Compaq HB 3321

Compaq HB 3321 ... ideally suited for customers with networks running both 10Mbps and 100Mbps, and who intend to gradually upgrade more users to Fast Ethernet. Both hubs run 10Mbps and 100Mbps with auto-negotiating on every port, and a single switching module supports 10Mbps with 100Mbps connectivity for the entire stack.

The hubs stack six units high, providing the most cost-effective dual-speed, high-port density available today. With 12 ports (3320) and 24 ports (3321) per unit, the hubs allow for up to 144 dual-speed, managed ports in a single stack, which allows for future network expansion. Because these hubs are Class II compliant, users can double the size of the network simply by connecting to another stack for a total of 288 ports. Also, if users need a high level of network resiliency, users can add more than one SNMP management module and switch module to a stack for full switch and management redundancy.
