Multiple networks created
When more than one network unit is powered-up too late, these network
units could form their own network.
Initially this will not be clear because all network units will indicate that
connections to other network units have been established with a green
LED (see “LED displays [ → 11]”).
One way of checking this is to connect a PC with a fixed IP address to
each network unit and try to ping the PCs from another PC. Another way
is to switch-off all but one network unit. Then complete the following steps
for each additional network unit:
1. Switch a network unit on.
2. Wait until the orange LED goes out.
3. The LED lights up green and the network unit belongs to the network.
4. Go to the next network unit.
If a network unit is not connected, the orange LED lights up constantly.
When this occurs the network unit must be reset to factory defaults (see
“Resetting to factory defaults [ → 22]”) and then added to the network by
switching one of the other network units off and back on again (see
“Extending the network [ → 20]”).

Extending the network
Additional new network units can be added to an existing network. This
section explains how this is done.
6.4.1
Adding a new network unit
New network units can be added to an existing network. However, to
prevent any network unit from becoming part of the network, the user
must complete four simple but specific steps:
1. Place the new network units next to a network unit belonging to the
network.
2. Switch-on the new network units.
3. Within one minute, switch the existing network unit off and then back
on again.
4. After one minute the new network units will become part of the
network.
