【求助】P520 碰到 0549 问题无法启动

tk515

看redbook 说是dump问题，要用串口线连接进去操作

但是我用串口线就后面的T1口，终端总是显示乱码。我的设置是
9600-8-N-1

请问是设置问题呢，还是必须用专用的串口线？

还有谁能给出这个问题比较详细一点的解决方法


万分感谢！！！

进不去，屏幕无反应，面板上的液晶屏显示0549，红皮书上说

This LED hang is not listed in the system Common Diagnostic Information books,
RS/6000 Diagnostics Information for Micro Channel Bus Systems, SA38-0532 or
RS/6000 and pSeries Diagnostics Informationfor Multiple Bus Systems,
SA38-0509. It occurs when the machine has a system dump to be copied off, but
because the graphics adapter has not been configured or cannot be configured
at this time, it cannot inform you via the panel.

解决方案

Recovery
Complete the following recovery steps:
1. Power off the machine.
2. Obtain an ASCII terminal or a laptop with a terminal emulator. Set the speed
of the screen to 9600 baud, 8 bit, no parity, and 1 stop bit. Set the screen to
emulate a vt100 terminal.
3. Connect the ASCII terminal to the S1 serial port on the machine using a
RS232 terminal cable.
4. Power on the machine.
5. You will eventually see a message on the screen informing you that a dump is
on the paging space. The system is prompting for a device to copy the system
dump information.
6. If you have a tape, copy it off and send it to your normal AIX support
personnel. If you do not have a tape drive on the machine, you will have to
discard this dump by continuing the boot process.
7. When you get the login prompt, use SMIT to configure another dump device
on your machine. See Chapter 4, “System dumps” on page 69 for more
information.


我照做，结果笔记本上的终端显示一串乱码

还有，加问一句，如果不保存这个dump信息对系统没影响吧？

dump用作“问题分析”，丢掉对系统没影响

遇到过因为串口线序不对而致乱码的事情，供参考！
