This document describes the password recovery procedure for the Cisco Catalyst Layer 2 fixed configuration switches 2900XL/3500XL, 2940, 2950/2955, 2960, and 2970 Series, as well as the Cisco Catalyst Layer 3 fixed configuration switches 3550, 3560, and 3750 Series.//这个文档描绘了为思科二层固定交换机2900XL/3500XL, 2940, 2950/2955, 2960, and 2970系列和三层固定 交换机3550, 3560, and 3750系列所作的密码恢复技术
There are no specific prerequisites for this document.//此文件没有具体的先决条件
Follow the password recovery procedure below.//根据下面的密码恢复步骤
Attach a terminal or PC with terminal emulation (for example, Hyper Terminal) to the console port of the switch.//附加终端或终端仿真（如电脑，超级终端）到控制台交换机端口。

For 2955 series switches on
The Catalyst 2955 series switches do not use an external mode button for password recovery. Instead the switch boot loader uses the break-key detection to stop the automatic boot sequence for the password recovery purposes. The break sequence is determined by the terminal application and operating system used. Hyperterm running on Windows 2000 uses Ctrl + Break. On a workstation running UNIX, Ctrl-C is the break key. For more information, refer to .
//该2955系列交换机不使用密码的恢复外部模式按钮。相反，开关启动加载器使用的突破的关键检测以停止的密码恢复目的的自动启动顺序。该序列被打破终端应用程式和作业系统决定使用。 HYPERTERM的Windows 2000上运行使用Ctrl +Break。在运行UNIX工作站，按Ctrl - C是突破的关键。欲了解更多信息，参考标准Break键序列组合的密码恢复过程中。
The example below uses Hyperterm to break into switch: mode on a 2955.
