The BayStack 420-24T Switch is a stackable 10/100/1000 layer 2 Ethernet switch featuring easy configuration and stackability, flexible choices for high-speed uplinks, and web-based management from a Web browser. Combining high-port density with lower per-port pricing for a cost-effective switching solution, the BayStack 420 is designed for the requirements of small- to medium-sized businesses and branch offices. Each BayStack 420-24T Switch has 24 10BaseT/100BaseTX autosensing ports, one GBIC-based (Gigabit Interface Converter) uplink slot and built-in stacking connectors. It can be used as a standalone switch or in a stack of up to 8 switches (up to 192 ports) that can be easily managed as a single entity. Advanced features such as VLAN support, MultiLink Trunking, Simple Network Management Protocol (SNMP) and Web-based management tools help Network Managers to efficiently control network traffic. Built-in Gigabit stacking connectors provide easy connections to other switches in the stack and save money by not requiring additional cascade modules. The scalable architecture is designed to protect your network investment, as your business grows. BayStack 420-24T Switch offers a built-in GBIC (Gigabit Interface Converter) slot that provides high-speed connection to backbone switches or servers. A variety of GBIC module options gives you flexibility in fiber interfaces to connect to distant servers or a larger network, including SX, LX, XD (50 km) and ZX (70 km) for long haul connectivity.
