Page 73 highlights

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

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.
