Nortel Networks manual Uplink/Expansion ModuleSlot, 10BASE-T Port Connectors

Introduction to the BayStack 410-24T Switch

Note: The Console/Comm Port is configured as a data communications equipment (DCE) connector. Ensure that your RS-232 cable pinouts are configured for DCE connections (see “DB-9(RS-232-D) Console/Comm Port Connector” on page D-5).

The console port default settings are: 9600 baud with eight data bits, one stop bit, and no parity as the communications format, with flow control set to Xon/Xoff.

Uplink/Expansion ModuleSlot

The Uplink/Expansion Module slot allows you to attach optional media dependent adapters (MDAs) that support a range of media types (see Appendix B, “Media Dependent Adapters” for more information about MDA types available from Nortel Networks).

10BASE-T Port Connectors

Your BayStack 410-24T switch uses 10BASE-T (8-pin modular) port connectors.

All BayStack 410-24T switches are shipped with port connectors configured as MDI-X (media-dependent interface-crossover). These ports connect over straight cables to the network interface controller (NIC) card in a node or server, similar to a conventional Ethernet repeater hub. If you are connecting to another Ethernet hub or Ethernet switch, you need a crossover cable unless an MDI connection exists on the associated port of the attached device (see “MDI and MDI-X Devices” on page D-2).

Your switch ports support half- and full-duplex mode operation and use RJ-45 port connectors to connect to 10BASE-T Ethernet segments or nodes (see also “Connecting 10BASE-T Ports and 10/100 MDA Ports” on page 2-8).

Note: 10BASE-T/100BASE-TX MDA ports (optional) must use Category 5 UTP cable to accommodate the 100BASE-TX functionality.

See Appendix D, “Connectors and Pin Assignments,” for more information about the RJ-45 port connectors.
