Preparing for installation

Safety recommendations

To avoid any equipment damage or bodily injury caused by improper use, observe these rules:

• Before cleaning the switch, remove the power cord of the switch. 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 ventilation vents of the switch free of

obstruction.

• Make sure the operating voltage is as required.

• To avoid electrical shocks, do not open the chassis when the switch is operating or when the switch

is just powered off.

• When replacing interface cards, wear an ESD-preventive wrist strap to avoid damaging the cards.

Examining the installation site

The S5120-EI Switch Series 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 exhaust vents for ventilation.

• The rack or workbench has a good ventilation system.

• The rack is sturdy enough to support the device and its accessories.

• The rack or workbench is well earthed.

To ensure normal 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 as described in "Technical specifications."

• 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.

Cleanness

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 1 Dust concentration limit in the equipment room

Substance Unit Concentration limit

Dust

Particles/m³

≤ 3 x 10

(no visible dust on the tabletop within

NOTE

The dust particle size ≥ 5 μm.

The equipment room must also meet strict limits on salts, acids, and sulfides to eliminate corrosion and

premature aging of components, as shown in Table 2.

EMI

All electromagnetic interference (EMI) sources, from outside or inside of the switch and application

system, adversely affect the switch in a conduction pattern of capacitance coupling, inductance coupling,

electromagnetic wave radiation, or common impedance (including the grounding system) coupling. To

prevent EMI, take the following actions:

• As the AC power system is a TN system, use a single-phase three-wire power receptacle with

Protection Earth (PE) to filter interference from the power grid.

• Keep the switch far from radio transmitting stations, radar stations, and high-frequency devices.

• Use electromagnetic shielding when necessary, for example, use shielded interface cables.

• Route interface cables only indoors to prevent signal ports from getting damaged by overvoltage or

overcurrent caused by lightning strikes.

Laser safety

The S5120-EI Switch Series is a line of Class 1 laser devices.

CAUTION:

hen a fiber port on an S5120-EI switch is operatin

, do not stare into the fiber port because the laser

light emitted from the optical fiber might hurt your eyes.

Installation tools

• Flathead screwdriver

• Phillips screwdriver

• Needle-nose pliers

• Wire-stripping pliers

• Diagonal pliers

• ESD-preventive wrist strap

• Blow dryer

All these installation tools are user supplied.

Installing the switch

ARNING!

Keep the tamper-proof seal on a mountin

screw on the chassis cover intact, and if you want to open the

chassis, contact the local agent of H3C for permission. Otherwise, H3C shall not be liable for any

consequence caused thereby.

information, see "Setting up an IRF fabric."

Installing the switch into a 19-inch rack

Installation methods

You can install a switch into a 19-inch standard rack in one of the following ways:

• Use front mounting brackets

• Use front mounting brackets and a rack-shelf

• Use front mounting brackets and rear mounting brackets

The installation methods of a switch depend on the depth of the switch. For the specific installation

methods, see Table 3.

NOTE:

For a switch with a depth greater than 300 mm (11.81 in), the front mounting brackets only secure the

switch rather than bear its weight.

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

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

IMPORTANT:

• Ensure good ventilation and a space of 10 cm (3.94 in) around the chassis for heat dissipation.

• Avoid heavy objects on the switch.

Grounding the switch

CAUTION:

• Correctly connecting the switch grounding cable is crucial to lightning protection and EMI protection.

• The power input and grounding terminals in this section are for illustration only.

The power input end of the switch has a noise filter, whose central ground is directly connected to the

chassis to form the chassis ground. You must securely connect this chassis ground to the earth so that the

faradism and leakage electricity can be safely released to the earth to minimize EMI susceptibility of the

switch.

You have the following approaches to grounding the switch depending on the grounding conditions

available at the installation site:

• Grounding the switch with a grounding strip

• Grounding the switch with a grounding conductor buried in the earth ground

• Grounding the switch in other grounding environments

Grounding the switch with a grounding strip

CAUTION:

Connect the grounding cable to the grounding system in the equipment room. Do not connect it to a fire

main or lightning rod.

The S5120-EI Switch Series has a grounding point (with a grounding sign) at the rear panel.

To connect the grounding cable:

1. Remove the grounding screw from the rear panel of the switch chassis.

2. Attach the grounding screw to the ring terminal of the grounding cable.

3. Use a screwdriver to fasten the grounding screw into the grounding screw hole.
