7.4.2.1 Troubleshooting Expansion Hub LEDs During Installation
• All Expansion Hub LINK and E-HUB/RAU LEDs with RAUs connected should indi-
cate Green/Red. This indicates that the RAU is powered on and communication
has been established.
• 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.
LINK
LEDs are on but
didn’t blink through
all states.
Replace the Expansion Hub. The Microcontroller is not
resetting properly; flash
memory corrupted.
RAU
LINK
Red Port unusable; replace the Expan-
sion Hub when possible.
Current sensor fault; do not
use the port.
RAU
Off
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 from green after
90 second power-up
blink, the cable was
connected within 90
seconds of power up.
Check the Main Hub LEDs
Refer to page 7-16, item 2 in
Table 7-5.
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 7-16, 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
LINK
Off Check the Cat-5E/6 cable.
Check the Cat-5 Extender if one is
being used.
Power is not getting to the
RAU.
RAU
Off
LINK
Red Test the Cat-5E/6 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.
Check the Cat-5 Extender if one is
being used.
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.
RAU
Off
LINK
Green Use AdminManager to determine
the problem.
RAU is off-line.
