About the Passport 8100 Modules

Passport 8148TX 48-Port I/O Module

The Passport 8148TX module provides 48 autonegotiating 10/100 Mb/s ports

(Figure 1-5). Each port can operate in full- or half-duplex mode. Autonegotiation circuitry automatically negotiates the highest possible data rate and the duplex operation possible with the attached device, if the attached device supports IEEE 802.3u autonegotiation.

The port connectors are modular RJ-45 connectors with MDI-X wiring. This port can be connected to an MDI port (for example, a workstation or server) using a straight-through cable.

The Passport 8108TX module uses 10BASE-T/100BASE-TX RJ-45 port connectors to connect to 10 Mb/s or 100 Mb/s Ethernet segments or nodes.

Note: For 10 Mb/s connections, you can use Category 3, 4, or 5 copper unshielded twisted pair (UTP) cable. Use only Category 5 UTP cable to connect ports that will operate at 100 Mb/s.

Refer to Appendix A, “Technical Specifications,” for more information about the RJ-45 port connectors.
