The high-densitySummit7i stackable switch delivers non-blocking wire-speed IP/IPX routing and switching to server farms, aggregated switches and network backbones. Available with 28 100/1000BASE-T or 1000Base-SX ports plus four GBIC-based 1000Base-X ports, Summit7i is the industry's first stackable 32-port Gigabit Ethernet switch in a compact '4U' package. In server farms and data centers, the Summit7i maximizes server availability and performance by combining server load-balancing with wire-speed switching. Auto-negotiating 100/1000Base-T ports extend the simplicity of Ethernet's scalable speed from Fast Ethernet to Gigabit Ethernet. The low 7-inch height of the Summit7i also makes it ideal in server farms and data centers where rack space is limited.
