# Cisco reset : 以 3750G 為例
### [設定]:
1. 接上 Console 線啦,COM1 or COM2 看你自己的機器囉...
```
Terminal 設定如下:
9600 baud rate, No parity, 8 data bits, 1 stop bit, No flow control
```
2. 拔掉電源線,並長按 "**mode**" button, 然後開機.
3. Type **flash_init**
4. Type **load_helper**
5. Type **dir flash:**
#### 要確定 dir flash 後面有加 ":"
接下來應該會看到像下面的:
```
Directory of flash:
2 -rwx 843947 Mar 01 1993 00:02:18 C2900XL-h-mz-112.8-SA
4 drwx 3776 Mar 01 1993 01:23:24 html
66 -rwx 130 Jan 01 1970 00:01:19 env_vars
68 -rwx 1296 Mar 01 1993 06:55:51 config.text
1728000 bytes total (456704 bytes free)
```
6. Type rename flash:config.text flash:config.old
將原來的 configuration file改名,如果接下來要乾淨的重新設定這台 switch 的話,那就直接把檔案殺了就好。
7. Type boot to boot the system.
8. Enter N at the prompt to start the Setup program, Continue with the configuration dialog? [yes/no] : N
9. At the switch prompt type en 進入特權模式( enable mode).
10. Type rename flash:config.old flash:config.text 將 configuration file 改回原始檔名. (如果還需要保留舊的設定時才需這個動作)
11. Copy the configuration file into memory:
```
Switch# copy flash:config.text system:running-config
Source filename [config.text]? (press Return)
Destination filename [running-config]? (press Return)
The configuration file is now reloaded.
```
12. 接下來就是重頭戲了,改密碼:
```
switch#configure terminal
switch(config)#enable secret ooxx123 (其中 ooxx123 就是密碼啦,改成你要的)
!-- This step is necessary if the switch had an enable secret password
switch#(config)#^Z
!--Control/Z
```
13. Write the running configuration to the configuration file:
```
switch#write memory
```
接下來就是做其他的基本設定 設備名稱、建立其他使用者、vlan、ssh、介面 ip
開啟 ssh
設定介面 一個對外 ip
