Power over Ethernet (PoE) and Power over

Ethernet Plus (PoE+)

Overview

Dell Networking OS supports Power over Ethernet (PoE) on C-Series and S-Series systems (S25V and

S50V models) as described by IEEE 802.3af. Dell Networking OS supports Power over Ethernet Plus

(PoE+) on the C-Series system, as described by IEEE 802.3at.

Refer to the c and s characters that appear below each command heading. If a command supports

both PoE and PoE+, PoE supports the S-Series.

Commands

This chapter contains the following commands:

• power budget

• power inline

• power inline priority

• show power detail

• show power inline

• show power supply

power budget

If an S25V or S50V model of the S-Series has an external power supply, this command allows the

external power supply of the specified stack member to be used for powering PoE ports. An external

DC power supply operates, by default, in Backup mode. However, if the power supply is the 470W

Redundant Power Supply (catalog # S50-01-PSU-V) from Dell Networking, and it is attached to the

Current Sharing terminal, use this command to convert its use to Load-Sharing mode to support

additional PoE devices. Other external DC power supplies are not supported for PoE.

SSyntax

[no] power budget stack-unit 0-7 321-790

To disable the use of power for PoE from the external power supply on the designated stack member,

enter no power budget stack-unit 0-7.
