Baud Reset Button; Interface Numbering - Cisco WS-C1924-A - Catalyst 1900 24 Ports 10MB Switch Hardware Installation Manual

Chapter 1 Overview of the Router
The wireless access point does not have an external console port for connections. To configure the
wireless device, you must use a console cable to connect a PC to the host router's console port as
described in
use the Cisco IOS command-line interface (CLI) to access the interface.

The 5-GHz radio incorporates an Unlicensed National Information Infrastructure (UNII) radio
transceiver operating in the UNII 1, 2, 3, 5-GHz frequency bands.

Baud Reset Button

The Cisco 1905 and Cisco 1921 ISRs have a baud reset button on the back panel. When the button is
pressed during power on, ROMMON resets the router to the default console port configuration. If the
baud reset button is pressed for longer than 30 seconds, the router defaults to the read-only ROMMON
image. The default console port configuration is 9600 baud, 8 data bits, 1 stop bit, no parity, and flow
control is set to none.

Interface Numbering

Each individual interface (port) on a Cisco 1900 series router is identified by a number. The Cisco 1900
series routers contains the following wide-area network (WAN) and local-area network (LAN) interface
types:
•
•
The numbering format for the slots is interface-type 0/slot-number/interface-number.
