Best practice ZigBee initial network
start-up procedure
Inordertoavoidcreatingorphandevices/nodes
/controllersandmovingaboutdevices/nodes/
controllers during the initial network start-up, it is
recommended that the same power up sequence initially
used for the survey be used.
Pleasenotethatonceadevice/node/controllerhas
been assigned a ZigBee address and has joined the
active ZigBee network, it will save it’s assigned ZigBee
address to ash memory and re-use it afterwards even
after a power failure or a network re-start. The ONLY time
device/node/controllerwouldrequireaNEWZigBee
address is if the network is re-started with either a new
PAN ID or a new Channel value. This causes the currently
assigned and saved ZigBee address in ash to be erased

7. Ifmorethan5devices/nodes/controllersare
present in the same area where readings were taken,
IT IS RECOMMENDED that another Jace coordinator
be used (fig. 15).
