If your IP network is internal to your organization only, that is, you do not
access the Internet, you may use any arbitrary IP address as long as it is not
being used by another device on your network. 3Com suggests you use
addresses in the range 192.168.0.0 to 192.168.255.255 with a subnet
mask of 255.255.255.0.
These suggested IP addresses are part of a group of IP addresses that have
been set aside specially for use 'in house' only.
If you are having problems with correctly forming a fabric, first ensure that
Spanning Tree is enabled. If it is enabled, do the following:
1 Power off all units in the fabric.
2 Check all the cable connections in the fabric.
3 Check the ports have been enabled as fabric ports.
4 Power on all units in the fabric.
