02403-B.mkr Page 1 Friday, January 15, 1999 2:56 PM Introduction This document provides procedures for installing optional plug-in media dependent adapters (MDAs) into supported Bay Networks products equipped with an expansion slot. The MDAs can support high-speed connections to servers, shared Fast Ethernet hubs, or backbone devices. Note: The MDAs are not hot-swappable. Power down the switch before installing or removing an MDA.

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 400-4TX MDA can operate at either 10 Mb/s or 100 Mb/s. The speed is determined through autonegotiation with its connecting device. For installation instructions, see “Installing an MDA” on page 17.
302403-B.mkr Page 6 Friday, January 15, 1999 2:56 PM 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.
302403-B.mkr Page 7 Friday, January 15, 1999 2:56 PM 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.

302403-B.mkr Page 16 Friday, January 15, 1999 2:56 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 Bay Networks sales representative for more information about the SMF/MMF patch cord.
302403-B.mkr Page 17 Friday, January 15, 1999 2:56 PM Installing an MDA The Uplink Module slot on the BayStack 450 switches accommodates 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 MDA is not hot-swappable. Power down the switch before installing or removing an MDA. To install an MDA into the Uplink Module slot, follow these steps: 1. Unplug the AC power cord from the back of the switch. 2.
302403-B.mkr Page 18 Friday, January 15, 1999 2:56 PM 3. Insert the MDA into the chassis slot (see Figure 5) taking care to slide the MDA onto the guides provided on the chassis. Caution: Make sure the MDA slides in on the guides provided. Failure to align the guides could result in bent and broken pins BS45046B Figure 5. Installing an MDA 4. Press the MDA firmly into the chassis slot. Be sure that the MDA is fully seated into the mating connector. 5.
302403-B.mkr Page 19 Friday, January 15, 1999 2:56 PM After connecting the port cables, continue to follow the instructions in that manual 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 with another type of MDA, complete the following steps to clear the switch NVRAM: 1. Power down the switch.
