With growing number of Power-over-Ethernet(PoE) powered edge devices, and the explosionof multi-media traffic and cloud-based apps onthe Local Area Network (LAN), having a resilientnetwork infrastructure is essential to yourbusiness. And a key to having a resilient networkis to ensure uninterrupted power.ADTRAN addresses this need with theNetVanta 1131 RPS/EPS unit, which providesredundant power and supplemental power tothe NetVanta 1600 Series, and redundant powerto the NetVanta 1500 Series Gigabit switches.HardwareThe NetVanta 1131 has three Redundant PowerSupply (RPS) outputs and one External PowerSupply (EPS) output. The RPS outputs providebackup power for a NetVanta 1500 or 1600 switch’sinternal power supply. The EPS output provides370 watts of backup PoE for a NetVanta 1500 or1600 PoE switch for PoE redundancy. In addition,the EPS output provides 370 watts of additionalPoE for the NetVanta 1638P for a total of 740 wattsof available PoE budget power.Alternate Power SupplyThe NetVanta 1131 RPS/EPS unit providesredundant power feeds via an alternate AC powercircuit. In this instance, the NetVanta switchis connected to the primary AC circuit, andconnected to NetVanta 1131 RPS/EPS, whichis powered via an alternate AC power source.Should the primary AC circuit fail, theNetVanta 1131 RPS automatically providespower feed to the connected NetVanta switcheliminating any downtime.Internal Power Supply BackupThe NetVanta 1131 RPS output providesredundancy for NetVanta PoE and non-PoEswitches in the event of an internal power supplyfailure. In the event the switch’s internal powersupply fails, the NetVanta 1131 would power theNetVanta switch until the power unit is replaced orswapped out.Redundant PoE BudgetThe NetVanta 1131 EPS output provides externalbackup power supply to the NetVanta 1500 and1600 Series PoE switches, in case the internal PoEpower supply fails. The NetVanta 1131 can provideup to 370 watts of redundant PoE budget to ensurePoE-powered edge devices such as VoIP phones,wireless Access Points (APs) or IP security camerasoperate without interruption.Supplemental PoE PowerThe NetVanta 1131 EPS output can also providesupplemental power up to 370 additional watts,for the NetVanta 1638P Gigabit PoE switch. Thisprovides increased power wattage, effectivelydoubling the available PoE budget, enabling theNetVanta 1638P to support greater number of PoEor PoE+-powered edge devices. The NetVanta 1131EPS’ internal power management enables efficientbudgeting of available PoE power.Key Featuresn Redundant and ExtendedPower Supply forNetVanta switchesn Redundant Power for upto three NetVanta switchesn Enables NetVanta switchesto be powered fromDual AC circuitsn Backup 370 watts PoEbudget power forNetVanta PoE switchesn Additional 370 wattsPoE budget powerfor NetVanta 1638Pn Half-rack form factor,allowing two NetVanta 1131sto be mounted using theoptional dual mounting trayn Plug-and-play operation—requires no manualconfigurationSupportedSwitchesn NetVanta 1534/1534Pn NetVanta 1535Pwith ActivReachn NetVanta 1544/1544Pn NetVanta 1638/1638P withand without ActivChassisNetVanta 1131Redundant /External Power Supply UnitNetVanta 1638PNetVanta 1544NetVanta 1534NetVanta 1131RPS/EPS23STAT25262728RPSVCIDILL428ARedundant PowerRedundant PowerRedundant PowerExternal Power
