How the FDK and UDK Process Works

The 3Com Firmware Distribution Kit (FDK) makes system upgrades fast and easy for all 3Com products that are equipped with Flash PROMs. The first time you update the software requires that you purchase both the FDK and the product UDK. All subsequent updates require that you purchase only the new version of the UDK; you can re-use your original FDK.

When 3Com issues a software upgrade, we send the upgrade on diskette (UDK) to all registered users who order the upgrade or to all customers who have signed up for the Software Subscription Service (SSS). SSS is explained in more detail in the Preface of this manual. The upgrade takes only two or three minutes using an inband download or ten to fifteen minutes for an out-of-band download, after which time the EMM will be up and running the new version of software.
