Cisco Systems C3850NM210G, WSC385024TS, C3850NM41G manual Management Ports, USB Mini-Type B Port

Chapter 1 Product Overview

Front Panel

Depending on the installed power supply modules, each port can deliver up to 60 W of Cisco UPOE. See Table 1-15 on page 1-19for the power supply matrix that defines the available PoE, PoE+, and Cisco UPOE power per port. The output of the PoE+ circuit has been evaluated as a Limited Power Source (LPS) per IEC 60950-1.

Note For information about power supply modules, PoE+ port connections, and PoE+ specifications, see the “Power Supply Modules” section on page 1-18, the “PoE+ and Cisco UPOE Port Connections” section on page 2-20, and Appendix B, “Connector and Cable Specifications.”

Management Ports

•Ethernet management port (see the “Ethernet Management Port” section on page 1-23)

•RJ-45 console port (EIA/TIA-232) (see the “RJ-45 Console Port” section on page 1-23)

•USB mini-Type B console port (5-pin connector)

You can connect the switch to a host such as a Windows workstation or a terminal server through the Ethernet management port, the RJ-45 console port, or the USB console port (USB mini-Type B port).

The USB console port connection uses a USB Type A to 5-pin mini-Type B cable. The USB console interface speeds are the same as the RJ-45 console interface speeds.

USB Mini-Type B Port

The switch provides a USB mini-Type B console connection on the front panel, and the RJ-45 console port on the switch rear panel. Console output is always active on both connectors, but console input is active on only one connector at a time, with the USB connector taking precedence over the RJ-45 connector.

Use a USB type-A-to-USB 5-pin mini-Type B cable to connect a PC or other device to the switch. The required USB cable is included in the optional accessory kit.

The connected device must include a terminal emulation application.

Windows PCs need a driver for the USB port. See the “Installing the Cisco Microsoft Windows USB Device Driver” section on page C-4for installation instructions.

When the switch detects a valid USB connection to a powered device, input from the RJ-45 console port is immediately disabled, and input from the USB console is enabled. Removing the USB connection immediately reenables input from the Ethernet connection. An LED on the switch front panel (see Figure 1-4) is green when the USB console connection is enabled.

The switch provides a configurable inactivity timeout that reactivates the RJ-45 console if no input activity has occurred on the USB console for a specified time period. After the USB console has been deactivated due to a timeout, you can restore its operation by disconnecting and reconnecting the USB cable. You can disable USB console operation by using Cisco IOS commands. See the switch software configuration guide for details.

Note The 4-pin mini-Type B connectors resemble 5-pin mini-Type B connectors. They are not compatible. Use only the 5-pin mini-Type B. See Figure 1-3.
