Hardware Description Device Port Configurations PowerConnect 54xx Series Systems Front Panel Port Description The PowerConnect 54xx series systems are configured with the following ports: • 24/48 Copper ports - RJ-45 ports designated as 10/100/1000 BaseT Gigabit Ethernet ports • 4 Fiber ports - Designated as Gigabit ports • Terminal port - RS-232 console based port The following figure illustrates the PowerConnect 54xx series systems front panel. Figure 2-1. PowerConnect 5424 Front Panel The front panel contains ports1-24/48, which are copper based RJ-45 ports, designated as 10/100/1000 Mbps and support both Half and Full Duplex modes. There are four SFP fiber ports which are designated as Combo ports 21-24/45-48. A Combo port is a single logical port with two physical connections. Only one physical connection can be active at a time, so either the copper ports or the equivalent fiber ports 21-24 can be active, but they cannot both be active simultaneously. The upper row of ports are marked by odd numbers and the lower row of ports are marked with even numbers. On the front panel are all the device LEDs and a Reset Button which is used to manually reset the device. The device automatically detects whether the cable connected to an RJ-45 port is crossed or straight through, and functions either way. Hardware Description 25
