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.

If you connect to another Ethernet hub or Ethernet switch,
you need a crossover cable unless an MDI connection
exists on the associated port of the attached device.

Shortwave Gigabit Models
The two 1000BASE-SX (shortwave gigabit) MDA models
are:
•
450-1SR MDA -- single MAC MDA with a separate
redundant Phy (backup Phy port). Only one Phy port
can be active at any time. If the active Phy port fails,
the redundant Phy port automatically becomes the
active port.
•
450-1SX MDA -- single PHY MDA.
Both models conform to the IEEE 802.3z 1000BASE-SX
standard and use shortwave 850 nm fiber optic connectors
to connect devices over multimode (550 m/1805 ft) fiber
optic cable.

1000BASE-LX Multimode Applications
For 1000BASE-LX multimode applications, the longwave
gigabit transceivers must be mode conditioned externally
via a special offset SMF/MMF patch cord. The offset
SMF/MMF patch cord allows the same transceiver to be
used for both multimode and single-mode fiber. See your
Nortel Networks sales representative for more information
about the SMF/MMF patch cord.
The 1000BASE-LX transceiver is designed to
mechanically accommodate the single-mode ferrules used
on one end of the special offset SMF/MMF patch cord.
Multimode ferrules must not be used because they can
bind and cause damage to the transceiver. Do not connect
multimode cables directly into the 1000BASE-LX MDA
transceiver. Instead, connect a special offset SMF/MMF
patch cord into the transceiver, and then connect the
multimode cable into the SMF/MMF patch cord.
For more information about gigabit transmission over fiber
optic cable and mode conditioning, refer to the following
publication:
Reference Note: Gigabit Ethernet Physical Layer
Considerations (Nortel Networks part number 201540-B)
