, but also causing communication faults. The
following table shows the requirements for the dust content and granularity in the equipment room.

The Average refers to the average limit of harmful gas in one week. The Maximum value is the upper limit of the
harmful gas in one week, and maximum value can last for up to 30 minutes every day.
2.2.5 System Grounding Requirements
A good grounding system is the basis for the stable and reliable operation of the M2-W6910-64C. It is the key to prevent
lightning stroke and resist interference. Please carefully check the grounding conditions on the installation site
according to the grounding requirements, and perform grounding properly as needed.
Safety Grounding
The device using AC power supply must be grounded by using the yellow/green safety grounding cable. Otherwise,
when grounding fault happens in the high voltage circuit inside the device, electric shock may occur.
The building installation shall provide a means for connection to protective earth, and the device is to be
connected to that means.
Lightning Grounding
The lightning protection system of the facility is an independent system that consists of the lightning rod, down lead
conductor and the connector to the grounding system, which usually shares the power reference ground and
yellow/green safety cable ground. The lightning discharge ground is for the facility only, not for the device.
For lightning protection, refer to Appendix B.
EMC Grounding
The ground required for EMC design includes shielding ground, filter ground, noise and interference suppression, and
level reference. All the above constitute the comprehensive grounding requirements. The grounding resistance should
be less than 1Ω. There is one grounding connector at the right bottom of the chassis of M2-W6910 series switches. The
grounding connector is pasted with conspicuous warning labels.

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.
