PoE over SFP port on Cisco 3750 with GLC-T 1000Base-T Copper SFP Module

Sam Brynes

I was looking on Cisco for a 3750 switch with PoE and gigabit ethernet (not SFP) ports, but they are few and far between. I want to connect a Cisco VoIP phone and a Cisco PoE access point via cat5e to the switch and have them powered by PoE.

Since Cisco 3750s with non-SFP gigabit Ethernet ports are hard to find, I was wondering if I could buy a 3750 with SFP ports and buy two

GLC-T 1000Base-T SFP transceivers to get two gigabit Ethernet ports and then power the VoIP phone and access point that way? Is PoE supported on SFP ports like that with the copper SFPs inserted?

There are a few Cisco 3750 POE with 10/100/1000 ports

here is one

WS-C3750G-24PS-S

This switch will give you 24 POE port at 10/100/1000 speed copper.  It also comes with 4 SFP ports for uplink.

POE is only through copper ports.  Fiber ports don't provide POE.

Here is the data sheet:
