NE2572ORackSwitch(referredtoasNE2572Othroughoutthisdocument).
TheNE2572Ousesawire‐speed,non‐blockingswitchingfabricthatprovides
simultaneouswire‐speedtransportofmultiplepacketsatlowlatencyonallports.
Port Configuration
TheNE2572Ocontainsthefollowingethernetports:
Forty‐eight25GigabitEthernet(GbE)SmallFormPluggable28(SFP28)ports
Six100GbEQuadSmallFormPluggable28(QSFP28)ports,eachofwhichcan
optionallybeusedasfour10GbESPF+ports,orfour25GbESPF28ports,ortwo
50GbEQSPF28ports,orone40GbEQSPF+port
Transceiver Configuration
QSFP+portscanbepopulatedwithopticalQSFP+modulesorpassiveDirect‐Attach
Cables(DACs),
includingthosethatallowtheporttobeusedasfour25GbESFP+
ports.
Orientation, Airflow, and Redundancy
TheNE2572Ois1Uinheightandcanbemountedhorizontallyorvertically,
dependingonyourapplication.Mountingoptionsareavailableforavarietyofrack
systems.
Forsuperiorreliability,theNE2572Ousesredundant,hot‐swappowersupply
modulesandsixhot‐swapfanmodules.Moduleoptionsareavailablefor
rear‐to‐frontairflow.
Management
Youcanmanagetheswitchthroughthelocalconsoleport,orthrougharemote
