The port status LEDs have two display modes: Link and PoE. The Link mode

displays the link status and network activity on each port. The PoE mode displays

the PoE power status on each port. Use the Mode Link/PoE button (see "Mode PoE/

Link Button" on page 1-6) on the front panel to toggle between the two display

modes. The current mode is indicated by the Link/Act and PoE system LEDs.
