serial port so that it can be configured using a terminal emulation program.
Only certain models support this featue.
Note
• USB Port—The USB port connects the switch to a USB device so that you can save and restore the
configuration files, firmware images, and SYSLOG files through the connected USB device.
• RJ-45 Ethernet Ports—The RJ-45 Ethernet ports connect network devices, such as computers, printers,
and access points, to the switch.
• SFP+ Port (if present)—The small form-factor pluggable plus (SFP+) are connection points for modules
