I want to connect multiple 2960's to the Cisco WS-C3750-24FS-S (24
100BASE-FX ports). My question is can I use the SFP GLC-FE-100FX=
module to shoot 100Mbps to the 3750?? And yes it HAS to be fiber
connections!

Yes for the -TC models
http://www.cisco.com/en/US/products/hw/modules/ps5455/products_device_support_table09186a0080380847.html#wp51054
But that table is out of date and does not mention the -TT models
at all. And the gigabit equivilent table claims no support for the
gigabit GLC's on the 2960s, which is clearly wrong according to the
current product documentation which speaks of gigabit SFPs.
So, what you can look at is:
http://www.cisco.com/en/US/products/ps6406/products_data_sheet0900aecd80322c0c.html
and scroll down about 40% to "Ease of Use and Deployment", and notice
there that it says,
1000BASE-SX, 1000BASE-LX/LH, 1000BASE-ZX, 1000BASE-BX, 100BASE-FX,
100BASE-LX, 100BASE-BX, and coarse wavelength-division multiplexing
(CWDM) physical interface support through a field-replaceable SFP
module provides unprecedented flexibility in switch deployment.
this -implies- that there is currently 100BASE-FX SFP support on
all of the 2960s that have SFPs. But if you happen to have a -TT
then likely it would be better to cross-check with Cisco in case this
is a feature not yet available on those devices.
