en convenient, use AdminBrowser to perform System Test in order
to optimize
performance.
CAUTION! During System Test, the entire system is temporarily off-line and no RF is being transmitted. For
a fully loaded system (one Main Hub, four Expansion Hubs, and 32 RAUs), it can take up to 90
seconds to complete the test.
7 Check the Expansion Hub LEDs.
The LEDs should blink through
all states on power up.
If the LEDs do not blink on power up, replace the Expansion Hub.
If the LEDs do not illuminate at all, make sure the AC power cab
le is connected.
The UL status and DL STATUS LEDs should be green.
The e-HUB status and power LEDs should be green.
For each CATV port that has a connected RAU,
the LEDs should be green.
It can take several seconds for each CATV connection before the LE
Ds to display properly.
NOTE: Refer to “Troubleshooting Using LEDs” on page 185 for troubleshooting using the LEDs.
