5.7 Network Unit
The proper behavior of a network unit can be identified by its state. This chapter
describes the states that can be identified for a network unit. To provide feedback on the
proper operation of the network unit to the user, these states are also mapped onto LED
indications.
5.7.1 State Definitions
The following states can be identified for a network unit:
State Description
Booting The firmware is starting up the network unit.
Read network info Network information is read from persistent memory.
Network setup The network unit was not previously part of a network and is trying to
detect other network units to create a new network.
Network extension The network is created, but still new network units can be added to
extend the network.
Check connections Checking whether the network unit is still in range of (has a connection
to) one or more neighboring network units.
Disconnected Part of a network, but not in range of other network units.
Connected Connected to one or more network units.
Transmitting Relaying Ethernet packets from wireless to the LAN and vice versa.
Error Hardware fault.
5.7.2 State Transitions
The transitions between these states are given in the following figure:
