Chapter 1 Product Overview
Front Panel Description
• Configuration for StackPower PoE+. When the switch internal power supply module(s) cannot
support the total load, StackPower configurations allow the switch to leverage power available from
other switches (only Catalyst 3750-X switches)
• Configurable support for Cisco intelligent power management, including enhanced power
negotiation, power reservation, and per-port power policing
Depending on the installed power supply modules, each port can deliver up to 30 W of PoE+. See
Table 1-17 for the power supply matrix that defines the available PoE and PoE+ power per port.
Note The output of the PoE+ circuit has been evaluated as a Limited Power Source (LPS) per IEC 60950-1.
For information about power supply modules, PoE+ port connections, and PoE+ specifications, see the
“Power Supply Modules” section on page 1-17, the “PoE+ Port Connections” section on page 2-28, and
Appendix B, “Connector and Cable Specifications.”
Network Modules
The switch has one hot-swappable network module that provides SFP and SFP+ uplink ports to connect
to other devices. You must insert the network module during switch operation. Operating the switch
without a network module is not supported. A blank module is available.
The switch generates logs when you insert or remove a network module with SFP ports.
