Three SSA models—SSA-T4068-0252, SSA-T1068-0652, and SSA-T1068-0652A—support both IEEE 802.3af and 802.3at Power over Ethernet (PoE) standards, with up to 1500 watts available for PoE. Depending on your power supply configuration, the SSA-T4068-0252, SSA-T1068-0652, and SSA-T1068-0652A can supply PoE power to powered devices on all 48 RJ45 ports simultaneously.
The red PoE button switches the RJ45 port LEDs to report PoE information. In PoE mode, the PWR LED changes to indicate the power supplies installed in the SSA. For more information, see RJ45 Port LEDs—PoE Mode.
