1. Introduction “Inline power” is a feature offered on some Ethernet switches. It is a means by which the switch can supply power to a network device within the same cable that carries the Ethernet signaling. This simplifies network installation and powering design, removing the need for a separate power supply for each IP telephone in the network. IEEE 802.3af-2003 defines a standard protocol to be used by powering and powered devices. The 3Com SuperStack 3 Switch 4400-PWR is a 24-p

• Disabled — The port has been configured not to supply power. • FAULT — The port is in error. Profile The Profile that has been selected for a port. This can take one of the following values: • Guaranteed — The device on the port has power reserved for it, as listed in the Limited To column. • Not Guaranteed — The device on the port has no power reserved for it. It will receive power if the switch is below its maximum power budget, and all ports with higher

3. Figure 6: Display Inline Power Status Configure port power profile. By default, the maximum power for all ports is not guaranteed. To guarantee that PDs get their specified maximum power, their profile can be configured using the Guaranteed profile. Guaranteeing Power on a Port To guarantee power to a port: In the Port column, select the port or ports that are guaranteed for power. In the drop-down box: • Select the profile that corresponds to the

For example, follow the steps above to change ports 1-3 to use the guaranteed profile. Figure 7 shows all three ports are configured to use the Guaranteed profile. Note the power limit is set to 15.4 watts for ports 1 and 2, and 7 watts for port 3, since both the 4620 and 4612 IP telephones are class 3 devices and the 4602SW IP phone is a class 1 device. Table 2 shows the required power allocations defined by IEEE 802.3af-2003, based on the class. Class Usage Power (Watts) 0 Def
