400-4TX MDA
Not supported on the Accelar Series Modules (see
Table 2 on page 2)
8100-4TX MDA
Supports BayStack 350/450, BayStack 410, and
Accelar Series Modules (see Table 2 on page 2)
Both models use four 10/100BASE-TX RJ-45 (8-pin
modular) port connectors to attach Ethernet devices.
The RJ-45 ports 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 are connecting
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 10/100BASE-TX MDA ports can operate at either 10
Mb/s or 100 Mb/s. The port speed is determined through
autonegotiation with its connecting device.
Table 3 describes the 10/100BASE-TX MDA components
and LEDs.

look into an optical fiber or connector port.
Always assume that fiber optic cables are
connected to a light source.
Vorsicht: Glasfaserkomponenten können
Laserlicht bzw. Infrarotlicht abstrahlen, wodurch
Ihre Augen geschädigt werden können. Schauen
Sie niemals in einen Glasfaser-LWL oder ein

Avertissement: L’équipement à fibre optique
peut émettre des rayons laser ou infrarouges qui
risquent d’entraîner des lésions oculaires. Ne
jamais regarder dans le port d’un connecteur ou
d’un câble à fibre optique. Toujours supposer que
les câbles à fibre optique sont raccordés à une
source lumineuse.
Advertencia: Los equipos de fibra óptica
pueden emitir radiaciones de láser o infrarrojas
que pueden dañar los ojos. No mire nunca en el
interior de una fibra óptica ni de un puerto de
conexión. Suponga siempre que los cables de fibra
óptica están conectados a una fuente luminosa.
Avvertenza: Le apparecchiature a fibre ottiche
emettono raggi laser o infrarossi che possono
risultare dannosi per gli occhi. Non guardare mai
direttamente le fibre ottiche o le porte di
collegamento. Tenere in considerazione il fatto
che i cavi a fibre ottiche sono collegati a una
sorgente luminosa.

The 450-1SR MDA is a 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.
The 450-1SX MDA is a 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 meter) fiber optic
cable.

port fails, the redundant Phy port automatically
becomes the active port.
The 450-1LX MDA is a single Phy MDA.
Both models conform to the IEEE 802.3z 1000BASE-LX
standard and use longwave 1300 nm fiber optic connectors
to connect devices over single mode
(3 kilometer) or multimode (550 meters) fiber optic cable.
Note: The optical performance of this transceiver
cannot be guaranteed when connected to a multimode
fiber plant without the use of the special offset
SMF/MMF mode conditioning patch cord (see
“1000BASE-LX Multimode Applications” on
page 25).

Installing an MDA
The Uplink Module slot on supported BayStack and
Accelar switches can accommodate a single MDA. The
connection can be either an RJ-45 10/100BASE-TX MDA
or a fiber (100BASE-FX or 1000BASE-SX/LX) MDA
with an SC or MT-RJ connector.
Note: The MDAs are not hot-swappable. Power down
the BayStack switch or disconnect the Accelar module
from the switch backplane before installing or
removing an MDA.
To install an MDA into the Uplink Module slots:
1. Unplug the AC power cord from the back of the
switch.
2. Loosen the thumb screws and remove the filler
panel (or previously installed MDA) from the
Uplink Module slot.
Note: If you are replacing an installed MDA with
another type of MDA, see “Replacing an MDA with a
Different Model” on page 24.
3. Insert the MDA into the Uplink Module card
guides (Figure 6).
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 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. Attach devices to the MDA ports.
Refer to your device user guide for instructions on
attaching devices to the MDA ports.
23
After connecting the port cables, follow the instructions in
that guide to connect 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 MDA with a Different Model
When replacing an installed MDA in a BayStack switch
with another type of MDA, clear the switch NVRAM:
1. Power down the switch.
Remove the AC power cord from the power source.
2. Remove the installed MDA.
Loosen the thumbscrews and remove the MDA.
3. Cycle the switch power.
Power up the switch and wait for the Nortel Networks
logo screen to appear (approximately 20 seconds);
then power down the switch.
4. Install the replacement MDA.
Be sure to tighten the two thumbscrews on the
firmly
MDA front panel.
5. Power up the switch.

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 accomodate the
used
single-mode ferrules
on one end of the special offset SMF/MMF patch cord.
must not be used because they can
Multimode ferrules
bind and cause damage to the transceiver. Do not connect
multimode cables into the 1000BASE-LX MDA
directly
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:
