Radio Frequency Notice
Note: This equipment has been tested and found to comply with the limits for a
Class A digital device, pursuant to Part 15 of the FCC rules. These limits are
designed to provide reasonable protection against harmful interference when the
equipment is operated in a commercial environment. This equipment generates,
uses, and can radiate radio frequency energy. If it is not installed and used in
accordance with the instruction manual, it may cause harmful interference to radio
communications. Operation of this equipment in a residential area is likely to cause
harmful interference, in which case users will be required to take whatever
measures may be necessary to correct the interference at their own expense.

This is to certify that the Nortel Networks MDAs are shielded against the generation
of radio interference in accordance with the application of Council Directive 89/
336/EEC, Article 4a. Conformity is declared by the application of EN 55 022 Class
A (CISPR 22).
Warning: This device is a Class A product. In a domestic environment, this product
may cause radio interference, in which case, the user may be required to take
appropriate measures.

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.

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

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.

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 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 f iber cable is not suppo rted.

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
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
Differe n t 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.

6. Attach devices to the MDA ports.
Refer to your device user guide for instructions on
attaching devices to the MDA ports.

After connecting the port cables, follow the instructions in
that guide to connect power and verify the installation

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 Netw orks

1000BASE-LX Multimode Applications
For 1000BASE-LX multimode applications, the longwave
gigabit transceivers must be mode conditioned
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
single-mode ferrules
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
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.

optic cable and mode conditioning, refer to the following
