MDA descriptions
This section describes the following MDAs:

• “100BASE-FX MDAs” on page 9
• “1000BASE-X MDAs” on page 17
• “GBIC MDA” on page 23

• “BPS2000-1GT MDA” on page 27
• “BPS2000-2GT MDA” on page 29
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.

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 13).
Make sure the MDA slides in on the card guides. Failure to
align the MDA to the card guides could damage the pins.

4 Press the MDA firmly into the Uplink/Expansion Module
slot.
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.
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 23 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, see 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 14).

GBICs are keyed to prevent improper insertion. If the GBIC
resists pressure, do not force it. Remove it, turn it over, and
reinsert it.

4 Remove the rubber plug to connect cables.
Removing an Installed GBIC from an MDA
For a description of the GBIC MDA, see “GBIC MDA” on
page 23.
T o remove an installed GBIC:
Do one of the following :
• If the GBIC has spring tabs (Figure 9 on page 2 4), press in
on the tabs on each side of the GBIC as you pull th e GBIC
out of the MDA’s Host port (Figure 15).

• If the GBIC has an extractor handle (Figure 9 on page 24),
grasp the handle and pull firmly to remove the GBIC from
the MDA’s Host port.
Installing a Small Form Factor Pluggable (SFP) GBIC
This section lists the steps to install a SFP GBIC.
T o install a SFP GBIC:
1 Remove the SFP GBIC from its protective packaging.
2 Verify that the SFP GBIC is the correct model for your
network configur ation ().
3 Remove the dust cover from the SFP GBIC’s optical bores.
4 Grasp the SFP GBIC between your thumb and forefinger.
5 Insert the SFP GBIC into the slot on the front panel of the
Gigabit Ethernet swi tching module .

Removing a Small Form Factor (SFP) GBIC
This section lists the steps for removing a GBIC.
To remove a GBIC:
1 Disconnect the network fiber cable from the SF P GBIC
connector.
2 Depending on your SFP GBIC model, either pull the LC
extraction tab located in the front of the SFP GBIC (below
right) with your thu m b and forefinger, or press the button on
the bottom of the MT-RJ SFP GBIC (below left).

3 Slide th e SFP GBIC ou t of th e Gigabit Ethernet module slot.
4 If the SFP GBIC does not slide easily from the module slot,
use a gentle side-to-side rock ing motio n while firmly pu lling
the SFP GBIC from the slot.
5 Dispose of the SFP GBIC according to all national laws and
regulations.
Note: If you are storing a SFP GBIC, remember to place
a dust cover over the fiber optic bores.

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 offset SMF/MMF
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.
