Table 4 Radio Node LED Boot Sequence
Description
This is the initial state on startup. The radio
node bootup is controlled by firmware in this
state.
The firmware has loaded and transferred
control to the bootloader. Additional
hardware initialization and validation are
performed during this state. This state
concludes with a lamp test, cycling through
all LED colors.
Request.
The radio node moves to the next state
(State 3) upon receiving a DHCP response
and an IP Address.
The radio node has an IP Address and sends a
UDP Join request to the Serving centralized
unit.
The radio node moves to the next state
(State 4) upon getting a JOIN GRANT from
the centralized unit.
The radio node proceeds next to download
the operating system image from the
centralized unit.
The radio node moves to the next state
(State 5) after the image has been
downloaded.
The radio node loads the operating system
and starts the default platform applications.
The radio node moves to the next state
(State 6) when it establishes connectivity
with the centralized unit.
The operating system is running. The radio
node continues the startup sequence, but is
now controlled by the centralized unit.

Possible Failures and Actions
This state should be very short lived
and should transition to the next state
immediately.
This state should be very short lived
and should transition to the next state
immediately.
A radio node should not stay in this
state indefinitely.
Note: Flashing Green is also used to
indicate a radio node that has been
administratively disabled. This can be
determined from the CLI.
No DHCP Response, IP Address not
allocated.
Check cabling, DHCP Server
configuration.
No IP reachability to the centralized
unit.
Check IP network between radio node
and centralized unit for routing issues.
Failure to download TFTP image.
Check firewall between radio node and
centralized unit.
Failure to start the operating system.
This normally points to a software/
build issue. Please contact Corning
support.
The operating system is up and running
on the radio node.
Any subsequent state transitions can
now be tracked from events and logs
on the centralized unit.
