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,

1 Connect2toDOWNLINKontheExpansionHub.
The
DL STATUSLEDshouldturngreenassoonasyouconnectthefiber.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
