Network Ports ■ 48 auto-sensing 10/100Base-TX ports. All these ports have the "HP Auto MDIX" feature, which means that you can use either straight-through or crossover twisted-pair cables to connect any network devices to the switch. ■ Two dual-personality ports. You can use either the 10/100/1000Base-T RJ-45 connector, or install a supported HP Procurve mini-GBIC for fiberoptic connections. The RJ-45 connectors support the IEEE Auto MDI/MDI-X feature, which operates the same as the "HP Auto-MDIX" feature. Dual-Personality Port Operation. By default, the RJ-45 connnectors are enabled. If a mini-GBIC is installed in a slot, it is enabled and the associated RJ-45 connector is disabled and cannot be used. If the mini-GBIC is removed, the associated RJ-45 port is automatically re-enabled. 1-2
