Preparing for installation

The H3C S6520-EI Switch Series includes the following models:

• S6520-42QF-EI.

• S6520-48S-EI.

• S6520-52QF-EI.

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.

• Before cleaning the switch, unplug all power cords from 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 good 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, including power modules and fan trays, wear an ESD wrist strap to

avoid damaging the units.

Examining the installation site

The switch must be used indoors.

Mount your switch in a rack and make sure:

• Adequate clearance is reserved at the air inlet and exhaust vents for ventilation.

• The rack has a good ventilation system.

• Identify the hot aisle and cold aisle at the installation site, and make sure ambient air flows into

the switch from the cold aisle and exhausts to the hot aisle.

• Identify the airflow designs of neighboring devices, and prevent hot air flowing out of the bottom

device from entering the top device.

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

• The rack 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 appropriate temperature and humidity in the equipment room.

• Lasting high relative humidity can cause poor insulation, electricity leakage, mechanical

property change of materials, and metal corrosion.

2

• Lasting low relative humidity can cause washer contraction and ESD and cause problems

including loose mounting 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 of different switch models, see "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.

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, use the following guidelines:

• 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.

3

Laser safety

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.

The switch is a Class 1 laser device.

Installation tools

The installation tools are not provided with the switch. Prepare them yourself.

• Phillips screwdriver

• ESD wrist strap

4

Installing the switch

CAUTION:

Keep the tamper-proof seal on a mounting screw on the chassis cover intact, and if you want to

open the chassis, contact H3C for permission. Otherwise, H3C shall not be liable for any

consequence caused thereby.

Attaching the mounting brackets, chassis rails, and

grounding cable to the chassis

The switch has two mounting positions for mounting brackets: network port-side mounting position

and power module-side mounting position.

The switch has one primary grounding point (with a grounding sign) and two auxiliary grounding

points. Use the primary grounding point whenever possible. If the primary grounding point fails or is

not suitable for the installation site, use one of the auxiliary grounding points.

Figure 5 Mounting bracket installation positions and grounding points

(1) Auxiliary grounding point 2 (2) Power module-side mounting position for mounting brackets

(3) Primary grounding point (4) Auxiliary grounding point 1

(5) Network port-side mounting position for mounting brackets

Attaching the mounting brackets and chassis rails to the chassis

1. Align the mounting brackets with the screw holes in the power module-side mounting position

(see Figure 6) or net

work port-side mounting position (see Figure 7).

2. Use M4 screws (supplied with the switch) to attach the mounting brackets to the chassis.

3. Align the chassis rails with the mounting holes in the chassis:

{ If the mounting brackets are in the power module-side mounting position, align the chassis

rails with the screw holes at the front of the side panels (see Figure 6).

{ If the mounting brackets are in the network port-side mounting position, align the chassis

rails with the screw holes at the rear of the side panels (see Figure 7).

4. Use M4 screws (supplied with the switch) to attach the chassis rails to the chassis.

7

NOTE:

Secure the mounting brackets and chassis rails to both sides of the chassis in the same way.

Connecting the grounding cable to the chassis

CAUTION:

The primary grounding point and auxiliary grounding point 1 are located on the left side panel. If you

use one of these grounding points, you must connect the grounding cable to the grounding point

before you mount the switch in the rack.

To connect the grounding cable to a chassis grounding point, for example, the primary grounding

point:

1. Choose a grounding point.

2. Unpack the grounding cable and grounding screws.

3. Align the two-hole grounding lug at one end of the cable with the grounding holes of the

grounding point, insert the grounding screws into the holes, and tighten the screws with a

screwdriver to attach the grounding lug to the chassis, as shown in Figure 6.

Figure 7 Attaching the mounting brackets/chassis rails to the chassis (network port-side

mounting position for mounting brackets)

NOTE:

As a best practice, use the primary grounding point or auxiliary grounding point 1 because the

grounding cable and grounding screw that come with the switch are suitable only for these two

grounding points.

Attaching the slide rails to the rack

1. Identify the rack attachment position for the slide rails, and mark cage nut installation positions

on the rack posts.

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

3. Align the screw holes in one slide rail with the cage nuts in the rack post on one side, and use

screws (user supplied) to attach the slide rail to the rack, as shown in Figure 8.

4. Rep

eat the preceding step to attach the other slide rail to the rack post on the other side.

Keep the two slide rails at the same height so the slide rails can attach into the chassis rails.

Figure 8 Installing the slide rails

9

Mounting the switch in the rack

This task requires two people.

To mount the switch in the rack:

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

2. Verify that the mounting brackets and chassis rails have been securely attached to the switch

chassis.

3. Verify that the slide rails have been correctly attached to the rear rack posts.

4. Install cage nuts (user-supplied) to the front rack posts and make sure they are at the same

level as the slide rails.

5. Supporting the bottom of the switch, align the chassis rails with the slide rails on the rack posts,

as shown in Figure 9. Wo

rk with another person to slide the chassis rails along the slide rails

until the mounting brackets are flush with the rack posts.

6. Use screws (user-supplied) to attach the mounting brackets to the rack, as shown in Figure 10.

To s

ecure the switch in the rack, make sure the front ends of the slide rails reach out of the

chassis rails.

Figure 9 Mounting the switch in the rack (1)

Figure 10 Mounting the switch in the rack (2)

Grounding the switch

WARNING!

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

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 (commonly known as PGND). You must securely connect this

chassis ground to the earth so the faradism and leakage electricity can be safely released to the

earth to minimize EMI susceptibility of the switch.

You can ground a switch by using a grounding strip at the installation site or the AC power cord

connected to the switch.

NOTE:

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

Grounding the switch with a grounding strip

WARNING!

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

fire main or lightning rod.

If a grounding strip is available at the installation site, connect the grounding cable to the grounding

strip.

To connect the grounding cable:

11

1. Attach the two-hole grounding lug at one end of the grounding cable to a grounding point on the

switch chassis (see "Connecting the grounding cable to the chassis").

2. Remove the

hex nut of a grounding post on the grounding strip.

3. Attach the ring terminal at the other end of the grounding cable to the grounding strip through

the grounding post, and fasten the ring terminal with the removed hex nut.

Figure 11 Connecting the grounding cable to a grounding strip

(1) Hex nut (2) Ring terminal

(3) Grounding post (4) Grounding strip

NOTE:

• As a best practice, use the primary grounding point or auxiliary grounding point 1, because the

grounding cable and grounding screw provided with the switch are applicable only to these two

grounding points.

• To use auxiliary grounding point 2 on the switch, prepare a grounding cable yourself. The

connection method is the same as connecting to the other two grounding points.

Grounding the switch by using the AC power cord

If the installation site has no grounding strips, you can ground an AC-powered switch through the

protective earth (PE) wire of the power cord, but must make sure:

• The power cord has a PE terminal.

• The ground contact in the power outlet is securely connected to the ground in the power

distribution room or on the AC transformer side.

• The power cord is securely connected to the power outlet.

NOTE:

If the ground contact in the power outlet is not connected to the ground, report the problem and

reconstruct the grounding system.

12

NOTE:

To guarantee the grounding effect, use the grounding cable provided with the switch to connect to

the grounding strip in the equipment room as long as possible.

Installing/removing a fan tray

CAUTION:

To ensure good ventilation for the switch:

• Install two fan trays of the same model on the switch.

• Do not operate the system with one failed fan tray for more than 24 hours.

• Do not remove the failed fan tray until you are ready for replacing it.

• Do not operate the system without any fan tray for more than 2 minutes.

• Do not operate the system outside of the temperature range 0°C to 45°C (32°F to 113°F)

degrees.

Installing a fan tray

CAUTION:

To prevent damage to the fan tray or the connectors on the backplane, insert the fan tray gently. If

you encounter a hard resistance while inserting the fan tray, pull out the fan tray and insert it again.

Select appropriate fan trays as needed. For the optional fan trays and their specifications, see "Fan

trays."

13

To install a fan tray:

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

2. Unpack the fan tray and verify that the fan tray model is correct.

3. Grasp the handle of the fan tray with one hand and support the fan tray bottom with the other,

and slide the fan tray along the guide rails into the slot until the fan tray seats in the slot and has

a firm contact with the backplane (see callout 1 in Figure 13).

4. Fasten the captive screw on the fan tray

with a Philips screwdriver until the fan tray is securely

attached in the chassis (see callout 2 in Figure 13).

If the captive screw cannot be tightly fastened, verify the installation of the fan tray.
