Preparing for installation
Safety recommendations
Safety symbols
When reading this document, note the following symbols:
WARNING means an alert that calls attention to important information that if not understood or
followed can result in personal injury.
CAUTION means an alert that calls attention to important information that if not understood or
followed can result in data loss, data corruption, or damage to hardware or software.
General safety recommendations
To avoid any equipment damage or bodily injury, read the following safety recommendations before
installation. Note that the recommendations do not cover every possible hazardous condition.
•Do not place the device on an unstable case or desk. The device might be severely damaged in
case of a fall.
•Make sure the ground is dry and flat and anti-slip measures are in place.
•Keep the chassis and installation tools away from walk areas.
•Keep the chassis clean and dust-free.
•Do not place the device near water or in a damp environment. Prevent water or moisture from
entering the device chassis.
•Ensure good ventilation of the equipment room and keep the air inlet and outlet vents of the device
free of obstruction.
•Make sure the operating voltage is in the required range.
•Use a screwdriver to fasten screws.
•To prevent condensation, unpack the device at least half an hour after you move the device from a
location below 0°C (32°F) to the equipment room, and power on the device at least 2 hours after
you move the device from a location below 0°C (32°F) to the equipment room.
Electrical safety
•Carefully examine your work area for possible hazards, such as moist floors, ungrounded power
extension cables, or missing safety grounds.
•Locate the emergency power-off switch in the room before installation. Shut off the power
immediately if an accident occurs.
•Unplug all the external cables (including power cables) before moving the chassis.

2
•Do not work alone when you operate the device with the device powered on.
•Always check that the power has been disconnected when you perform operations that require the
device to be powered off.
Laser safety
W
ARNING!
Do not stare into any fiber port when the device is powered on. The laser li
g
ht emitted from the optical fiber
might hurt your eyes.
•Before you disconnect the fiber connector, execute the shutdown command in interface view to
disable the optical source.
•Install the dust covers to the optical fiber connector to avoid connector damage.
Examining the installation site
The device can only be used indoors. To ensure correct operation and a long lifespan for your device, the
installation site must meet the requirements in this section.
Temperature and humidity
Maintain the temperature and humidity in the equipment room at acceptable levels.
•Lasting high relative humidity can cause poor insulation, electricity creepage, mechanical property
change of materials, and metal corrosion.
•Lasting low relative humidity can cause washer contraction and ESD and bring problems including
loose captive screws and circuit failure.
•High temperature can accelerate the aging of insulation materials and significantly lower the
reliability and lifespan of the switch.
To ensure correct operation of the device, the equipment room must meet the temperature and humidity
requirements listed in Table 1.
Table 1 Temperature/humidity requirements in the equipment room
Tem
p
erature Relative humidit
y
0°C to 45°C (32°F to 113°F) 5% to 95%, noncondensing
Cleanliness
Dust buildup on the chassis can result in electrostatic adsorption, which causes poor contact of metal
components and contact points, especially when indoor relative humidity is low. In the worst case,
electrostatic adsorption can cause communication failure. To ensure correct operation, the equipment
room must meet the dust concentration requirements listed in Table 2.

Table 2 Dust concentration limit in the equipment room
Substance Concentration limit (

Dust particles ≤3 x 104
(No visible dust on desk in three days)
NOTE:
Dust particle diameter ≥5 μm
To eliminate corrosion and premature aging of components, the equipment room must also meet limits on
salts, acids, and sulfides, as shown in Table 3.

Cooling
The device uses left to right airflow for heat dissipation. Plan the installation site for adequate ventilation.
•H3C recommends that you leave a minimum of 10 cm (3.94 in) of clearance around the air vents.
•Make sure the rack or workbench has a good ventilation system.
Figure 1 Airflow through the chassis
ESD prevention
To prevent electrostatic discharge (ESD), follow these guidelines:
•Ground the device reliably.
•Take dust-proof measures for the equipment room. For more information, see "Cleanliness."
•Maintain the humidity and temperature at acceptable levels. For more information, see
"Temperature and humidity."

4
•Always wear an ESD wrist strap. Make sure the wrist strap makes skin contact and is reliably
grounded when installing the transceiver module.
The ESD wrist strap is not provided with the device. Order it yourself.
To attach an ESD wrist strap:
1. Wear the wrist strap on your wrist.
2. Lock the wrist strap tight around your wrist to maintain good contact with the skin.
3. Secure the wrist strap lock and the alligator clip lock together.
4. Attach the alligator clip to the rack.
5. Make sure the rack is reliably grounded.

EMI
All electromagnetic interference (EMI) sources, from outside or inside of the device and application
system, adversely affect the device in the following ways:
•A conduction pattern of capacitance coupling.
•Inductance coupling.
•Electromagnetic wave radiation.
•Common impedance (including the grounding system) coupling.
To prevent EMI, perform the following tasks:
•If AC power is used, use a single-phase three-wire power receptacle with protection earth (PE) to
filter interference from the power grid.

5
•Keep the device far away from radio transmitting stations, radar stations, and high-frequency
devices.
•Use electromagnetic shielding, for example, shielded interface cables, when necessary.
Lightning protection
To better protect the device from lightning, follow these guidelines:
•Make sure the grounding cable of the chassis is reliably grounded.
•Make sure the grounding terminal of the AC power receptacle is reliably grounded.
•Install a lightning protector at the input end of the power supply to enhance the lightning protection
capability of the power supply.
