Uplink/Downlink Optical-Fiber Ports
The uplink/downlink optical-fiber ports transmit and receive optical signals between the Main
Hub and up to four Expansion Hubs using industry-standard SMF or MMF cable. There are four
fiber ports on the front panel of the Main Hub—one port per Expansion Hub. Each optical-fiber
port has two female SC/APC connectors:
UPLINK Co
nnector—receives the uplink optical signals from an Expansion Hub.
DOWNLINK Connector—transmits the dow
nlink optical signals to an Expansion Hub.
CAUTION! To avoid damaging the Main Hub’s fiber connector ports, use only SC/APC fiber cable connectors
when using either single-mode or multi-mode fiber. Additionally, it is critical to system
performance that only SC/APC fiber connectors are used throughout the fiber network, including
fiber distribution panels.
Main Hub LED Indicators
The unit’s front panel LEDs indicate faults and commanded or fault lockouts. The LEDs do not
indicate warnings or whether the system test has been performed. Use the LEDs to provide basic
information only, or as a backup when you are not using AdminBrowser.
Upon power up, the Main Hub goes through a 20-second test to check the
LED lamps. During this
time, the LEDs blink through the states shown in Table 31 on page 34, letting you visually verify
t
hat the LED lamps and the firmware are functioning properly. Upon
completion of initialization,
the LEDs stay in one of the first two states shown in Table 31 on page 34.
The Main Hub automatically sends the
program
bands command to all connected RAUs. A
mismatched band causes a fault message to be displayed in AdminBrowser and places the RAU in
a disabled condition.
NOTE: Refer to Troubleshooting Using LEDs” on page 185 for troubleshooting using the LEDs.
NOTE: AdminBrowser should be used for troubleshooting the system. Only use LEDs for backup or
confirmation. However, if there are communication problems within the system, the LEDs may
provide additional information that is not available using AdminBrowser.
