Powering on the Expansion Hub
1 Connect the AC or DC power as explained in “Making Power Connections” on page 120.
2 Turn on the power to the Expansion Hub an
d check that all the LED lamps are functioning
properly.
Upon power-up, the LEDs blink for five seconds as a
visual check that they are functioning.
After the five-second test:
The POWER and UL STATUS LEDs should be green.
If the uplink fiber is not connected, the UL S
TATUS LED turns red indicating that there is
no communication with the Main Hub.
The E-HUB STATUS and DL STATUS LEDs should be red.
All port LEDs should be off, as no
RAUs have been connected yet.
Connecting the Fiber Cables to the Expansion Hub
CAUTION! Observe all Fiber Port Safety Precautions listed in “Safety Precautions” on page 109.
Prepare the Fiber Cables
1 Confirm that their optical loss does not exceed 3 dB optical budget. RL is less than -60dB.
2 If fiber distribution panels are used, confirm that the total optical loss of fiber cablefrom the
Main
Hub through distribution panels and patch cords to the Expansion Hub—does not
exceed the optical budget.
3 Make sure the fiber cable’s
connectors are SC/APC (angle-polished). Using any other
connector type will result in degraded system performance and may damage the
equipment. (You can use an SC/APC pigtail if the fiber cable’s connectors are not SC/APC,
refer to “Splicing Fiber Optic Cable” on page 146, or replace the connectors.)
Connect the Fiber Cables
The fiber cable is labeled with either 1 or 2, or is color-coded. For proper connection between the
Main Hub ports and the Expansion Hub ports, refer to the numbering or color-coded connections
you recorded when installing the Main Hub(s).
If the Fiber Jumper Is Labeled with 1 or 2
1 Connect 2 to
DOWNLINK on the Expansion Hub.
The DL STATUS LED should turn green as soon as you connect the fibe
r. If it does not, there is
a downlink problem. Make sure you are connecting the correct cable to the port.
2 Connect 1 to
UPLINK on Expansion Hub.
The UL STATUS LED turns green on the first Main Hub communication. I
t may take up to 20
seconds to establish communication.
The Expansion Hub’s E-HUB STATUS LED
turns green when the Main Hub sends it the
frequency band command.
