Hi,all
Last Friday,I go out to solve a cat6k's boot problem,Its a Cat6K with
6006 chassis,supervisor 1a msfc2 and one ws-x6408 line card,the
boot problem is:after it decompress the image and displays four lines of
diag message ,the system is halted at "boot bootflash:cat6000-xxx.bin",at
that time, the led is stats:green and left are all orange.I have check the
bootvar and in rommon use "boot bootflash:cat6000xxx.bin",both useless.so i
begin to doubt the problem is caused by the image file,is
cat6000-6.1.2.bin,I got a 5.5.10 image that is the cisco recommended.I begin
to download this
image to supervisor using xmodem,after about 2hours,really a long time
wait,the download complete and begin to decompress the image,only
a few lines it report an error.I don't want to wait for a so long time
again and deside the do the upgrade as router 3600:change the console speed
using conreg ,but the cat6k's confreg command only has 1200,2400,4800 and
9600bps options,I deside to try the 115,200bps,
in 3600 the register is 0x3922.so I configure it in Cat6K.
Then I cannot enter the console,only meanness characters .The time is up,I
back to Company and check the doc ,I found that 0x3922 in cat6k
means baud rate 4800 and "the break is disabled".I also see in somewhere
that it says the break is always enabled in the first 60 sec
and whenever the break is set disabled",Can I still can enter the console??
next Monday I will go and check.Anybody who can give some advise ,Thanks.
