I am ordering a WS-C3750G-12S-S
. We need to connect it with a cat 5 cable. Because the specs for this switch say it has 12 SFP-based Gigabit Ethernet ports. Does that mean I should be able to connect this with a normal RJ45 connector ? I am goignt to buy 11 SFP's I need to conenct to 11 other switches. But one of the port will connect to a 2800 series router and our only choice is to connect this with a RJ45 as we do not have access to that router. Will there be any interfaces I will need to buy to connect one of the sfp port with RJ45 ?
Yes you are going to need a 1000BaseT SFP - part number GLC-T=. This provides a standard RJ45 connector and operates at 10/100/1000 on the 3750.
