Dell EMC Configuration Guide for the S3100 Series 9.14.2.4

Manage Inline Power

By default, PoE/PoE+ is disabled.

To manage the inline power supplied to the ports, use the power inline mode command in Configuration mode.

This command has the following parameters.

• class — When you configure class mode, the maximum power for the particular class of device is allocated. Class mode supports power allocation through Layer 2 classification and power negotiation by the LLDP 802.3at standard. You can use this mode to configure port priority.
• static — When you configure static mode, the inline power is allocated based on the actual power consumed by the powered device. The power the PD requests is allocated and is reduced from the available pool. Power negotiation through LLDP (extended power via MDI TLVs or IEEE 802.3 at power-via-mdi TLVs) is not supported in static mode. Ports you configure in Static mode reserve a fixed power allocation whether a device is connected or not. By default, 15.4 W is allocated for PoE and 30.0 W for PoE+. No dynamic PoE/PoE+ class detection performs on Static ports. The default Power Management mode is static.
  NOTE The power inline max_milliwatts command enables the inline power supplied to an interface. The max_milliwatts option works only when you use Static mode. When you enable Class mode, the max_milliwatts option has no effect on the interface. Instead, the maximum limit in Class mode applies to the ports.
• stack-unit unit-number — Specify the stack unit number. The range is from 1 to 12.
