Which switch model

[ola.salam]

Need switch gigabit 24 ports and 48 ports excluding ports to connect fibre optic cables... what are the models?

[Leo Laohoo]

Nearly all switch models can do Gigabitethernet with SFP uplink ports:

2960G (24/48, PoE or Non-PoE);

2975GS (48-ports PoE only);

3550G/3550-E (24/48, PoE or Non-PoE. -E's can do 10Gb uplink); and

3750G/3750-E (24/48, PoE or Non-PoE. -E's can do 10Gb uplink)

The list does not include the chassis-based: 4500/6500/7500 series etc. etc. etc.

Do you have a specific requirement?
