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.
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.
