Key Considerations 775
The phone cannot be reached
If the phone should be on the network but is unconnected, this means that none of the network nodes on the network (routers, switches, or hubs) saw the physical address (the MAC address) of the phone. This in turn means that the phone is unreachable, possibly due to being disconnected, or having a broken link. To check this:
1Make sure that the phones can be reached.
2Check that the phones are correctly connected and the links are up.

The phones should now be connected on the 3Com Network Director map.
The network device the phone is connected to has not been discovered
If the network device that the phone is connected to has not been discovered by 3Com Network Director then it will not be possible to connect the phone to the rest of the topology. If this is the case then you may resolve this by taking the following steps:
1Determine the IP address of the network device that the phone is connected to.
2Launch the Network Discovery wizard using the Tools > Network Discovery menu option.
3In the Discovery Type stage, select Specify subnets and click Next.
4In the Specify Subnets stage, add the subnets that contains the network device that the phone is connected to, restricting the ranges to just the IP address of the network device if desired.
5Complete the network discovery.
After the network device has been discovered it should be added to the map and the phone connected to it.
Why are some phones on the map showing the user name, while others show the extension number?
By default, the label for a phone is the phone user name, in the format first name and last name. However, in some cases the phone user name is not set and shows the default values: New for the first name and User for the last name.
