Dual Redundant Modular Power Supplies
Cisco Catalyst 3750-X Series and 3560-X Series Switches support dual redundant power supplies (Figure 2);
One power supply is shipped with the switch by default;
Other power supply/suppliers can be purchased when ordering the switch or next time according to your needs.
If only one power supply is installed, it should always be in the power supply bay 1.
Table below shows the different power supplies available in these switches and available PoE power.

Please recommend what 3750 is best for 100 users.
Only one 3750 device cannot meet 100 users’ needs. For your request we think 2*WS-C3750X-48T-L & 1*WS-C3750X-25T-L stack is the best idea.
Can SFP port connect with GBIC module?
NO, GBIC is mini SFP module.
With the power switch on, only the fan operate, but no other function on. How can I work with it?
The fan is connected directly to the DC outputs of the power supply.Pls check the motherboard.
