Chapter 1 Product Overview
Front Panel Description
Note You can configure duplex mode to half, full, or autonegotiate on Gigabit Ethernet interfaces
if the speed is set to 10 or 100 Mb/s. You cannot configure half-duplex mode on Gigabit
Ethernet interfaces if the interface speed is 1000 Mb/s.
• 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.
• Connection for an optional Cisco RPS 2300 or Cisco RPS 675 redundant power system (RPS) that
operates on AC input and supplies backup DC power output to the Catalyst 3750 switches. The
Catalyst 3750G-12S-SD switch does not support an RPS.
