Cisco Systems WSC2960X48TDL manual Using the Switch USB Ports, USB Mini-Type B Console Port

Configuring Interface Characteristics

Using the Switch USB Ports

•a Cisco pre-standard powered device (such as a Cisco IP Phone or a Cisco Aironet Access Point)

•an IEEE 802.3af-compliant powered device

•an IEEE 802.3at-compliant powered device

A powered device can receive redundant power when it is connected to a PoE switch port and to an AC power source. The device does not receive redundant power when it is only connected to the PoE port.

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.

Note Windows PCs require a driver for the USB port. See the hardware installation guide for driver installation instructions.

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.
