Optical Fiber Uplink/Downlink Ports

The optical fiber uplink/downlink 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 fiber port has two female SC/APC connectors:
• Optical Fiber Uplink Connector
This connector (labeled
an Expansion Hub.
• Optical Fiber Downlink Connector
This connector (labeled
nals 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, includ-
ing fiber distribution panels.

Communications RS-232 Serial Connector

Remote Monitoring
Use a standard serial cable to connect a modem to the 9-pin D-sub male serial con-
nector for remote monitoring or configuring. The cable typically has a DB-9 female
and a DB-25 male connector. Refer to Appendix A.6 on page A-11 for the cable
pinout diagram.
Remote monitoring is also available by connecting the RJ-45 (ADMIN/LAN) port to
a LAN switch for remote Ethernet LAN access or direct dial-up router access.
Local Monitoring
Use a crossover Ethernet cable (PN-4069-ADB) to connect a laptop or PC to the
RJ-45 female connector for local monitoring or configuring using the AdminBrowser
resident software. The cable typically has a RJ-45 male connector on both ends. Refer
to Appendix A.5 on page A-10 for the cable pinout.

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 Admin-
