Chapter 1: Overview

The x600-24Ts-POE smart power management functionality supports any combination of Ethernet ports (1-24) that supply power for IEEE 802.3af Class 0, 1, 2, or 3 powered devices up to a maximum of 370 watts, as described in Table 9.

*The Maximum Power Level Output levels reflect the loss introduced by a 100 meter Ethernet cable between the Power Source Equipment (PSE) and the Power Device (PD).

A port connected to a network node that is not a powered device functions as a regular Ethernet port, without PoE. The PoE feature remains enabled on the port but no power is delivered to the device.

Note

The PoE power supplied from ports 21R, 22R, 23R and 24R is unaffected by insertion of an SFP module in to the corresponding SFP combo port.

Implementation A standard Ethernet twisted pair cable contains four pairs of strands for a total of eight strands. When 10/100 Mbps network traffic is present, only four strands (1, 2, 3, and 6) are required, which leaves four strands in the cable unused (4, 5, 7, and 8). When 1000 Mbps network traffic is present, all eight conductors in the cable are required.

The PoE standard, IEEE 802.3af, describes two alternative ways for delivering power to a powered device (PD) over twisted pair cabling. Alternative A uses the same strands that carry the 10/100 Mbps network traffic. Alternative B uses the spare strands for 10/100 Mbps network traffic. The PoE implementation on the x600-24Ts-POE Gigabit Ethernet Switch is Alternative A, where power and 10/100 Mbps network traffic is transmitted over strands 1, 2, 3, and 6.
