48 Chapter 4 Seven-port autosensing switch specifications209374-ASwitch featuresThe Instant Internet 100-S unit seven-port switch offers:• Seven RJ-45 10BASE-T/100BASE-T autosensing Ethernet ports withautonegotiation capability. The eighth port is used internally to connect to theinternal Ethernet controller.• Comprehensive 10/100 Link/Activity LEDs indicating link and activitystatus.• Full-duplex (FDX) and half-duplex (HDX) mode support with one indicatorLED per port.• MDI (uplink, or crossover)/MDI-X (normal, or straight-through) autosensingcapability.• Store-and-forward switching architecture.• One MB buffer memory.When you plug an Ethernet cable into a port, the switch:• Autosenses the transmission speed (10 Mb/s or 100 Mb/s) of the connecteddevice.• Autonegotiates with the connected device to operate in full- or half-duplexmode. If the connected device is operating in half-duplex mode only, or doesnot have the capability to participate in the autonegotiation process, the portdefaults to half-duplex mode.• Autosenses whether the cable is MDI or MDI-X.RJ-45 10BASE-T/100BASE-TX Ethernet portsThe RJ-45 10BASE-T/100BASE-TX Ethernet ports connect the switch tonetwork devices using standard unshielded twisted pair (UTP) cable. The InstantInternet 100-S switch does not support shielded twisted-pair (STP) cable.
