- 时间: 2012-10-28 06:51自己DIY了一条串口线,能够登陆到终端了,机器启动,看到信息流出来
最后到了登陆提示
Select access level (read, write, administer ):
默认密码,administer/空白, 试过不行
网上流传的,debug/sysnnet, 也不行
打入read,密码空白,倒是能显示很多东西,不过显示出来的都是乱码
我把主板上的电池拆出来一分多钟,又装回去,没起到清除记忆的作用
看过手册
3com corebuilder3500 command reference guide
3com coreBuilder 3500 Getting Started Guide
3com corebuilder3500 implementation guide
看到一条命令system nvdata reset,可以重新设置系统,可这个需要进入管理员权限,才能执行,现在问题是不知道管理员密码
都没有说明怎么重新设置管理员密码
那位大侠还有办法

-------------------------------------------
Connect your PC's serial port to the RS232 port on the 3CB9EME card using a Null Modem cable. Use ProComm or HyperTerm as your terminal emulator. Try port settings
of VT100, 9600, 8, N, 1 with NO hardware or software
flow control.
The EME module on the CB9000 works the same way as the CB5000 management module.
After the machine boots up and you are presented with the login prompt, do the following.... (case sensitive)
login : FORCE
password : FORCE
Then push the EME Reset button within the next 10 seconds.
As the CoreBuilder re-initializes, you should see a text message as follows:
NVRAM not initialized or corrupt. Restoring factory default.
You now should be able to use "admin" as login with a blank password.
Login: admin
Password: <press Enter>
Welcome to administer service on CoreBuilder-9000.
CB9000> ? (to see possible commands)
Possible completions:
logout
reset
set
show
NOTE: While experimenting, I think I was also able to force a reset back to factory defaults by holding the EME Reset button down for about 10 to 15 seconds without doing the FORCE/FORCE login. I got the same message:
NVRAM not initialized or corrupt. Restoring factory default.
and was able to login as "admin" with a blank password.
------------------------------------------
As for Corebuilder 5000
The default name is system(lowercase)no password
login: system
password: <enter>
--------------------------------------
You forget the password for the "admin" user account and can no longer perform important management operations. Use the password recovery method outlined below to define a new password for the "admin" user account:
Access the Command Line Interface from the console port and enter the user name "recover" and password "recover" to place the Switch in password recovery mode. The Switch remains in password recovery mode for a maximum of 30 seconds, before it returns to the CLI login prompt.
You must use the console port to recover the passsword. If you attempt the recovery method using the network, the password will be rejected.
Perform a hard reset on the Switch whilst it is in password recovery mode by switching it off, waiting a few seconds, and switching it on again.
You cannot use a soft reset operation to reset the password of the "admin" user account. This will end the password recovery procedure and return you to the CLI login prompt.
When the Switch has rebooted following the hard reset enter a new password for the "admin" user account. -

you can go into Monitor more and delete the passwords. Found some better info on 3Com's site. Man, what a maze their site is.

这个Login : FORCE没用
返回:“FORCE” is not a valid access level

要在启动 CLI 前按某个键， 只有 30 秒。
CISCO 也是类似的，
XP 及以后的 WINDOWS 这个（组合）键 / 中断有问题。 发不出去。
所以进不了 RECOVER MODE。
也许这是个关键。 -

我看到的手册,没有提到过recover这个名字
