Using the Passport 8100 Modules

Passport 8132TX 32-Port I/O Module

The Passport 8132TX module (Figure 1-3) is a single-slot I/O module for the Passport 8000 Series chassis. It has 32 autosensing 10BASE-T/100BASE-TX switched ports with RJ-45 connectors. The ports have integrated LEDs to indicate port operation, and the module has three additional LEDs to indicate system operation. An expansion slot allows you to install an MDA to provide additional port types. You can add 10/100BASE-T, 100BASE-FX, or Gigabit Ethernet ports by installing an optional MDA in the Passport 8132TX module. Inserter/extractor levers and captive retaining screws are at each end of the module.

10BASE-T/100BASE-TX Port Connectors

The Passport 8132TX module provides 32 10/100 Mb/s autosensing ports that support the IEEE 802.3u autonegotiation standard. Each port can operate in full- or half-duplex mode. When a port is connected to another device that also supports the IEEE 802.3u standard, the two devices negotiate the best speed and duplex mode of operation.

The port connectors are 8-pin modular RJ-45 connectors configured as MDI-X (media-dependent interface-crossover) connections. You can connect these ports to an MDI port (for example, a workstation or server) using a straight-through cable. If you are connecting to a device that does not have an MDI port, use a crossover cable (see “MDI and MDI-X Connections” on page A-12).

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.
