Product Description
The 3Com 3CR17343-91, also known as the 4210 PWR series, is a versatile 24-port Fast Ethernet switch designed to provide both network connectivity and Power over Ethernet (PoE) capabilities for small to medium-sized businesses. The 24 copper ports operate at 10/100 Mbps and are capable of delivering PoE, allowing network administrators to power devices such as IP phones, wireless access points, and security cameras directly over the Ethernet cable, simplifying installation and reducing the need for separate power adapters. This switch offers a total switching capacity of 8.8 Gbps and a forwarding rate of 6.5 million packets per second, ensuring efficient data flow for typical office network traffic. It operates at Layer 2, providing fundamental switching functions. For network expansion or connection to higher-speed backbone networks, it includes two SFP combo ports. These ports can be used with SFP transceivers for fiber optic connections or as standard RJ45 ports, offering flexibility in network design. The combo nature means that when an SFP module is used, the corresponding copper port is disabled. Packaged in a 1U rackmount form factor, the 3CR17343-91 is designed for easy integration into standard network racks. While often deployed as an unmanaged switch for simplicity, some variants might offer basic managed features. The PoE capability is a key differentiator, making it a cost-effective solution for businesses looking to deploy IP telephony or wireless infrastructure without extensive cabling modifications. The 3Com brand, now part of HP, signifies a legacy of reliable networking hardware.
