24-Port 10/100 + 2-Port Gigabit Switch with Webview and Power over Ethernet Port Status This screen allows you to view the status of a port. The Port, Enable, Link Status, Spd/Dpx, and Flow Control are displayed. Ports 1 through 24 are ethernet RJ-45 ports and ports 25 and 26 are Gigabit RJ-45 ports, Giga1 and Giga2. Each Gigabit port has a shared mini-Gbic port. If there is a connection to one of the mini-Gbic ports then the corresponding Gigabit RJ-45 port cannot be used. Port Configuration You can use the Port Configuration or screen to enable/disable an interface, set auto-negotiation and the interface capabilities to advertise, or manually fix the speed, duplex mode, and flow control. Enable - Allows you to manually enable or disable an interface. You can disable an interface due to abnormal behavior (for example, excessive collisions), and then enable it again, once the problem has been resolved. You may also disable an interface for security reasons. Auto-negotiation (Port Capabilities) - Allows auto-negotiation to be enabled/disabled. When auto-negotiation is enabled, you need to specify the capabilities to be advertised. When auto-negotiation is disabled, you can force the settings for speed, mode, and flow control.The following capabilities are supported. • 10half - Supports 10 Mbps half-duplex operation • 10full - Supports 10 Mbps full-duplex operation • 100half - Supports 100 Mbps half-duplex operation • 100full - Supports 100 Mbps full-duplex operation • 1000full (Gigabit only)- Supports 1000 Mbps full-duplex operation (Default: Autonegotiation enabled; Advertised capabilities for 100BASE-TX - 10half, 10full, 100half, 100full; 1000BASE-T - 10half, 10full, 100half, 100full, 1000full; 1000BASE-SX/LX/LH (SFP) - 1000full; 100BASE-FX (SFP) - 100full Speed/Duplex. Allows manual selection of port speed and duplex mode (that is, with auto-negotiation disabled). Flow Control. Allows automatic or manual selection of flow control.
