Never look into an optical fiber or connector port. Always assume that the fiber optic cable or connector is connected to a laser light source. Vorsicht: Dieses Laser/LED-Produkt der Klasse 1 enthält eine Laserlichtquelle, die zu Augenverletzungen führen kann. Sehen Sie nie in einen Lichtwellenleiter oder Glasfaserstecker-Port.
302403-C.mkr Page 13 Monday, May 24, 1999 4:30 PM Avvertenza: Questo è un produtto laser/LED di Classe 1 e contiene una sorgente luminosa a laser che può danneggiare gli occhi. Non guardare mai all’interno di una port a fibra ottica o di una porta connettore. Dare sempre per scontato che il cavo di fibra ottica o il connettore siano collegati ad una sorgente luminosa a laser.
302403-C.mkr Page 14 Monday, May 24, 1999 4:30 PM There are two 1000BASE-SX (shortwave gigabit) MDA models (Figure 4): 1 450-1SR MDA (1-port redundant) 1000BASE-SX 2 1000BASE-SX Link Phy Select Activity TX RX TX RX 450-1SR MDA 3 4 1 450-1SX MDA (single port) 2 1000BASE-SX Link Phy Activity TX RX 450-1SX MDA 3 4 BS45044A Figure 4.
302403-C.mkr Page 15 Monday, May 24, 1999 4:30 PM • 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.

302403-C.mkr Page 22 Monday, May 24, 1999 4:30 PM 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.

Installing an MDA 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.
302403-C.mkr Page 24 Monday, May 24, 1999 4:30 PM 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.
302403-C.mkr Page 25 Monday, May 24, 1999 4:30 PM 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.
