Overview & Key Features
The WS-C3750X-48P-L is a managed, stackable Gigabit Ethernet switch. It provides 48 Power over Ethernet Plus (PoE+) ports, enabling you to power devices like IP phones, wireless access points, and surveillance cameras directly over the network cable. It includes the Cisco IOS LAN Base software feature set, making it suitable for core Layer 2 and light Layer 3 networking needs.
Key features include:
-
PoE+ Support: Compliant with IEEE 802.3at, it can supply up to 30W per port, supporting next-generation devices while being backward compatible with legacy PoE (802.3af).
-
Cisco StackWise Plus Technology: Allows you to stack up to 9 switches, which then operate and are managed as a single, unified system.
-
Cisco StackPower: An innovative feature that allows power supplies to be shared among all switches in the stack, providing power redundancy and enabling zero-footprint backup power.
-
Energy Efficiency: Supports Cisco EnergyWise, which allows for managing the power consumption of connected devices to reduce operational costs.
-
Modular Uplinks: Features a hot-swappable network module slot, allowing you to add 4x 1G SFP ports or 2x 10G SFP+ ports for uplink flexibility.
