FEATURE HIGHLIGHTS AND MODEL COMPARISON
UNDERSTANDING THE POWER OPTIONS
Power to the IntelliJack Gigabit Switch can be supplied through either PoE (IEEE 802.3at or 802.3af) applied
to the uplink port or through the optional local external power supply. If power is supplied to the uplink
port by 802.3at or by the external power supply, then ports 1 and 2 may act as PoE Power Source Equipment
(PSE) and may also provide power to other devices plugged into those ports. If power is supplied by 802.3af,
then ports 1 and 2 will not be able to supply PoE power. Refer to the below table for a summary.
