Upon power-up, the LEDs blinks for five seconds as a visual check that they are
functioning. After the five-second test:
LED states during power on will vary, depending on whether Expansion Hubs are
connected. Refer to Table 7-5 for possible combinations.

Installation
Power On LED State Action Impact
1.
Main Hub
power is
On with no
Expansion
Hubs con-
nected.
POWER
Off Check AC power; check that the Main Hub power-on
switch is on; replace the Main Hub
The Main Hub is not
powering on.
POWER
Red Replace the Main Hub The power supply is
out-of-specification.
PORT
LEDs are on
but they
didn’t blink
through all
states
Replace the Main Hub. The micro controller is
not resetting properly;
flash memory cor-
rupted.
PORT
Red The port is unusable; replace the Main Hub when
possible.
Fiber sensor fault, do
not use the port.

Expansion
Hubs con-
nected and
powered
on.
PORT
Off • If the port LEDs do not illuminate, check the fiber
uplink for excessive optical loss.
• If Expansion Hub’s
DL STATUS
LED is red:
• Verify that the fiber is connected to the correct
port (that is, uplink/downlink)
• Swap the uplink and downlink cables.
• Connect the fiber pair to another port. If the sec-
ond port’s LEDs do not illuminate Green/Red,
replace the Main Hub.
• If the second port works, flag the first port as
unusable; replace the Main Hub when possible.
No uplink optical
power, the Expansion
Hub is not recognized
as being present.
No communication
with the Expansion
Hub.
PORT
Red (60 ppm) • If the Expansion Hub
DL STATUS
LED is red,
check the downlink fiber cable for excessive opti-
cal loss.
• Connect the fiber pair to another port. If the sec-
ond port’s LEDs do not illuminate Green/Red,
replace the Main Hub.
• If the second port works, flag the first port as
unusable; replace the Main Hub when possible.
No communication
with the Expansion
Hub.
PORT
Red The Expansion Hub or connected RAU reports a fault
Use AdminManager to determine the problem.
The Expansion Hub or
one or more RAUs are
off-line.
