The flashable files on the download server are organized by product prefix. Depending on the product for which it is intended, the file name may designate the firmware number (verify that the correct firmware number is known – see Step 1. Identify the reflashable product); revision letter, if applicable, and firmware version number (V.X.X.X).

The current version firmware release is provided. If applicable, one version prior to the current release is also available. Be sure to identify and download the desired version.

The downloadable files are stored in two formats: *.exe (self-extracting) and *.zip (compressed). Some firewalls will not allow the downloading of *.exe files. In this case, download the *.zip file instead.

For additional help with "zipped" file types, refer to PKZIP for Windows, WinZip, or ZipCentral help files. PKZIP for DOS is not supported due to file naming conventions.

4.Extract the files to the temporary folder on the PC, then verify the success of the file extraction and transfer via the dir command. Using the CDM-600/600L firmware download archive for the CRS-300 as an example, at least four files should be extracted:

•CCCflash.hlp: CEFD Flash Upload Utility Program Help File.

•CCCFlash.exe or Cccflshc.exe: CEFD Flash Upload Utility Program, designed to run under Windows 95/98/2000→ or Windows NT→.

•fw#####x.ccc, where "#" denotes the firmware number, and “x” denotes the revision letter.

•ReleaseNotes*.pdf, where the firmware number, its revision letter, and the firmware version are typically identified.

If these four files as identified are displayed, the user should be ready to perform the flash upgrade.

5.Connect an EIA-232 serial cable (details are shown in the cable details box on the Uploader screen, as well as in Appendix A. CABLE DRAWINGS) from the computer to the remote control port of the Switch.
