The Catalyst Center Power over Ethernet (PoE) enables you to monitor the PoE-capable devices in your network. It also monitors the power summary of switches supplying PoE, which provides information such as a switch's power budget, used power, remaining power, and power usage. We use a Moduletek SFP-GE-SX optical module installed on a Fortinet FS-108D-PoE switch as an example to show the detailed operation steps. On the Ports tab, you can view the visual status and detailed status of the switch ports. The PoE tab displays the following details: To navigate to the PoE tab in the Switch dashboard, complete the following steps: In the WebUI, set the filter to one of the options under.
