PoE LEDs
The AT-GS950/8POE switch has four PoE ports and four corresponding
PoE LEDs. The PoE LEDs signal a connection to a powered device and if
the port exceeds its power budget. The PoE LEDs apply to ports 1 through
4. For more information about PoE, see “Power over Ethernet” on
page 22.
Table 3 describes the LEDs for the PoE ports.
