This WS-C3750X-48PF-S  switch has 48 10/100/1000 Ethernet ports that support full PoE and can deliver 30W power to each port. It also has four optional network modules that can be used for GE or 10GE uplinks. It is the first in the industry to offer these features in a 1 RU form factor. It has dual modular power supplies and fans for redundancy, as well as MACsec encryption for secure data transmission.

It supports Flexible NetFlow and hardware encryption between switches with the Service Module uplink. It has USB Type-A and Type-B ports for storage and console access, and an out-of-band Ethernet port for management. It uses StackWise Plus technology for 64 Gbps of throughput and easy stack configuration. It is backward compatible with all other Cisco Catalyst 3750 Series Switches for investment protection.
