a fan tray, a power supply, or a module, or the air vents of the chassis
to
move the switch
. Any attempt to move the switch with these parts might cause equipment damage
and even bodily injury.
Remove power supplies, modules, and all external cables, including the power cords, before moving
the chassis. As a best practice, use a mechanical lift, such as forklift truck, to move the chassis.
If no mechanical lift is used, follow these guidelines to move the chassis:
•
Cooperate with multiple people to move the chassis.
•
Lift the chassis by using the chassis handles or by supporting the bottom from the two sides.
•
Lift and put down the chassis slowly and never move suddenly.

1-2
ESD prevention
To prevent the electric component from being damaged by electrostatic discharge (ESD), follow
these guidelines:
•
Ground the switch reliably. For how to ground your switch, see "Grounding the switch."
•
Always wear an ESD wrist strap and make sure it is reliably grounded when installing
removable components. For how to use an ESD wrist strap, see "Attaching an ESD wrist strap."
•
Hold a module by its edges. Do not touch electronic components or the printed circuit board
directly with your hands.
•
If you are not to use a module, put it in an antistatic bag and keep it secure.
Laser safety
WARNING
!
Disconnected optical fibers or transceiver
modules might emit invisible laser light. Do not stare into
beams or view directly with optical instruments when the switch is operating.
The switch is a Class 1 laser product.
Examining the installation site
The switch must be used indoors. To ensure correct operation and long service life of your switch,
make sure the installation site meets the following requirements.
Weight support
Make sure the floor or ground at the installation site can support the combined weight of the switch
and the rack. The total weight of the switch includes the chassis and its components (for example,
modules and power supplies) and accessories. For the weights of the switch and its components,
see "Weights and dimensions."
To mount the switch in a rack, select slide rails that can support the total weight of the switch.
To assess the load-bearing requirements for the floor and slide rails, take potential system expansion
(for example, adding more modules) also in consideration.
Temperature
CAUTION:
If condensation appears on the chassis when you move it to a high
-temperature environment, dry
the chassis before powering it on to avoid short circuits.
If the temperature in the equipment room is too high, too low, or changes dramatically, the device
reliability is reduced and its service lifetime is shortened. For long-term, highly available operation of
the device, make sure temperature and humidity in the equipment room meets the requirements
described in Table1-1.
Table1-1 Temperature requirements
Temperature Range
Operating temperature 0°C to 40°C (32°F to 104°F)

1-3
Temperature Range
Storage temperature –40°C to +70°C (–40°F to +158°F)
Humidity
Maintain appropriate humidity in your equipment room, as described in Table1-2.
•
Lasting high relative humidity can cause poor insulation, electricity leakage, mechanical
property change of materials, and metal corrosion.
•
Lasting low relative humidity can cause washer contraction and ESD and cause problems
including loose mounting screws and circuit failure.
Table1-2 Humidity requirements
Humidity Range
Operating humidity 5% to 95%, noncondensing
Storage humidity 5% to 95%, noncondensing
Cleanliness
Dust buildup on the chassis might result in electrostatic adsorption, which causes poor contact of
metal components and contact points. In the worst case, electrostatic adsorption can cause
communication failure.
Table1-3 Dust concentration limit in the equipment room
Substance Concentration limit (particles/m3)
Dust particles ≤ 3 x 104
(No visible dust on desk in three days)
NOTE:
Dust particle diameter ≥ 5 µm
The equipment room must also meet limits on salts, acids, and sulfides to eliminate corrosion and
premature aging of components, as shown in Table1-4.
Table1-4 Harmful gas limits in the equipment room
Gas Max. (mg/m3)
SO20.2
H2S 0.006
NH30.05
Cl20.01
EMI
All electromagnetic interference (EMI) sources, from outside or inside of the switch and application
system, adversely affect the switch in the following ways:
•
A conduction pattern of capacitance coupling.

1-4
•
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.
•
Keep the switch far away from radio transmitting stations, radar stations, and high-frequency
devices.
•
Use electromagnetic shielding, for example, shielded interface cables, when necessary.
Grounding
Using a good grounding system to protect your switch against lightning shocks, interferences, and
ESD is essential to the operating reliability of your switch.
Make sure the equipment room grounding network has a resistance value less than 1 ohm.
For more information about grounding the switch, see "Grounding the switch."
Power
Perform the following tasks to provide power as required by the switch:
1. Calculate the system power consumption.
The system power consumption varies by module types and quantities. For more information
about the system power consumption, see "Module power consumption and system power
consumption."
2. Identify the number of power supplies based on the system power consumption.
The total maximum output power of all power supplies must be higher than the system power
consumption. For more information about available power supplies, see "Power supplies."
3. Verify that the power system at the installation site meets the requirements of the power
supplies, including the input method and rated input voltage. For more information about power
supply specifications, see "Power supplies."
