replacement. 

Experienced engineers are available to manage your installation with

implementation services are offered to fill resource gaps and ensure the 
success of your networking projects. For more information on 3Com

Contact your authorized 3Com reseller or 3Com for additional product

appendix.

Access Software 
Downloads

You are entitled to bug fix / maintenance releases for the version of 
software that you initially purchased with your 3Com product. To obtain 
access to this software, you need to register your product and then use 
the Serial Number as your login. Restricted Software is available at:

http://eSupport.3Com.com

To obtain software releases that follow the software version that you 
originally purchased, 3Com recommends that you buy an Express or 
Guardian contract, a Software Upgrades contract, or an equivalent 
support contract from 3Com or your reseller. Support contracts that 
include software upgrades cover feature enhancements, incremental 
functionality, and bug fixes, but they do not include software that is 
released by 3Com as a separately ordered product. Separately orderable 
software releases and licenses are listed in the 3Com Price List and are 
available for purchase from your 3Com reseller.
