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