Safety recommendations

To avoid any equipment damage or bodily injury caused by improper use, read the following safety
recommendations before installation. Note that the recommendations do not cover every possible
hazardous condition.

 Before cleaning the switch, unplug all power cords. Do not clean the switch with wet cloth or

liquid.

 Do not place the switch near water or in a damp environment. Prevent water or moisture from

entering the switch chassis.

 Do not place the switch on an unstable case or desk. The switch might be severely damaged in

case of a fall.

 Ensure proper ventilation of the equipment room and keep the air inlet and outlet vents of the

switch free of obstruction.

 Make sure the operating voltage is in the required range.
 To avoid electrical shocks, do not open the chassis while the switch is operating or when the

switch is just powered off.

 When replacing FRUs, wear an ESD wrist strap to avoid damaging the units.

Examining the installation site

The switch must be used indoors. You can mount your switch in a rack or on a workbench, but make
sure:

 Adequate clearance is reserved at the air inlet and outlet vents for ventilation.
 The rack or workbench has a good ventilation system.
 The rack is sturdy enough to support the switch and its accessories.
 The rack or workbench is reliably grounded.

To ensure correct operation and long service life of your switch, install it in an environment that meets
the requirements described in the following subsections.

Temperature/humidity

Maintain temperature and humidity in the equipment room in the acceptable range.
 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.

For the temperature and humidity requirements, see "Appendix A Chassis views and technical

specifications."

Cleanliness

Dust buildup on the chassis might 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.

Table 3 Dust concentration limit in the equipment room

The equipment room must also meet limits on salts, acids, and sulfides to eliminate corrosion and
premature aging of components, as shown in Table 4.

Table 4 Harmful gas limits in the equipment room

WARNING!

Do not stare into any fiber port when the switch has power. The laser light emitted from the optical
fiber might hurt your eyes.

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.
 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.

Laser safety

The switch is Class 1 laser device.

Installation tools

 Flathead screwdriver
 Phillips screwdriver
 Needle-nose pliers
 Wire-stripping pliers
 Diagonal pliers
 ESD wrist strap
 Blow dryer

All these installation tools are user supplied.

Rack-mounting the switch

This task requires two persons.
To mount the switch in a rack:

1. Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.

2. Verify that the rack is reliably grounded and can support the weight of the switch chassis and all

its accessories.

3. Verify that the mounting brackets have been secured to the switch chassis.

4. Install cage nuts (user-supplied) in the mounting holes in the rack posts.

5. One person holds the switch chassis and aligns the oval holes in the brackets with the mounting

holes in the rack posts, and the other person attaches the mounting brackets with M6 screws
(user-supplied) to the rack, as shown in Figure 11 or Figure 12.

NOTE:

If a rack shelf is available, you can put the switch on the rack shelf, slide the switch to an appropriate
location, and attach the switch to the rack with the mounting brackets.

To mount the switch on a workbench:

1. Verify that the workbench is sturdy and reliably grounded.

2. Place the switch with bottom up, and clean the round holes in the chassis bottom with dry cloth.

3. Attach the rubber feet to the four round holes in the chassis bottom.

4. Place the switch with upside up on the workbench.

Grounding the switch
