The Switch 4400 and Switch 4400 SE can only be stacked together if the
Switch 4400 SE has been upgraded using the Switch 4400 SE Enhanced
Software Upgrade (3C17207). This ensures that both Switches support
the same features across a stack.
Once a Switch 4400 SE has been upgraded with the Enhanced Software
Upgrade (3C17207), it can be stacked with Switch 4400 units, but not
with Switch 4400 SE units that have not been upgraded.
For further
information about stacking, refer to Chapter 2 of the Getting Started
Guide that accompanies your Switch.
To upgrade the Switch 4400 SE:
1 Purchase the Switch 4400 SE Enhanced Software Upgrade (3C17207)
from a 3Com distributor. This is supplied with an encrypted License Key
that you must register on the 3Com Web site.
2 Visit the following URL on the 3Com Web site:

5 Enter the Serial Number of your SuperStack 3 Switch 4400 SE unit. The
Serial Number can be found on the underside of the unit.
6 Enter the License Key of the Enhanced Software Upgrade. The License
Key is supplied on the cover of the Switch 4400 SE Enhanced Software
Upgrade CD.
7 Enter your email address. 3Com uses this address to confirm the details
of your Upgrade License.
8 Select Submit .
If you have not already done so, you must now register your SuperStack 3
Switch 4400 SE unit. Your Switch 4400 SE unit must be registered before
you can use the Enhanced Software Upgrade.
An Activation Key for the Upgrade License is displayed, along with the
unit and License details. Make a note of the Activation Key (this is also
sent to the email address you entered in
step 7 above).
