Network Creation Failures
The following chapter describes potential issues which could arise when creating a new
network and offers solutions for each scenario.
5.3.1 Isolated Network Unit
When a single network unit is powered-up too late it may not be part of the network.
This can be identified if the LED does not turn green.
This situation is the same as when a new network unit is added to an existing network.
This is described in “Extending the network”.
5.3.2 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 they have
connections to other network units showing a green LED (see “LED indications”).

Should preferably not happen since you want the
network unit to be connected.

All’s fine. Should be the normal situation.
One way of checking this is to connect a PC with 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.
Turn-on a network unit.
2.
Wait until the orange LED turns off.
3.
LED turns green, the network unit belongs to the network.
4.
Go to the next network unit.
When a network unit is not connected, the orange LED is continuously on. When this
occurs the network unit must be reset to factory defaults (see “Reset to factory
defaults”) and then added to the network by power-cycling one of the other network
units (see “Extending the network”).
