The HOME page displays. 4. Select POE. The Power over Ethernet (PoE) page displays. 5. To enable or disable the uninterrupted PoE feature, click the Uninterrupted POE button: • Disabled: The button bar displays gray and the button is positioned on the left.
Gigabit Ethernet Plus Switches The port priority determines which ports can still deliver power after the total power delivered by the switch exceeds the total power budget. (In such a situation, the switch might not be able to deliver power to all connected devices.) If the same priority applies to two ports, the lower-numbered port receives higher priority. 10. From the Power Mode menu, select the PoE mode in which the port must function: • 802.3af: The port is powered in and limited to the IEEE 802.
Gigabit Ethernet Plus Switches 12. From the Detection Type menu, select one of the following options: • IEEE 802: The port performs a 4-point resistive detection. This is the default setting. • 4pt 802.3af + Legacy: The port performs a 4-point resistive detection, and if required, continues with legacy detection. • Legacy: The port performs legacy detection. 13. Click the APPLY button. Your settings are saved.
Gigabit Ethernet Plus Switches • Temperature: The temperature in degrees Celcius. • Fault Status: The error description when the PoE port is in a fault state: - No Error: The port is not in any error state and can provide power. - MPS Absent: The port detected the absence of the main power supply, preventing the port from providing power. - Short: The port detected a short circuit condition, preventing the port from providing power.

7 Diagnostics and Troubleshooting This chapter covers the following topics: • • • Test cable connections Resolve a subnet conflict to access the switch PoE troubleshooting suggestions 86
Gigabit Ethernet Plus Switches Test cable connections You can use the cable diagnostic feature to easily find out the health status of network cables. If any problems exist, this feature helps quickly locate the point where the cabling fails, allowing connectivity issues to be fixed much faster, potentially saving technicians hours of troubleshooting. If an error is detected, the distance at which the fault is detected is stated in meters. (This is the distance from the port.) To test cable connections: 1.
Gigabit Ethernet Plus Switches be different from the subnet used in your network. You might see the following message if you try to access the switch: The switch and manager IP address are not in the same subnet. To resolve this subnet conflict: 1. Disconnect the Ethernet cable between the switch and your network. 2. Shut down power to the switch. 3. Reconnect the Ethernet cable between the switch and your network. 4. Reapply power to the switch. The switch powers on.
