Cisco Systems 3750-X, 3560-X manual Network Modules

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 1-17for 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.
