Using the Centillion EtherSpeedII Switch Modules

Hot-Swapping Capability

You can insert EtherSpeedII switch modules into or remove them from a chassis without interrupting service to other modules within the Centillion 50/100 chassis. This feature is called “hot-swapping.”

Caution: Be sure to remove cables from all ports on the module, or disable all the ports through the management interface, prior to hot-swapping.

10/100 Mb/s Autonegotiation Ports

The EtherSpeedII 10/100BASE-T switch module contains 20 10/100 Mb/s UTP autonegotiating Ethernet ports with shielded RJ-45connectors. The RJ-45 connectors accept Category 3 or 5 unshielded twisted pair (UTP) cable or shielded twisted pair (STP) cable and are wired as MDI-X ports to connect end stations to patch panels without using crossover cables.

Note: See Appendix B, “Cables and Connectors,” for information about wiring and pin assignments.
