1.2. Cable Connections

3Com recommends that you power off the router before connecting any cable.
Do not connect and disconnect synchronous or asynchronous serial WAN cables, console
cables, Ethernet cables, ISDN BRI cables, and 4-port serial WAN adapters while power to the
router is on. Connnecting cables while power to the router is on can crash the router or
damage the serial port.

1.3. Online Resources

3Com routers contain a software agent that can be upgraded using the command line
interface. The software agent that is initially provided with the routers does not fully support
GRE, L2TP, IPSec, or SNMPv3.
To download a software agent that adds full support for these features, visit the 3Com support
website at http://support.3com.com
contains encryption capabilities that are restricted to certain users and countries so approval for
these downloads can take up to 48 hours.
To upgrade to future software agents that contain additional features, you must purchase a
service contract. Details are provided on the Service and Warranty pages of the 3Com support
website http://support.3com.com
