Chapter 3 Hardware Overview Table 2 Panel Connections (continued) CONNECTOR DESCRIPTION 24 100 Mbps Fast Ethernet SFP Slots Connect these ports to a computer or switch. ES-3124 and ES-3124PWR 2 100/1000 Mbps RJ-45 Ports Connect these ports to high-bandwidth backbone network Ethernet switches or use them to daisy-chain other switches. Use 1000Base-T compatible Category 5/5e/6 copper cables. ES-3124-4F and ES-3124F 2 Mini-GBIC Ports Use mini-GBIC transceivers in these slots for fiber-optic connections to backbone network Ethernet switches or use them to daisy-chain other switches. ES-3124PWR Power over The 24 10/100 Mbps RJ-45 Ethernet ports are compliant with the IEEE 802.3af power Ethernet (PoE) over Ethernet standard. 3.1.1 Console Port For local management, you can use a computer with terminal emulation software configured to the following parameters: • VT100 terminal emulation • 9600 bps • No parity, 8 data bits, 1 stop bit • No flow control Connect the male 9-pin end of the console cable to the console port of the Switch. Connect the female end to a serial port (COM1, COM2 or other COM port) of your computer. 3.1.2 Ethernet Ports The Switch has 24 10/100Mbps auto-negotiating, auto-crossover Ethernet ports. In 10/ 100Mbps Fast Ethernet, the speed can be 10Mbps or 100Mbps and the duplex mode can be half duplex or full duplex. The Switch also comes with two pairs of Gigabit Ethernet/mini-GBIC ports. The mini-GBIC ports have priority over the Gigabit ports. This means that if a mini-GBIC port and the corresponding Gigabit port are connected at the same time, the Gigabit port will be disabled. The speed of the Gigabit Ethernet ports can be 100Mbps or 1000Mbps and the duplex mode can be half duplex (at 100 Mbps) or full duplex. An auto-negotiating port can detect and adjust to the optimum Ethernet speed and duplex mode (full duplex or half duplex) of the connected device. An auto-crossover (auto-MDI/MDI-X) port automatically works with a straight-through or crossover Ethernet cable. 3.1.2.1 Default Ethernet Settings The factory default negotiation settings for the Ethernet ports on the Switch are: • Speed: Auto • Duplex: Auto ES-3124 Series User's Guide 37
