High-Speed Stack Connections
Theswitchhasrear‐panelconnectorsforhigh‐speedconnectionsinastackconfiguration.
Thehigh‐speedstackingcablesusedfortheconnectionsareoptionalitemsandmustbe
orderedseparately.Therearetwotypesofcables:
•C2CAB‐SHORTcablestoconnecttwoadjacentswitchesinthestack,and
•C2CAB‐LONG
cabletoconnectfromthetopswitchtothebottomswitchinthestack.
ThiscablecanalsobeusedinplaceoftheC2CAB‐SHORTcabletoconnectswitches
thataretoofarapartduetothephysicalarrangementoftheswitchesinthestack.
Redundant Power Supply Capability
Theswitchhasredundantpowersupplycapabilitywhenconnectedtoanoptional
externalredundantpowersupply(RPS).Iftheinternalpowersupplyfails,theRPS
assumestheentireloadoftheswitchwithoutinterruptingnetworktraffic.Theinternal
powersupplyandRPSeachhavetheirownACpowerconnection,whichenables
the
connectionofeachpowersupplytoadifferentACpowercircuitforadditionalACpower
sourceredundancy.
Connectivity
YoucanconnectthisswitchtoGigabitEthernetnetworksorworkstationsbywayof
optionalMini‐GBICsinstalledinthe24SFPportslotsfor1000BASE‐SX/‐EX/‐ELX
fiber‐opticconnectionsand1000BASE‐Tcopperconnections.
Atthetimeofthisprinting,theMini‐GBICssupportedandavailablefromEnterasys
are
describedinTable 1‐1onpage 1‐3.TheseMini‐GBICsmeetorexceedtheIEEE802.3z‐1998
