Cisco 1720 Blinking

[lsmyn]

Its been working fine, today, nothing... power it on, OK light blinks 8 times, stops blinks again 8 times, then just blinks continuosly.

No other lites on in back, Front just PWR on and OK blinking.

Get a console cable and directly connect to it so you can see what is wrong when it boots.

OK.... Heres what I get:

System Bootstrap, Version 12.0(3)T, RELEASE SOFTWARE (fc1)
Copyright (c) 1999 by cisco Systems, Inc.
C1700 platform with 32768 Kbytes of main memory
device does not contain a valid magic number
boot: cannot open "flash:"
boot: cannot determine first file name on device "flash:"

sounds like the ios image on hte flash is corrupt or missing, go into rommon mode and check the flash file.

Dir of the flash gives same exact error.

Not on site yet, but will try to re-seat the flash card, maybe will get lucky..

I am new to any Cisco programming, if the Image is corrupt, does that mean I have lost the router programming, or is there a way I can get it back ?

This router interfaces with Voice/Data T1, data=10 channels, voice = 14 channels.

If Ive lost that programming, how difficult for someone to walk me thru re-programming, assuming its not hardware.

if he ios is corrupt or been deleted from the flash card, then you will need to reload the ios back into flash, via tftp. before you go on sight make sure you have a relevant ios version for the router and the means to upload the ios from a pc/laptop using the cisco tftp server.

Just curious... could someone have (remotely) done something to make this happen?

Someone probably deleted the contents of the flash memory. It could have been done weeks or months ago and you didn't notice until it was powered down and restarted. The running-config resides on the volatile memory (RAM). That is why it is so important to do a 'copy running-config startup-config' command prior to powering down or restarting a device.
