Fusion Installation Procedures
Troubleshooting Expansion Hub LEDs During Installation
• All Expansion Hub PORT LEDs with RAUs connected should indicate Green/Red.
This indicates that the RAU is powered on and communication has been estab-
lished.
• The Expansion Hub
UL STATUS LED should be Green.
Table 7-6 Troubleshooting Expansion Hub LEDs During Installation
During
Installation LED State Action Impact
1. Expansion
Hub power
is On and no
RAUs are
connected
POWER
Off Check AC power; make sure the
Expansion Hub power-on switch
is on; replace the Expansion Hub.
The Expansion Hub is not
powering on.
PORT
LEDs are on but
didn’t blink through
all states.
Replace the Expansion Hub. The Microcontroller is not
resetting properly; flash
memory corrupted.
PORT
Flashing Red
(6 PPM)
Port unusable; replace the Expan-
sion Hub when possible.
Current sensor fault; do not
use the port.
UL STATUS
Red, after power-up
blink
Replace the Expansion Hub. The Expansion Hub laser is
not operational; no uplink
between the Expansion Hub
and Main Hub.
UL STATUS
Red
Check the Main Hub LEDs
Refer to page 7-24, item 2 in
Table 7-5.
Use AdminBrowser to determine
the problem.
No communication with
Main Hub.
DL STATUS
Red Check the downlink fiber for opti-
cal power; verify that the cables
are connected to correct ports
(that is, uplink/downlink)
Check the Main Hub LEDs. Refer
to page 7-24, item 2 in Table 7-5.
No downlink between the
Expansion Hub and Main
Hub.
2. Expansion
Hub power
is On and
RAUs are
connected
PORT
Off Check the CATV cable. Power is not getting to the
RAU.
PORT
Flashing Red
(60 PPM)
Test the CATV cable. If the cable
tests OK, try another port. If the
second port’s LEDs are Red/Off,
replace the RAU. If the second
RAU doesn’t work; replace the
Expansion Hub.
Power levels to RAU are not
correct; communications are
not established.
If the second port works, flag
the first port as unusable;
replace EH when possible.
PORT
Red Use AdminBrowser to determine
the problem.
RAU is off-line.
