Table 4 SCRN-530 LED Boot Sequence
State
LED Color
Description
Possible Failures and
Actions
0. Power On/
Reset
Flashing
Green
This is the initial state on
startup. The radio node
bootup is controlled by
firmware in this state.
This state should be very short
lived and should transition to
the next state immediately.
1. Software
Initialization
Flashing
Green
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.
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.
2. DHCP
Solid Red
The radio node starts by
sending out a DHCP Request.
The radio node moves to the
next state (State 3) upon
receiving a DHCP response
and an IP Address.
No DHCP Response, IP Address
not allocated.
Check cabling, DHCP Server
configuration.
3. Join
Solid Blue 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.
No IP reachability to the
centralized unit.
Check IP network between
radio node and centralized
unit for routing issues.
