Power over Ethernet (PoE)
Overview
FTOS supports Power over Ethernet (PoE), as described by IEEE 802.3af, on C-Series and S-Series
systems (S25V and S50V models), as indicated by the
below each command heading.
Commands
This chapter contains the following commands:

power budget
s
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 Force10, and it is attached to the
Current Sharing terminal, you can 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.
Syntax
[no] power budget stack-unit 0-7 321-790
Enter no power budget stack-unit 0-7 to disable the use of power for PoE from the external power
supply on the designated stack member.
Parameters
0-7
321-790
Defaults
320W (i.e., redundancy mode)
power budget

Enter the stack unit ID, from 0 to 7, of the stack member that you want to configure.
After entering the stack unit number, enter a value representing the watts to be used
for PoE.
