download procedure.
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.
