ProSafe M5300 Switch
To configure PoE Port settings:
1. Select the check box next to the port to configure. Select multiple check boxes to apply
the same settings to each selected port. Select the check box in the heading row to
apply the same settings to all ports.
2. Configure or view the settings:
• Admin Mode. Enable or disable the ability of the port to deliver power.
• High Power. Indicates whether the port supports High Power Mode.
• Max Power. Shows the maximum power, in Watts, the port can provide.
• Port Priority. Determine which ports can deliver power if the total power delivered by
the switch crosses a certain threshold. The switch may not be able to supply power to
all connected devices. Priority is used to determine which ports can supply power.
When ports have the same priority, the lower numbered port is given a higher priority.
The possible priority levels are Critical (highest priority), High, and Low.
• 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 Type. 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).
