FH1 2
Indicates the status of the
Ethernet fronthaul data
Port 1 throughput
• OFF when no power is applied to the unit or
when booting
• Steady GREEN when port has link and
operating at Gigabit Ethernet rate, but there is
no Ethernet activity
• Slow GREEN when port is operating at Gigabit
Ethernet rate and has Ethernet activity
• Steady AMBER when less than Gigabit
Ethernet mode
• RED when a critical fault occurs

Indicator state Description Operation
Steady OFF LED OFF Not operational
Steady ON
LED is continuously
ON, on interruption
System or component is operational (i.e., delivering
service)
Slow blink
LED ON for about 0.5
s and OFF for about
0.5 s
On-going activity (i.e., system is booting, transition from
one mode to another, etc.)
Fast blink
Varying blink rate,
noticeably faster than
a slow blink rate
