114 | System Configuration Commandsw w w . d e l l . c o m | s u p p o r t . d e l l . c o mPoE CommandsSFTOS software, starting with version 2.5.1, supports Power over Ethernet (PoE) functionality on theS50V switch. The commands that support PoE are:• inlinepower on page 114• inlinepower threshold on page 115• inlinepower admin on page 115• inlinepower priority on page 116• inlinepower limit on page 116• inlinepower type on page 116• show inlinepower (stack) on page 117• show inlinepower on page 118In addition to PoE commands in the CLI, SFTOS support for PoE through SNMP is by thePower-Ethernet MIB.PoE provides the ability to transmit both electrical power and data to remote devices over standardtwisted-pair cable. SFTOS support for PoE conforms to IEEE 802.3af, which defines a standard todeliver power over Ethernet cables.All 48 physical copper interfaces on the S50V have the capability to provide power. Some of thesalient features are as follows:• The maximum power available for PoE on the switch is 360 watts, subject to factors such as otherswitch requirements. The minimum available is 320 watts. Each port can provide a maximum of20 watts, subject to the power budget, voltage, and user settings for power priority and powerlimits per port and per switch in a stack. See inlinepower priority on page 116 and inlinepowerlimit on page 116.• Legacy devices, as well as powered devices specifically compliant with 802.3af, are supported.• When the power budget is exceeded, the next port attempting to power up causes the currentlyenabled port with the lowest priority to shut down if the port attempting to power up has a higherPoE priority.inlinepower Enable or disable the PoE feature for a specified switch in an S-Series stack.Syntax inlinepower {disable | enable} unit-idParametersDefaults EnableMode Global ConfigCommandHistorydisable | enable Enter one or the other keyword to disable or enable PoE.unit-id Enter the stack member ID of the switch to which you want to change thePoE setting.Version 2.5.1 Introduced
