Caution: Only qualified technicians should install this

equipment.

Place all printed circuit boards on an antistatic mat until you are ready to install them. If you do not have an antistatic mat, wear a discharge leash to free yourself of static before touching any of the printed circuit boards, or free yourself of static by touching a grounded metal object before handling a printed circuit board.

Product Safety

CSA 22.2 No. 950-M95/UL1950, 3rd ed. EN60950: 1992 /A1:1993 /A2:1993 /A3:1995 /A4: 199721CFR, Chapter I EN60825-1:1994 /A11:1996

Caution: 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.

Caution: 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 is

Caution: 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.

Caution: 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.

Caution: 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.

Required Tool

These procedures require a Phillips screwdriver #1.

Introduction

The Media Dependent Adapters (MDAs) for the Nortel* 8672ATM, 8672ATME, and 8672ATMM Modules are modular port adapters that you install on the module.

Each of these modules have two slots for MDAs. You can install up to two of the following MDAs:

• 1-port OC-12c/STM-4 (Figure 1)

• 4-port OC-3c/STM-1 (Figure 2)

• 2-port DS-3 (Figure 3)

Each MDA has ports for connection to an ATM network. You can mix types of MDAs to achieve flexibility in connectivity types.

Table 1 shows the available types of MDAs for the 8672ATM,

8672ATME, and 8672ATMM Modules.

Port type Model Cable type Connector type

OC-12c/STM-4 DS1304004 Multimode fiber Duplex SC

DS1304005 Single mode fiber Duplex SC

OC-3c/STM-1 DS1304006 Multimode fiber MT-RJ

DS1304007 Single mode fiber MT-RJ

DS-3 DS1304002 75 ohm coaxial BNC

Note: The OC-3c/STM-1 and OC-12c/STM-4 MDAs

support concatenated transmission.

The OC-3c/STM-1 and OC-12c/STM-4 MDAs for the 8672ATME and 8672ATMM Modules are class 1 laser products as identified by the label on the MDA (

Figure 4).
