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.

Warning: Fiber optic equipment can emit laser  
or infrared light that can injure your eyes. Never  
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  
Anschlußteil. Gehen Sie stets davon aus, daß das  
Glasfaserkabel an eine Lichtquelle angeschlossen  
ist.

Avertissement: Léquipement 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.

There are four 100BASE-FX MDA models:  
400-2FX MDA  
Not supported on the Accelar Series Modules (see  
Table 2 on page 2)  
8100-2FX MDA  
Supports BayStack 350/450, BayStack 410, and  
Accelar Series Modules (see Table 2 on page 2)  
The 400-2FX MDA and the 8100-2FX MDA (Figure 2)  
each use two longwave 1300 nm SC connectors to attach  
devices over 62.5/125 micron multimode fiber optic cable.  
400-4FX MDA  
Not supported on the Accelar Series Modules (see  
Table 2 on page 2)  
8100-4FX MDA  
Supports BayStack 350/450, BayStack 410, and  
Accelar Series Modules (see Table 2 on page 2)  
The 400-4FX MDA and the 8100-4FX MDA (Figure 3)  
each use four longwave 1300 nm MT-RJ connectors to  
attach devices over 62.5/125 micron multimode fiber optic  
cable.  
The 100BASE-FX MDA models conform to the IEEE  
802.3u 100BASE-FX standard and can be used to attach  
fiber-based 100 Mb/s connections to other compatible Fast  
Ethernet devices. Single-mode fiber cable is not supported.

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

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:  
Reference Note: Gigabit Ethernet Physical Layer  
(Nortel Networks part number 201540-B)
