A 1GE/10GE/25GE SFP28 optical port sends and receives service data at 1 Gbit/s, 10 Gbit/s, or 25 Gbit/s.

When a 25GE optical module is connected to a port, the port can automatically adjust its rate to 25 Gbit/s.

When a 10GE optical module is connected to a port, the port can automatically adjust its rate to 10 Gbit/s.

Before installing a GE optical module or GE copper module on a port, run the port mode ge command to configure the port to work at 1 Gbit/s.

Console cable

You can connect a switch to a configuration terminal or network management workstation through the ETH management port to configure the switch locally or remotely.

You can choose to download the software package through the ETH management port in the BootLoad menu. File transfer through the ETH management port is faster than transfer through the console port.

Ethernet cable

The USB port can have a USB flash drive connected to upgrade the switch, or transfer configuration files or other files. The USB port can only connect to a USB flash drive that complies with USB 2.0.

USB flash drives from different vendors differ in model compatibility and drivers. If a USB flash drive cannot be used, try to replace it with another one from a mainstream vendor. Switches support a maximum of 128 GB USB flash drives.
