What is a .bin file I have the sdm cd but can't find the .bin file...

<div>
The .bin file is the actual IOS image for the router. &nbsp;Do you have any documentation of what version you were running?

Those files are for loading the SDM (security device manager). &nbsp;Do you have any other media that might have the actual IOS .bin file? &nbsp;If you have a current SmartNet contract, you can download IOS images from cisco's website.

cannot determine first file name on device &quot;flash:&quot; cisco 837

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.
