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Connect
or—Thisconnector(labeledUPlink)isusedtoreceivethe
uplinkopticalsignalsfromanExpansionHub.
• OpticalFiberDownlinkConnector—Thisco
nnector(labeledDOWNlink)isusedto
transmitthedownlink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.
CommunicationsRS‐232SerialConnector
• RemoteMonitoring—Useastandardserialcabletoconnectamodemtothe9‐pinD‐sub
maleserialconnectorforremotemonitoringorconfiguring.ThecabletypicallyhasaDB‐9
femaleandaDB‐9femaleconnector.Refer“DB‐9toDB‐9NullModemCable”onpage201to
forthecablepinoutdiagram.
Remotemonitoringisalsoavailablebyco
nnectingtheRJ‐45(ADMIN/LAN)porttoaLAN
switchforremoteEthernetLANaccessordirectdial‐uprouteraccess.
• LocalMoni
toring—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
“TCP/IPCross‐OverCable”onpage200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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3‐1,lettingyouvisuallyverifythat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3‐1.
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186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.
