Chapter 3 Hardware Overview
The following table describes the port labels on the front panel.
Table 1 Front Panel Connections
| LABEL | DESCRIPTION |
| 8 100/1000 | Connect these 1Gbps Electrical Ethernet ports to high-bandwidth backbone network |
| Mbps RJ-45 | Ethernet switches or use them to daisy-chain other switches. |
| Ethernet Ports | |
| (GS-3012) | |
| | |
| 8 Mini-GBIC | Use mini-GBIC transceivers in these slots for fiber-optic connections to backbone |
| Slots (GS- | Ethernet switches. |
| 3012F) | |
| | |
| Four Dual | Each interface has one 1000 Base-T copper RJ-45 port and one Small Form-Factor |
| Personality | Pluggable (SFP) fiber port, with one port active at a time. |
| Interfaces | |
| • 4 100/1000 Mbps RJ-45 Gigabit Ports: |
| |
| | Connect these Gigabit Ethernet ports to high-bandwidth backbone network |
| | Ethernet switches. |
| | |
| | • 4 Mini-GBIC Slots: |
| | Use mini-GBIC transceivers in these slots for fiber-optic connections to backbone |
| | Ethernet switches. |
| | |
| Console Port | The console port is for local configuration of the Switch. |
| | |
| Management | Connect to a computer using an RJ-45 Ethernet cable for local configuration of the |
| Port | Switch. |

3.1.1 Console PortFor 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 Gigabit PortsThe Switch has 1000Base-T auto-negotiating, auto-crossover Ethernet ports. In 10/100/1000 Mbps Fast Ethernet, the speed can be 10 Mbps, 100 Mbps or 1000 Mbps and the duplex mode can be half duplex or full duplex.
An auto-negotiating port can detect and adjust to the optimum Ethernet speed (10/100/1000 Mbps) 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.
