PoE+ Capability
The WS-C3750X-48P-S is designed for deployments where network devices can receive both data and power through Ethernet.
Typical applications include:
- Cisco IP phones
- Wireless access points
- IP surveillance cameras
- PoE-enabled IoT devices
- Enterprise endpoints
- Network access equipment
The 435W PoE figure is the available system PoE power, so it should not be interpreted as 435W available from every port simultaneously. Actual device support depends on the connected equipment and switch power configuration.
Stackable Enterprise Switch
One of the major benefits of the Catalyst 3750-X platform is its support for Cisco stacking technologies.
StackWise-480 provides high-speed stacking for compatible Catalyst 3750-X configurations, while StackPower allows compatible switches to share power resources. This makes the platform suitable for enterprise networks requiring centralized management and resilient switch deployments.
Suitable Applications
The Cisco WS-C3750X-48P-S can be used for:
- Enterprise office networks
- Campus access networks
- IP telephone systems
- Wireless LAN deployments
- Security camera networks
- Branch-office networking
- Data and voice convergence
- Network equipment replacement
- Legacy Cisco infrastructure
