Preparing for installation

The H3C SecPath M9000 Multi Service Security Gateway Series includes the following models:

• M9006.

• M9010.

• M9010-GM.

• M9014.

Safety recommendations

To avoid bodily injury and equipment damage, read all safety recommendations carefully before

installation. Note that the recommendations do not cover every possible hazardous condition.

General safety recommendations

• Keep the gateway clean and dust-free.

• Do not place the gateway on a moist area, and avoid liquid flowing into the gateway.

• Make sure the ground is dry and flat and anti-slip measures are in place.

• Keep the gateway and installation tools away from walk areas.

• Do not wear loose clothing, jewelry (for example, necklace) or any other things that could get

caught in the chassis when you install and maintain the gateway.

Electricity safety

• Clear the work area of possible electricity hazards, such as ungrounded power extension

cables, missing safety grounds, and wet floors.

• Locate the emergency power-off switch in the room before installation so you can quickly shut

power off when an electrical accident occurs.

• Unplug all external cables, including power cords, before moving the chassis.

• Do not work alone when the gateway has power.

• Always verify that power has been disconnected from a circuit.

Handling safety

CAUTION:

Do not hold the handle of the fan tray, power module, or back cover of the chassis, or the air vents o

f

chassis to move the gateway. Any attempt to move the gateway with these parts might cause

equipment damage and even bodily injury.

When you move the gateway, follow these guidelines:

• Remove all external cables, including the power cords, before moving the chassis.

• Moving the chassis requires at least two people, and you can use a mechanical lift as needed.

• Lift and put down the chassis slowly and never move suddenly.

• Hold the handles of the chassis.

2

ESD prevention

To prevent the electric component from being damaged by electrostatic discharge (ESD), follow

these guidelines:

• Ground the gateway correctly. For how to ground your gateway, see "Grounding the gateway."

• Always wear an ESD wrist strap and make sure it is correctly grounded when installing FRUs.

For how to use an ESD wrist strap, see "Attaching an ESD wrist strap."

• Hold a PCB by its edges. Do not touch any electronic components or printed circuit.

• Put cards away in antistatic bags for future use.

Laser safety

WARNING!

Do not stare into any fiber port or view directly with non-attenuating optical instruments when the

gateway is operating. The laser light emitted from the fiber port might hurt your eyes.

Examining the installation site

The gateway must be used indoors. To ensure the correct operation and long service life of your

gateway, the installation site must meet the requirements in this section.

Weight support

Make sure the floor can support the total weight of the rack, chassis, and accessories. Additionally,

the floor loading plan must also consider system expansion, such as adding more cards. For more

information, see "Appendix A Chassis views and technical specifications."

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.

To ensure the correct operation of the gateway, make sure the room temperature meets the

requirements in Table 1.

Table 1

Temperature requirements

Temperature Range

Operating temperature 0°C to 45°C (32°F to 113°F)

Storage temperature –40°C to +70°C (–40°F to +158°F)

Humidity

Maintain appropriate humidity in your equipment room, as described in Table 2.

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

property change of materials, and corrosion of metal parts.

3

• Lasting low relative humidity is likely to result in loose screws due to washer contraction, and

even electrostatic discharge (ESD), which causes the circuits to fail.

Table 2 Humidity requirements

Humidity Range

Operating humidity 10% 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.

)

Dust particles

≤ 3 x 10

(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 Table 4.

EMI

Electromagnetic interference (EMI) might be coupled from the source to the gateway through the

following coupling mechanisms:

• Capacitive coupling

• Inductive coupling

• Radiative coupling

• Common impedance coupling

• Conductive coupling

To prevent EMI, take the following actions:

• Filter interference from the power grid.

• Keep the gateway grounding facilities away from grounding and lightning protection facilities of

other devices.

4

• Keep the gateway far away from radio transmitting stations, radar stations, and high-frequency

devices to make sure the EMI levels do not exceed the compliant range.

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

Grounding

Using a good grounding system to protect your gateway against lightning shocks, interferences, and

ESD is essential to the operating reliability of your gateway.

Make sure the resistance between the chassis and the ground is less than 1 ohm. For more

information about grounding the gateway, see "Grounding the gateway."

Power

Perform the following tasks to meet the power requirements:

1. Calculate the system power consumption.

The system power consumption varies by card type and density. For more information about

system power consumption calculation, see "Appendix A Chassis views and technical

specifications."

2. Select po

wer modules and identify the number of power modules.

The total maximum output power of all power modules must be higher than the system power

consumption. For more information about available power modules, see "Appendix B FRUs

and compatib

ility matrixes."

3. Verify that the power system at the installation site meets the requirements of the power

modules, including the input method and rated input voltage.

Cooling

Plan the installation site for adequate ventilation.

• The installation site has a good cooling system.

• The rack for the gateway has a good cooling system.

• Leave a minimum clearance of 10 cm (3.94 in) around the inlet and outlet air vents.

Figure 1 sho

ws the airflow through the M9010 or M9010-GM chassis. Figure 2 shows the airflow

through the M9006 chassis. M9014 and M9006 have the same airflow designs.

• The rack is sturdy and securely grounded.

• The rack has enough space to install the gateway and no debris exists inside or around the

rack.

• The mounting position of the gateway on the rack has been identified. As a best practice, install

the gateway at the bottom of the rack.

• The total height of the devices to be installed in the rack is no higher than the available

installation height of the rack and enough clearance is reserved for cable routing. Make sure the

heaviest device is placed at the bottom of the rack.

• The gateway is ready for installation and has been carried to a place near the rack and

convenient for moving.

Attaching slide rails to the rack

IMPORTANT:

To ensure stability of the rack, install the slide rails to the lowest possible position when installing a

single gateway in the rack. To install multiple devices on the rack, mount the heaviest device at the

bottom of the rack.

If the rack has slide rails, skip this section.

Before you attach slide rails to the rack, verify that the slide rails can support the weight of the

gateway. For the weights of the M9000 gateways, see "Appendix A Chassis views and technical

specifications."

As a be

st practice, order H3C slide rail LSTM2KSGD0. The slide rail has an adjustment range of 500

mm (19.69 in) to 800 mm (31.50 in).

Slide rail installation varies by rack type. The following installation procedure is for your reference

only.

To install slide rails:

1. Read the signs on the slide rails (see Table 7) to ide

ntify the left and right slide rails.

Sign Meaning Remarks

F/L Front end of the left slide rail Mount this end to the front left rack post.

F/R Front end of the right slide rail Mount this end to the front right rack post.

2. Mark the slide rail installation positions on the rack posts.

The square holes on the rack post are divided into rack units (RUs). One RU has two standard

installation holes and one auxiliary installation hole in the middle. The space between a

standard installation hole and an auxiliary installation hole is wider than the space between two

adjacent standard installation holes.

a. Align the bottom edge of the slide rail with the middle of the narrower metal area between

holes, as shown in Figure 4.

b. Mark the uppermo

st and the lowermost installation holes on each rack post. Each rack post

requires six screws to attach the slide rail.

5. Keep the slide rail horizontally and adjust its length until the installation holes on the rear end of

the slide rail touch the cage nuts on the rear rack post. Then fasten a screw in each installation

hole.

Install a screw in each mounting hole of the slide rail to ensure its weight bearing capacity.

6. Repeat steps 4 and 5 to install the other slide rail. Make sure the two slide rails are at the same

height so that the gateway can be placed on them horizontally.

Installing cage nuts for attaching mounting brackets

1. Align the bottom edge of a mounting bracket with the weight-bearing surface of a slide rail.

2. Determine and mark the cage nut installation holes on the rack post. Each installation hole on

the mounting bracket requires a cage nut.

3. Install cage nuts on the marked square holes on the front rack post.

4. Repeat steps 1, 2, and 3 to install cage nuts on another front rack post.

Attaching cable management brackets and

mounting brackets to the chassis

Before installing the gateway to the rack, install the cable management brackets and mounting

brackets shipped with the gateway. Cable management brackets (signal cable and power cord

management brackets) are used for cabling the gateway, and mounting brackets are used for

attaching the chassis to the rack.

Installing cable management brackets

The M9010 and M9010-GM gateways each have two cable management brackets—the signal cable

management brackets are installed at the upper part of the gateway, and the power cord

management brackets are installed at the lower part of the gateway. They are installed in the same

way. For more information, see Figure 8.

The M90

06 and M9014 gateways come with the signal cable management brackets secured to the

mounting brackets. The power cord management bracket of the M9006 gateway has a slightly

different structure than the M9006 and M9014, and is installed in a similar procedure. For more

information, see Figure 9.

12

The power cord management bracket installation procedure for the M9014, M9010, and M9010-GM

is the same.

To install a cable management bracket:

1. Unpack the cable management bracket from the accessory kit package.

2. Place the cable management bracket against the installation position on the chassis, and align

the screws with the mounting holes on the chassis, as shown in Figure 8.

3. Fasten th

e screws to secure the cable management bracket to the chassis.

Installing mounting brackets

Before installing the gateway to the rack, install the mounting brackets to the chassis. Marks L and R

are printed inside the mounting brackets to distinguish between the left and right mounting brackets.

To install the mounting brackets, face the front of the gateway, and attach the left and right mounting

brackets to the two sides of the gateway, as shown in Figure 10.

(Optional) Installing air filters

Air filters are installed at the air inlet vents to prevent dust from entering the chassis. If you have

ordered air filters, install the air filters before mounting the gateway to the rack.

14

Attaching air filters to an M9006/M9014 gateway

Air filters of an M9006/M9014 gateway are installed at the left of the chassis. The air filter installation

procedures on an M9006 and M9014 are the same.

To install an air filter on an M9006/M9014 gateway:

1. Put the air filter near the air inlet vents on the left of the chassis and insert the poisoning pins on

the air filter into the corresponding holes on the chassis.

2. Insert the screws into the screw holes on the air filter, and fasten them with a Phillips

screwdriver.

Figure 11 Attaching air filters to an M9006 gateway

Attaching air filters to an M9010/M9010-GM gateway

The air filter of an M9010 or M9010-GM gateway is installed at the lower part of the chassis front.

To install an air filter on an M9010 gateway:

1. Put the air filter near the air inlet vent on the lower part of the chassis front and insert the

poisoning pins on the air filter into the corresponding holes on the chassis.

2. Insert the screws into the screw holes on the air filter, and fasten them with a Phillips

screwdriver.

TIP:

• Install the power cord management bracket before you install an air filter for the M9010 or

M9010-GM gateway.

• Clean the air filter every three months to ensure correct ventilation and heat dissipation of the

gateway.

Mounting the gateway in the rack

WARNING!

To avoid device damage or even bodily injury, do not hold the handle of a fan tray or power module,

air vents, or the handle on the rear panel of the chassis to move the gateway.

To mount the gateway in the rack:

1. Move the chassis to face the rear of the chassis towards the front of the rack.

2. Use at least two people to lift the gateway by using the chassis handles or supporting the

bottom of the chassis until the bottom of the gateway is a little higher than the slide rails on the

rack.

As a best practice, use a mechanical lift for moving your gateway.

3. Place the gateway on the slide rails and slide the gateway along the slide rails until the

mounting brackets on the gateway touch the front rack posts, as shown in Figure 13.

After placin

g the switch on the slide rails, do not leave go of your hands immediately because

this might tip the switch, damaging the switch or even causing bodily injury.

16

Figure 13 Placing the chassis on the rack (M9006)

4. Use the screws to attach the mounting brackets to the rack.

If the mounting holes in the mounting brackets cannot align with the cage nuts on the rack,

verify that the bottom edge of the slide rail aligns with the middle of the narrower metal area

between holes and that the cage nuts are installed in the correct holes.

Figure 14 Securing the chassis to the rack (M9006)

Grounding the gateway

CAUTION:

• Before you use the gateway, ground the gateway correctly.

• Use the grounding cable (yellow-green grounding cable) that comes with your gateway.

• Make sure the grounding terminal of the rack is connected to the grounding strip in the equipment

room. Do not connect it to a fire main or lightning rod.

To ground the gateway:

1. Remove the grounding screws from the grounding holes at the rear of the chassis.

17

2. Use the grounding screws to attach the two-hole grounding lug of the grounding cable to the

chassis.

3. Remove the grounding screw from the grounding hole of the cabinet's grounding terminal.

4. Use the grounding screw to attach the ring terminal of the grounding cable to the grounding

terminal of the cabinet.

Installing FRUs

Attaching an ESD wrist strap

Every M9000 gateway comes with an ESD wrist strap. To minimize ESD damage to electronic

components, wear the ESD wrist strap and make sure it is correctly grounded when installing

modules.

To attach an ESD wrist strap:

1. Make sure the gateway is correctly grounded. For how to ground your gateway, see "Grounding

the gateway."

2. Put on the wri

st strap.

3. Tighten the wrist strap to keep good skin contact. Make sure the resistance reading between

your body and the ground is between 1 and 10 megohms.

4. Insert the grounding terminal of the ESD wrist strap into the ESD port on the gateway chassis.
