User Manual
FAQ
What is the total PoE budget of this switch?
The Transition Networks SESPM1040-541-LT-DC provides a total PoE budget of 240 watts. This budget supports IEEE 802.3at (PoE+), 802.3af (PoE), and 802.3bt (PoE++) standards, allowing it to power high-demand devices like PTZ cameras, wireless access points, and VoIP phones across its four PoE++ ports. The switch dynamically allocates power based on connected device requirements, with up to 90W available per port for PoE++ devices.
How many SFP slots does this switch have?
This switch includes one shared SFP (mini-GBIC) slot, which is configured as a Gigabit Ethernet TP/SFP combo port. The combo port allows you to use either the RJ-45 copper interface or an SFP transceiver for fiber optic connectivity, but not both simultaneously.
