- Console Ports
- The 1200 series has two external console ports, a Cisco RJ-45 serial port and a Type C USB serial port. Only one serial console
port can be active at a time. When a cable is plugged into the USB console port, the RJ-45 port becomes inactive. Conversely,
when the USB cable is removed from the USB port, the RJ-45 port becomes active. The console ports do not have any hardware
flow control. You can use the CLI to configure the chassis through either serial console port by using a terminal server or
a terminal emulation program on a computer.
-
RJ-45 (8P8C) port—Supports RS-232 signaling to an internal UART controller. The RJ-45 console port does not support a remote dial-in modem. You can use an adapter to convert the RJ45-to-DB9 connection if necessary.
-
Type C USB port—Lets you connect to a USB port on an external computer. You can plug and unplug the USB cable from the console port without affecting Windows HyperTerminal operations. We recommend shielded USB cables with properly terminated shields. The default setting is 9600 baud. Use this for the initial connection. Baud rates for the USB console port are 1200, 2400, 4800, 9600, 19200, 38400, 57600, and 115200 bps.
-
- External Flash Storage
- The chassis provides a USB Type A port that you can use to attach an external device. The USB port can provide output power
of 5 volts and up to a maximum of 1 A (5 W of USB power).
-
External USB drive (optional)—You can use the external USB Type A port to attach a data-storage device. The external USB drive identifier is disk1. When the chassis is powered on, a connected USB drive is mounted as disk1 and is available for you to use. Additionally, the file-system commands that are available to disk0 are also available to disk1, including copy, format, delete, mkdir, pwd, cd, and so on.
-
FAT-32 File System—The 1200 series only supports FAT-32-formatted file systems for the external USB drive. If you insert an external USB drive that is not in FAT-32 format, the system mounting process fails, and you receive an error message. You can enter the command format disk1: to format the partition to FAT-32 and mount the partition to disk1 again; however, data might be lost.
