10/100/1000 BASE-T ports

All devices provide 24 or 48 RJ-45 ports that operate at 10 Mbps or 100 Mbps half or full duplex, or at 1000 Mbps full duplex. Because all ports support automatic MDI or MDI-X operation, you can use straight-through cables for all network connections to PCs, servers, or other devices or hubs. In addition, it is ideal (and preferred) to use straight-through cables for switch-to-switch connections.

Each port supports auto-negotiation, so the optimum transmission mode (half or full duplex), and the data rate (10, 100, or 1000 Mbps) can be selected automatically. If a device connected to one of these ports does not support auto-negotiation, the communication mode of the port can be configured manually.
