Figure 2-1 through Figure 2-5 show the Catalyst 3750 switches.
These are the switch features:
• Hardware
– Catalyst 3750-24TS—24 10/100 Ethernet ports and 2 small form-factor
pluggable (SFP) module slots
– Catalyst 3750G-24T—24 10/100/1000 Ethernet ports
– Catalyst 3750G-24TS—24 10/100/1000 Ethernet ports and 4 SFP
module slots
– Catalyst 3750-48TS—48 10/100 Ethernet ports and 4 SFP module slots
– Catalyst 3750G-12S—12 SFP module slots
• The switches support these SFP modules:
– 1000BASE-SX
– 1000BASE-LX
– 1000BASE-T
Note When installed in Catalyst 3750 switches, 1000BASE-T small
form-factor pluggable (SFP) modules can either operate at 10, 100, or
1000 Mbps in full-duplex mode or in half-duplex mode at 10 or 100
Mbps.
• Configuration
– For 10/100 ports, autonegotiates the speed and duplex settings
– For 10/100/1000 ports, autonegotiates the speed and supports only
full-duplex mode
• The Catalyst 3750 switches support stacking. You can stack up to nine
switches in a stack by cabling the StackWise ports. StackWise ports are not
user-configurable.
• Switches are hot-swappable
• Power redundancy
– Connection for optional Cisco RPS 300 redundant power system that
operates on AC input and supplies backup DC power output to the
Catalyst 3750-24TS, 3750G-24T, 3750-48TS, and 3750G-12S switches.
