GS728TS, GS728TPS, GS752TS, and GS752TPS Gigabit Smart Switches • High Power Mode. Select the power-up mode for the port • Disable: A port is powered in the IEEE 802.3af mode. (Default) • Legacy: A port is powered using high-inrush current, which is used by legacy powered devices (PDs) with a power requirement greater than 15W from power up. • Pre-802.3at. A port is powered in the IEEE 802.3af mode initially and switched to the high-power IEEE 802.3at mode before 75 msec. Use this mode if the PD is not performing Layer 2 classification, or if the switch is performing two-event Layer 1 classification. • 802.3at. A port is powered in IEEE 802.3at mode. If the PD class detected by the switch is not Class 4 (type 2), the port will power up the PD, but only Class 4 PDs can be powered up in the IEEE 802.3at mode. • Power Limit Type. Select the type of power limit to use on the port, which is one of the following: • Class: Select this option to base the power limit on the detected class value. When this value is selected, the user-configured value configured in the Power Limit field is ignored. • User: Select this option to base the power limit on the value configured in the Power Limit field. • None. Select this option to indicate that no power limit type is used on the port. • Power Limit. Set the maximum amount of power that can be delivered by a port when the Power Limit Type is User. • Detection Mode. Select the PD detection mode the PSE port uses to detect an attached device. The detection mode can be one of the following modes: • Auto. The port performs four-point resistive detection (802.3af4point) followed by legacy detection. • Pre-ieee. The port performs legacy detection. • ieee. The port performs four-point resistive detection (802.3af4point). • Class. View the class of the PD connected to the port. The class defines the range of power a PD is drawing from the system. The class is defined as: • 0: 0.44-12.95W • 1: 0.44-3.83W • 2: 3.84-6.48W • 3: 6.49-12.95W • 4: 12.95-25.50W (802.3at Type 2 devices only) • Timer Schedule. Select the timer schedule to use for the port. By default, no timer schedules are configured. To create a timer schedule, use the Timer Schedule Global Configuration page. • Output Voltage. Shows the current voltage being delivered to device in Volts. • Output Current. Shows the current being delivered to device in mA. • Output Power. Shows the current power being delivered to device in Watts. 73
