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:

This connector (labeled 

) is used to receive the uplink optical signals from 

an Expansion Hub.

This connector (labeled 

) is used to transmit the downlink optical sig-

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.

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-9 female connector. Refer to Appendix A.6 on page A-9 for the cable pin-
out 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.

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-8 for the cable pinout.

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-
Browser.
