Installation Requirements

Before You Begin Installation

Ensure you have the following:

• Phillips screwdriver.
• Standard-sized, 19" wide rack with a minimum of 1U height available.
• Category 5e or higher RJ-45 Ethernet cables for connecting network devices.

Site Environment

• Operate in an area not exceeding an ambient temperature of 45°C.
• Ensure the installation site is well-ventilated with adequate airflow around the switch.
• Verify the switch is level and stable to avoid hazardous conditions.
• Do not install in a dusty environment.
• The installation site must be free from leaking or dripping water, heavy dew, and humidity.
• Ensure rack and working platforms are well earthed.

Mounting the Switch

Attaching the Brackets

Attach front and rear-post brackets to the switch using M4 screws. Secure rear-post brackets at the mid-point on the sides with two M4 screws. Use screws and cage nuts supplied with the rack to secure the switch in the rack.

Adjusting Rear-Post Bracket Ears

First, adjust the position of rear-post bracket ears and secure them in the rack. Then, lock their position using the included ear-locking screw.

Grounding the Switch

Connect one end of the grounding cable to a proper earth ground, such as the rack. Secure the grounding lug to the grounding point on the switch back panel with washers and screws.

CAUTION: The earth connection must not be removed unless all supply connections have been disconnected.

Connecting the Power and Ports

Connecting the Power

Plug the AC power cord into the power port on the back of the switch and connect the other end to an AC power source.

WARNING: Do not install power cables while the power is on.

Connecting the SFP+ Ports

Plug the compatible SFP+ transceiver into the SFP+ port. Connect a fiber optic cable to the transceiver and then to another fiber device.

Connecting the QSFP+ Ports

Plug the compatible QSFP+ transceiver into the QSFP+ port. Connect a fiber optic cable to the transceiver and then to other fiber devices.

Connecting the SFP28 Ports

Plug the compatible SFP28 transceiver into the SFP28 port. Connect a fiber optic cable to the transceiver and then to other fiber devices.

Connecting the QSFP28 Ports

Plug the compatible QSFP28 transceiver into the QSFP28 port. Connect a fiber optic cable to the transceiver and then to other fiber devices.

WARNING: Laser beams can cause eye damage. Do not look into bores of optical modules or optical fiber without eye protection.

Connecting the Console Port

Insert the RJ45 connector of the console cable into the RJ45 console port on the front of the switch. Connect the other end of the console cable to the RS-232 serial port on the computer.

Connecting the MGMT Port

Connect one end of a standard RJ45 Ethernet cable to a computer. Connect the other end of the cable to the MGMT port on the front of the switch.

Connecting the USB Port

Insert a USB flash disk into the USB port.

Configuring the Switch (Only for Cumulus Linux Switch)

Installing Cumulus® Linux® License Over Switches

Install Cumulus Linux License Key

There are three ways to install the license onto the switch:

• Copy and paste the license key into the `cl-license` command: cumulus@switch:~$ sudo cl-license -i <paste license key> followed by `^+d`.
• Copy the license from a local server. Create a text file with the license and copy it to a server accessible from the switch. Use the command: cumulus@switch:~$ scp user@my_server:/home/user/my_license_file.txt . then cumulus@switch:~$ sudo cl-license -i my_license_file.txt.
• Copy the file to an HTTP server (not HTTPS) and reference the URL when running `cl-license`: cumulus@switch:~$ sudo cl-license -i <URL>.

CAUTION: It is not necessary to reboot the switch to activate the switch ports. After you install the license, restart the `switchd` service. All front panel ports become active and show up as swp1, swp2, and so on.

cumulus@switch:~$ sudo systemctl restart switchd.service

Set up Configuration Environment via Console Port

1. Connect the serial port of a PC (or a terminal) to the console port of the switch with the console cable.
2. Turn on PuTTY. Choose “Serial” as the Protocol.
3. In the Port item, choose the specified COM port that the PC is using.
4. Set the baud rate to 115200, data bit to 8, parity check to none, stop bit to 1, flow control to none.
5. Enter the default login information: Username: cumulus, Password: CumulusLinux!
6. Use the corresponding commands to configure the switch or to monitor the running state.

Troubleshooting

Power System Troubleshooting

According to the power indicator on the front panel, you can determine if the power system is faulty. If the power supply system is working normally, the power indicator should remain lit. If the power indicator is unlit, the power supply system is not working. Please check the following:

• Whether the switch power cable is connected correctly.
• Whether the power supply of the switch matches the required power supply.

Configuration System Troubleshooting

After the switch is powered on, if the system is normal, the startup information will be displayed on the configuration terminal. If there is something wrong with the configuration system, the configuration terminal may not display or may display error codes.

Troubleshooting for Terminal No-show

After power-on, if the configuration terminal shows nothing, you can first check the following:

• Whether the power supply is normal.
• Whether the console cable is properly connected.

If there is no problem with the above, it is very likely that there is a problem with the configuration cable or the terminal (such as the HyperTerminal) parameters were set incorrectly.

Troubleshooting for Terminal Show Error Codes

If the configuration terminal shows error codes, it is likely that the terminal (such as the HyperTerminal) parameters were set incorrectly. Please confirm the parameters of the terminal.
