·     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. Table1-1 describes the dust concentration limits in the equipment room.

Installing/removing expansion modules

CAUTION

CAUTION:

When you install or remove an expansion module, follow these guidelines:

·     Never touch the components on the expansion module surface with bare hands.

·     Do not use excessive force.

·     If you are not to install a new expansion module after removing the original one, install a filler panel in the slot to prevent dust and ensure good ventilation in the switch.

·     Do not install or remove an expansion module during startup of the switch. Hot swapping an expansion module when the switch is operating correctly.

 

The installation and removal procedures are the same for expansion modules. The following procedure uses an LSWM2FPGAB interface module as an example.

Installing an expansion module

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

2.     Use a Phillips screwdriver to loosen the screw on the filler panel and remove the filler panel. Keep the removed filler panel secure for future use.

NOTE:

The LSWM2FPGAB interface module adds 55 mm (2.17 in) to the chassis depth. An interface module of other models (including its handle) adds 75 mm (2.95 in) to the chassis depth.

 

Removing an expansion module

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

2.     Use a Phillips screwdriver to loosen the mounting screw on the expansion module.

3.     Pull the expansion module slowly out of the slot along the guide rails.

Verifying the installation

After you complete the installation, verify that:

·     There is enough space for heat dissipation around the switch, and the rack is stable.

·     The grounding cable is securely connected.

·     The correct power source is used.

·     The power cords are correctly connected.

·     All the interface cables are cabled indoors. If any cable is routed outdoors, verify that the socket strip with lightning protection and lightning arresters for network ports have been correctly connected.

 


3 Accessing the switch for the first time

Connecting the switch to a configuration terminal

You can connect the switch to a configuration terminal only by using the serial console port.

In Figure3-1, the switch is connected to a configuration terminal (PC as an example) from the serial console port.

Figure3-1 Connecting the switch to a configuration terminal

 

Connecting a DB9-to-RJ45 console cable

CAUTION

CAUTION:

Follow these guidelines when you connect a DB9-to-RJ45 console cable:

·     Identify the mark on the serial console port and make sure you are connecting to the correct port.

·     The serial ports on PCs do not support hot swapping. To connect a PC to an operating switch, first connect the PC end. To disconnect a PC from an operating switch, first disconnect the switch end.

 

A DB9-to-RJ45 serial console cable is an 8-core shielded cable, with a crimped RJ-45 connector at one end for connecting to the serial console port of the switch, and a DB-9 female connector at the other end for connecting to the serial port on a configuration terminal.

To connect the switch to a configuration terminal (for example, a PC) by using a DB9-to-RJ45 console cable:

1.     Plug the DB-9 female connector of the DB9-to-RJ45 console cable to the serial port on the PC.

2.     Connect the RJ-45 connector to the serial console port on the switch.

Connecting a USB-to-RJ45 console cable

IMPORTANT

IMPORTANT:

·     To use a USB-to-RJ45 console cable to connect the switch to a configuration terminal, first download and install the USB-to-RJ45 console driver on the configuration terminal and then connect the USB-to-RJ45 console cable to the configuration terminal.

·     If you have connected a USB-to-RJ45 console cable to the configuration terminal before installing the driver, remove and reconnect the USB-to-RJ45 console cable to the configuration terminal after driver installation.

 

The following installs the driver on a Windows operating system. To install the driver on other operating systems, see the installation guide in the driver compression package named by using the corresponding operating system.

To connect the switch to a configuration terminal by using a USB-to-RJ45 console cable:
