10BASE-T/100BASE-TX MDAs

This section describes three 10BASE-T/100BASE-TX

MDA models. The three models can support various

product lines (see Table 2 on page 2 for a complete list of

supported product lines). For installation instructions, see

“Installing an MDA” on page 35.

The three 10BASE-T/100BASE-TX MDA models are:

• 400-4TX MDA

Not supported on the Business Policy Switch or

Passport 8132.

• 8100-4TX MDA

Supports BayStack 350/450/410 and Passport 8132.

• BPS2000-4TX MDA

Supports the Business Policy Switch.

The three models each use four 10BASE-T/100BASE-TX

RJ-45 (8-pin modular) connectors, that are configured as

media dependent interface-crossover (MDI-X) connectors.

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.

Note:

The MDAs are

not

hot-swappable. Power down

the BayStack switch or disconnect the Passport 8132

module from the switch backplane before installing or

removing an MDA.
