Just wanted to post the final outcome.
The problem was the DRAM...I replaced all 4 32MB sticks and it came right up.
Used the -y option for xmodem at 115200 which cut the transfer time in half as opposed to using xmodem at 115200.
Thanks for the advice everyone,
Yes, I did a copy flash tftp right after I bought it.
It ran fine for a about a week then had the crash.
At that time there was no magic number message, i'm guessing it happened this time because I just replaced the flash and there was nothing on it...
After the xmodem transfer and failed...
Something else I can't understand...Where is the downloaded image stored before being loaded into flash?
It can't be transferred to flash during xmodem, since the flash is erased after the transfer completes.
So where is this 31 MB IOS image being stored before being loaded into flash?
thanks...
I replaced the flash and the same thing is happening... Does anyone have any suggestions?
rommon 1 > xmodem -c c3640-js-mz.124-19.bin
Do not start the sending program yet...
device does not contain a valid magic number
dir: cannot open device "flash:"
WARNING: All existing data in flash will...
It has two 16mb as well, which I beleive is the max.
The size of the IOS is 31.4 MB
At the 9600 speed xmodem takes about 10 hours...
So the general consensus is that the two SDRAM sticks need to be replaced?
This is causing the checksum errors?
I'm a little green so I'm hoping someone here would be so kind as to throw me a lifeline.
I have a 3640 as part of my lab which had no problems for the first week or so.
One morning I came in and powered everything up and found the 3640 sitting in rommon.
Error : uncompressed image checksum...
Thanks, I've read Wendell Odom's blog posts and just couldn't find anything on the IOS for the switch and if it was important or not.
From what I've gathered the IOS isn't really the issue, just the model for command structure and features.
Hi all,
After reseaching quite a bit, I've decided to go the 2950 route, but was wondering if it makes a huge difference which IOS is loaded.
I have 3 routers all with 12.4
If the 2950 (not the 2950T) has 12.1, is that a big issue in terms of similarities on the exams, or is the main issue...
I figured it out...it's cheezy, but it works...
filetoclip text "C:\...abc.txt" - copy the file to windows clipboard
fopen 0 "C:\...abc.txt" create text - writes over the existing file
fputs 0 xyz - writes the string
fclose 0
cliptofile text "C:\..abc.txt" append - appends the original text...
How would I fputs my text on the top line of a text file each time, shifting the previous lines down?
When I append a text file using fputs or fwrite, I want the next line appended on the top line, not the bottom.
In other words, each successive string added to the text file is added to the...
I've read through what posts I could find, and it seems to work for some although I can not get it to work.
Seems the mail logon has been an issue for some.
I checked the Outlook profile it just shows the name as
Scooter, Bubba Q.
I saw a post stating that's not the actual name to use so...
Thanks,
Getting away from the waituntil is where I'm stuck.
I need to keep the connection alive while waiting for a specific time to execute a script.
A cheezy way of doing it is to open another procomm session run a keep alive script with a while loop containing
pause 300
sendkeystr "^M"...
I'm using the waituntil "22:00:00" command to execute a script, but while waiting for that time I need to keep the connection alive by sending something every 5 minutes or so.
I've used the while loop to keep it alive, but how do I execute the waituntil at the same time?
How do I keep the...
'modeless'...this is really all I needed and should have found this on my own, but I was nukin' it out.
There's other things I can use this for later, but for accessing the scrollback buffer it's not really necessary.
Just being able to work around the dialog without closing it is really all...
Here is the the type of dialog used.
I would like another control to access the scrollback buffer and another control to page up to review data without closing the script.
I have not found any terminal commands to access the buffer so I keep thinking that ALT-E-C from the terminal menu is the...
it is a regular dialog box created in my script
basically I want a control to ALT-E C to access the scrollback buffer and scroll up without closing the dialog box.
I need to send and ALT key combination while my dialog box is open.
I can "transmit" text and caret translations while my dialog box is open but sendkey, sendvkey sends the vkey to the dialog window and not transmit out the terminal.
how do I transmit an ALT key without destroying my dialog?
