Sun V880 串口登錄，能看到輸出，但無法輸入

jackiew

Hi all，

Sun V880 串口登錄，能看到輸出，最大化自檢沒有報錯，但到OK提示符后無法輸入，為什么？

謝謝！

hlzhan

type "." or "Break" couple times.

謝謝這么快回復�。海�

我試過敲入"." 或 "Break"很多次，但還是反應。：（

是不是和RSC有關？聽說用過RSC后就會這樣。如果是這樣的話，如何再恢復成默認的串口？在OK下輸入reset-all會不會奏效？

看一下你的輸入和輸出設備設得有沒有錯誤。

都沒有�。�

{6}OK

顯示到在這里想輸入命令時就無法輸入了。

我接上顯示器、鍵盤、鼠標后，輸入以下命令還是不行:
ok diag-console ttya
ok setenv input-device ttya
ok setenv output-device ttya
ok reset-all

jackiew

暈哦，這下好了，串口還是用不了，接上鍵、鼠、顯示器也什么都看不到了。

如何再復位成原來的狀態(tài)啊，現(xiàn)在是最大化自檢，按兩個Power Button卻關機了，那個鑰匙也找不到了。

ac220v

1. Press the power button to power up the system.

2. Once the maintenance LED starts to flash rapidly, immediately press the Power button twice (similar to double-clicking a mouse, but leave a short gap of around 1 second between presses, to have the action reliably registered.) The actual time when you do the double press of the power button is the point in POST when the maintenance LED (wrench light) rapidly flashes.

NOTE:

If you double press too late or too soon, the system will power off. Do not get confused with the earlier occurrences of the maintenance and OK to remove LEDs flashing together. This is a part of the system test to make sure the LEDs are functional.

If you're running POST even in MIN level, it will be several minutes depending upon your configuration, before the maintenance LED flashes rapidly.

ac220v

多試兩次  很有可能是你的串口線  或者終端設置問題  
如果不是  那可能是你的io板上的  ttya的rx部分有硬件故障。。。。。

謝謝各位回復！

我拔掉了RSC卡，再用串口連上去，自檢完成后還是在OK那里無法輸入，我現(xiàn)在再改成鍵鼠顯示器試試，如果不行就按ac220v的說法按兩次power button去reset試試看。
