Modifying the IP Address Settings
To enable devices on the network to communicate with
the Switch, you need to assign an IP address to it —
either by DHCP or by assigning a static IP address.
To enable devices on the network to communicate with
the Switch, the Switch will either obtain an IP address
from a DHCP server (default operation), or if this is not
successful, will allocate itself an IP address. You can use
the console interface or the 3Com Switch Detect
application (with certain limitations) to see what IP
address the Switch will use.
Automatic IP Configuration
When you power on the Switch for the first time, it will,
for a period of approximately 2 minutes, automatically
request an IP address from a DHCP server. This is
referred to as auto mode. If at the end of this period
there has been no response from the DHCP server (if
one is present in the network), it will allocate itself an
Auto IP address.
The Switch will use the default IP address 169.254.x.y,
where x and y are the last two bytes of its MAC address.
