Cisco Catalyst 2960-X Configuration Guide

After the switch detects a powered device, the switch determines the device power requirements and then
grants or denies power to the device. The switch can also sense the real-time power consumption of the device
by monitoring and policing the power usage.
Using the Switch USB Ports
The switch has three USB ports on the front panel — a USB mini-Type B console port and two USB Type
A ports.
USB Mini-Type B Console Port
The switch has the following console ports available on its front panel:
•
USB mini-Type B console connection
•
RJ-45 console port
Console output appears on devices connected to both ports, but console input is active on only one port at a
time. By default, the USB connector takes precedence over the RJ-45 connector.
Windows PCs require a driver for the USB port. See the hardware installation guide for driver installation
instructions.
Note
Use the supplied USB Type A-to-USB mini-Type B cable to connect a PC or other device to the switch. The
connected device must include a terminal emulation application. When the switch detects a valid USB
connection to a powered-on device that supports host functionality (such as a PC), input from the RJ-45
console is immediately disabled, and input from the USB console is enabled. Removing the USB connection
immediately reenables input from the RJ-45 console connection. An LED on the switch shows which console
connection is in use.
Console Port Change Logs
At software startup, a log shows whether the USB or the RJ-45 console is active. Each switch in a stack issues
this log. Every switch always first displays the RJ-45 media type.
In the sample output, switch 1 has a connected USB console cable. Because the bootloader did not change to
the USB console, the first log from switch 1 shows the RJ-45 console. A short time later, the console changes
and the USB console log appears. Switch 2 and switch 3 have connected RJ-45 console cables.
