Preparing for installation

The S6550XE-HI switch series has one model: S6550XE-56HF-HI.

The S6550X-HI switch series has one model: S6550X-32Q-HI.

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, remove 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.

·     To avoid ESD damage, always wear an ESD wrist strap when replacing a power supply or fan tray.

Examining the installation site

You must install the switch indoors and make sure the following requirements are met:

·     Adequate clearance is reserved at the air inlet and outlet 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 neighboring devices 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 temperature and humidity in the equipment room at acceptable ranges.

·     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 issues 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, see hardware information and specifications for the switch.

Cleanliness

Dust buildup on the chassis might cause electrostatic adsorption and dust corrosion, resulting in poor contact of metal connectors and contact points. This might shorten the device's lifetime and even cause device failure in the worst case. Table 1 describes the dust concentration limits in the equipment room.

To maintain cleanliness in the equipment room, follow these guidelines:

·     Keep the equipment room away from pollution sources. Do not smoke, eat, or drink in the equipment room.

·     Use double-glazed windows and seal doors and windows with dust-proof rubber strips. Use screen doors and window screens for doors and windows open to the outside and make sure the external windows are air tight.

·     Use dustproof materials for floors, walls, and ceilings and use wallpaper or matt paint that does not produce powders.

·     Clean the equipment room regularly and clean the air filters of the rack each month.

·     Wear ESD clothing and shoe covers before entering the equipment room. Keep the ESD clothing and shoe covers clean and change them frequently.

Corrosive gas limit

Corrosive gases can accelerate corrosion and aging of metal components. Make sure the corrosive gases in the equipment room do not exceed the concentration limits as shown in Table 2.

CAUTION

CAUTION:

As a best practice, control the corrosive gas in the equipment room at the average concentration values. Make sure the corrosive gas will not be in their maximum allowable concentration values for over 30 minutes per day.

 

To control corrosive gases, use the following guidelines:

·     As a best practice, do not build the equipment room in a place with a high concentration of corrosive gases.

·     Make sure the equipment room is not connected to sewer, vertical shaft, or septic tank pipelines and keep it far away from these pipelines. The air inlets in the equipment room must be away from such pollution sources.

·     Use environmentally friendly materials to decorate the equipment room. Avoid using organic materials that contain harmful gases, such as sulfur or chlorine-containing insulation cottons, rubber mats, sound-proof cottons, and avoid using plasterboards with high sulfur concentration.

·     Place fuel (diesel or gasoline) engines separately. Do not place them in the same equipment room with the device. Make sure the air exhausted from the engines will not flow into the equipment room or towards the air inlets of the air conditioners.

·     Place batteries separately. Do not place them in the same room with the device.

·     Employ a professional company to monitor and control corrosive gases in the equipment room regularly.

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.

·     To prevent signal ports from getting damaged by overvoltage or overcurrent caused by lightning strikes, route interface cables only indoors.

Laser safety

WARNING

WARNING!

·     The switch is a Class 1M laser device.

·     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.

 

Installation tools

No installation tools are provided with the switch. Prepare the following tools yourself:

·     Flat-head screwdriver.

·     Phillips screwdriver.

·     ESD wrist strap.

·     Marker.

NOTE:

Use the same procedure to attach the mounting brackets and chassis rails to the two sides of the chassis.

 

Connecting the grounding cable to the chassis

CAUTION

CAUTION:

If you use a grounding point to ground the switch, you must connect the grounding cable to the grounding point before you mount the switch in the rack.

 

The switch provides a primary grounding point and auxiliary grounding point on the left panel. The primary grounding point has a grounding sign and the auxiliary grounding point does not.

The grounding cable connection procedure is the same for the primary and auxiliary grounding points. The following procedure connects the grounding cable to the primary grounding point.

To connect the grounding cable to the primary grounding point:

1.     Choose a grounding point as required.

When you install the mounting brackets at the port-side mounting position, choose the auxiliary grounding point. When you install the mounting brackets at the power supply-side mounting position, choose the primary grounding point.

2.     Unpack the grounding cable and grounding screws.

3.     Use the two grounding screws to attach the two-hole grounding lug of the grounding cable to the grounding holes at the grounding point. Use a screwdriver to fasten the screws. See Figure 13.

As a best practice, use a torque of 20 kgf-cm (1.96 Nm) to fasten the grounding screws.

Figure 13 Connecting the grounding cable to the primary grounding point

 

Attaching the slide rails to the rack

1.     Identify the slide rail installation position in the rack.

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 a rear rack post. Use user-supplied M6 screws to attach the slide rail to the post. See Figure 14.

As a best practice, use a torque of 30 kgf-cm (2.94 Nm) to fasten M6 screws.

4.     Repeat the preceding steps to attach the other slide rail to the other rear rack post.

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

Figure 14 Installing the slide rails

 

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 reliably 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.     Attach cage nuts (user-supplied) to the front rack posts and make sure they are at the same level as the slide rails.

5.     One person performs the following operations:

a.     Supporting the bottom of the switch, aligns the chassis rails with the slide rails on the rack posts.

b.     Pushes the switch slowly to slide the chassis rails along the slide rails until the mounting brackets are flush with the rack posts.

 

IMPORTANT

IMPORTANT:

If you use long slide rails to rack-mount the switch, make sure the front ends of the long slide rails reach out of the chassis rails for a maximum of 20 mm (0.79 in). If you use super-short slide rails to rack-mount the switch, make sure the front ends of the super-short slide rails reach inside the chassis rails for a minimum of 90 mm (3.54 in) after installation.

 

6.     Another person uses user-supplied M6 screws to attach the mounting brackets to the rack.

Figure 15 Mounting the switch in the rack (port-side mounting position for the mounting brackets)

 

Figure 16 Mounting the switch in the rack (power supply-side mounting position for the mounting brackets)

 

Grounding the switch

CAUTION

CAUTION:

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

·     Connect the grounding cable to the grounding system in the equipment room. Do not connect it to a fire main or lightning rod.

·     As a best practice to guarantee the grounding effect, use the grounding cable provided with the switch to connect to the grounding strip in the equipment room.

 

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.

To connect the grounding cable to a grounding strip:

1.     Attach the two-hole grounding lug of the grounding cable to a grounding point on the chassis. For more information, 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 of the grounding cable to the grounding post on the grounding strip, and secure the ring terminal to the grounding post with the hex nut.

NOTE:

The grounding terminals in this figure are for illustration only.

 

Installing and removing fan trays

CAUTION

CAUTION:

The switch has multiple fan tray slots. To ensure good ventilation of the switch, follow these guidelines to install and remove fan trays:

·     The switch is provided with the fan tray slots empty. Before powering on the switch, make sure all fan tray slots have fan trays installed and the fan trays are the same model.

·     Make sure all slots have a module or filler panel installed when the switch is operating.

·     If multiple fan trays fail on an operating switch, do not remove the fan trays at the same time. Replace the fan trays one after another and finish replacing each fan tray within 3 minutes.

 

The installation and removal procedures are the same for the LSWM1FANSA, LSWM1FANSAB, and FAN-40F-1-A fan trays. The following installation and removal procedures use the LSWM1FANSA fan tray as an example.

You can use the emulator program to connect a network device, a Telnet site, or an SSH site. For more information about the terminal emulator programs, see the user guides for these programs

Configure the terminal parameters as follows:

·     Bits per second—9600.

·     Data bits—8.

·     Stop bits—1.

·     Parity—None.

·     Flow control—None.

Powering on the switch

1.     Before powering on the switch, verify that the following conditions are met:

¡     All the fan tray slots have a fan tray installed.

¡     The power cords are connected correctly.

¡     The input power voltage is as required by the switch.

¡     The console cable is connected correctly.

¡     The configuration terminal (a PC, for example) has started, and its serial port settings are consistent with the console port settings on the switch.

2.     Power on the switch.

During the startup process, you can access BootWare menus to perform tasks such as software upgrade and file management. The BootWare interface and menu options vary by software version. For more information about BootWare menu options, see the software-matching release notes for the device.

3.     After the startup completes, you can access the CLI to configure the switch.
