Switch Overview 1 Switch Overview Switch Hardware Features The ProCurve Switch 1800-24G (J9028A) is a multiport switch that can be used to build high-performance switched workgroup networks. This switch is a store-and-forward device that offers low latency for high-speed networking. Power LED Port Link/Act and Mode LEDs ProCurve Switch 1800-24G Fault LED LED Mode Select button and indicator LEDs 10/100/1000Base-T RJ-45 ports Dual-personality ports (10/100/1000Base-T or mini-GBIC) Switch Ports The switch has 24 auto-sensing 10/100/1000Base-T RJ-45 ports and two dualpersonality ports (ports 23 and 24). Because the RJ-45 ports support automatic MDI/MDI-X operation, you can use straight-through cables for all network connections to PCs or servers, or to other switches or hubs. Dual-personality ports use either the 10/100/1000Base-T RJ-45 connector, or a supported ProCurve mini-GBIC for fiber-optic connections. By default, the RJ45 connectors are enabled. This switch is designed to be used primarily as a high-density wiring closet or desktop switch. With this switch you can directly connect computers, printers, and servers to provide dedicated bandwidth to those devices, and you can build a switched network infrastructure by connecting the switch to hubs, other switches, or routers. In addition, the switch offers network management capabilities. 1-1
