10BASE-T/100BASE-TX MDAs
The 10BASE-T/100BASE-TX MDAs use four RJ-45 (8-pin
modular) connectors, configu r ed as media dependent interfacecrossover (MDI-X) connectors. These ports connect over straight
cables to the network interface cont roller (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.
The following are the 10BASE-T/100BASE-TX MDAs.
• 400-4TX MDA, page 6
• 8100-4TX MDA, page 6

Caution: MDAs are not hot-swappable. To avoid
damage to the switch or MDA, power down the switch o r
disconnect the switch mo dule fro m th e switch backplane
before installing or removing an MDA.
T o install an MDA:
1 Unplug the AC power cord from the back of the switch, or
unplug the switch module from the switch backplane.
2 Loosen the thumb screws and remove the filler panel (or
previously installed MDA) from the Uplink/Expansion
Module slot.
3 Insert the MDA into the Uplink/Expansion Module card
guides (Figure 10).
Make sure the MDA slides in on the card guides. Failure to
align the MDA to the card guides could damage the pins.

Be sure that the MDA is fully seated into the mating
connector.
5 Secure the MDA by tightening the thumb screws on the
MDA front panel.
6 Plug the AC power cord into the back of the switch, or plug
the switch module into the switch backplane.
7 Attach devices to the MDA ports.
26
Page 29
For instructions on attaching devices to the MDA ports, refer
to the publication for your switch. After connecting the port
cables, follow the instructions to conn ect power and verify
the installation.
Note: The IEEE 802.3u specification requires that all
ports operating at 100 Mb/s use only Category 5
unshielded twisted pair (UTP) cabling.
Replacing an installed MDA
T o replac e an installed MDA:
1 Unplug the AC power cord from the back of the switch, or
unplug the switch module from the switch backplane.
2 Remove the installed MDA.
Loosen the two thumbscrews on the MDA front panel to
remove the MDA.
3 Install the replacement MDA.
Be sure to firmly tighten the two thumbscrews on the MDA
front panel.
4 Plug the AC power cord into the back of the switch, or plug
the switch module into the switch backplane.
5 Attach devices to the MDA ports.
For instructions on attaching devices to the MDA ports, refer
to the publication for your switch.

Installing a G B IC in a n MDA
Before installing a GBIC, see “GBIC MDA” on page 22 for
specific information about your M DA.
The 450-1GBIC MDA Host port is covered with a spring-loaded
filler panel that rotates out of th e way as you push th e GBIC int o
place. You can install or replace a GBIC in an operat ing 4501GBIC MDA without turning off power to the switch.
Caution: Although GBICs are hot-swappable, MDAs
are not. To avoid damage to the switch or MDA, power
down the switch or unplug the switch module before
installing or removing an MDA.
For more information about GBICs, se e the publication Installing
Gigabit Interface Converters (GBICs), part number 312865-A.
T o install a GBIC in an MDA:
1 Remove the GBIC from its protective packaging.
2 Insert the GBIC into the MDA Host port (Figure 11).
GBICs are keyed to prevent improper insertion. If the GBIC
resists pressure, do not force it. Remove it, turn it over, and
reinsert it.

1000BASE-LX Multimode Applications
For 1000BASE-LX multimode app lications, the longwave
gigabit transce ivers must be mode cond itioned externally via a
special offset SMF/MM F p atch c ord. With the of f set S MF /MM F
patch cord, you can use the same transceiver for both multimode
and single-mode fiber. For more information about the SMF/
MMF patch cord, see your Nortel Networks sales representative.
The 1000BASE-LX transceiver is des ig ned 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 dam a ge to the
transceiver. Do not connect multimode cables directly into the
1000BASE-LX MDA transceiver. Instead, connect a speci al
offset SMF/MMF patch cord into the transceiver, and then
connect the multimode cable into the SMF/MMF patch cord.
