877: Problems after installing Strata Flash
Recently installed a 16MB strata flash module into the 877. After installing, everything appears to be ok but no connection can be made. All the LED lights are on including the FE0 ( connection to my laptop ). Even trying to use the default ip address ( 10.10.10.x) and the network ( 192.168.x.x ) still results in nothing. Am I missing a step after installing the flash? Thought I could just pop it in and go.
Boy, are you in for a big adventure...especially if you didn't back up the contents of your flash: directory before you started.
87x series routers come configured with either 24MB or 28MB flash RAM. The gotcha is that 20MB of that flash RAM is on the mainboard with either a 4MB or 8MB StrataFlash card, but the router sees these two areas of flash RAM as one contiguous area.
Once you replace that 4MB or 8MB StrataFlash card and replace it with another card the flash: area is invalidated. You will have to telnet into the router to format the flash: area, copy your IOS image back to the router which you hopefully have backed up somewhere & then reinstall SDM (if you use it), and copy back over your config file (which you also hopefully backed up).
If you didn't back up any of these things you should be able to drop the old StrataFlash card back in & back things up if you haven't messed around with the router after you installed the new card.
I hope I didn't confuse you.
O crap . Dont suppose I can pop in the old flash back in.
One major problem though, how do I telnet in? Router isnt even responding to pings. I have a backup of the old IOS image so that isnt much of a problem. Also have an Adv. IP Services image on CD.

You are going to have to use the console cable to go in. That's the only way. It's not going to respond to pings as until an IOS is loaded the ethernet ports are not going to be functional/recognized by the router.
You will need to use something like HyperTerminal to connect via COM1 (or whichever serial port you connect the console cable in) & you will find the router sitting in ROMMON mode.
You will then have to format the flash: and then use either XModem or TFTP to transfer an IOS image from your PC to the router.
I do not know if you can pop the old flash back in, but it is certainly worth a try if there are files on there you need to get back.
I'm sure you are freaking out right now, but so long as you have an IOS image to install you're going to be okay. I was in the exact same shoes you were in when I expanded the flash RAM on my 871W. Watching all the scary error messages fly by in HyperTerminal is enough to make you pucker. All those memory bad error messages (evidently unformatted flash is the same as bad flash RAM as far as the error messages are concerned) go away though after you format the flash.
Oh, and typing HELP at the ROMMON> prompt will go a long way in showing you what you have to type to get the flash formatted and an IOS image loaded onto the router. Just stay calm through the process & you'll be okay.
Well not freaking out really, just groaning. Wonder how long this is going to take me. But thanks a mil for the help.
