Introduction This guide describes and provides installation instructions for Nortel Networks* media dependent adapters (MDAs). It contains the following topics: • “Supported interfaces and products,” next • “MDA descriptions” on page 4 • “Installing an MDA” on page 24 • “Replacing an installed MDA” on page 27 • “Installing a GBIC in an MDA” on page 28 • “Removing an Installed GBIC from an MDA” on page 29 • “1000BASE-LX Multimode Applications” on page 30 Caution: MDAs are not hot-swappable.
Supported interfaces and products Table 1 shows the interface types used with the MDAs described in this guide.
• “GBIC MDA” on page 22 10BASE-T/100BASE-TX MDAs The 10BASE-T/100BASE-TX MDAs use four RJ-45 (8-pin modular) connectors, configured as media dependent interfacecrossover (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.

GBIC MDA The 450-1GBIC MDA (Figure 9) has a single Host port for Gigabit Interface Converters (GBICs). GBICs are hot-swappable input/output enhancement components that link Gigabit Ethernet ports with fiber optic networks. For more information about GBICs, see the publication Installing Gigabit Interface Converters (GBICs), part number 312865-A. For instructions on installing the 450-1GBIC MDA in a network device, see “Installing an MDA” on page 24.

The Uplink/Expansion Module slot on supported switches accommodates a single MDA using the following connectors. Table 12 MDA cable connectors MDA RJ45 UTP 10/100BASE-TX, page 5 SC fiber MT-RJ fiber X 100BASE-FX, page 9 X X 1000BASE-SX, page 16 1000BASE-LX, page 16 GBIC MDA, page 22 X Caution: MDAs are not hot-swappable. To avoid damage to the switch or MDA, power down the switch or disconnect the switch module from the switch backplane before installing or removing an MDA.

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 Plug the AC power cord into the back of the switch, or plug the switch module into the switch backplane. 7 Attach devices to the MDA ports.
For instructions on attaching devices to the MDA ports, refer to the publication for your switch. After connecting the port cables, follow the instructions 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 installed MDA To replace an installed MDA: 1 Unplug the AC power cord from the back of the switch, or unplug the switch module from the switch backplane.
Installing a GBIC in an MDA Before installing a GBIC, see “GBIC MDA” on page 22 for specific information about your MDA. The 450-1GBIC MDA Host port is covered with a spring-loaded filler panel that rotates out of the way as you push the GBIC into place. You can install or replace a GBIC in an operating 4501GBIC MDA without turning off power to the switch. Caution: Although GBICs are hot-swappable, MDAs are not.
Figure 11 Installing a GBIC 3 Press on the front of the GBIC until it snaps into place. 4 Remove the rubber plug to connect cables. Removing an Installed GBIC from an MDA For a description of the GBIC MDA, see “GBIC MDA” on page 22. To remove an installed GBIC: Do one of the following: • If the GBIC has spring tabs (Figure 9 on page 23), press in on the tabs on each side of the GBIC as you pull the GBIC out of the MDA’s Host port (Figure 12).
Figure 12 Removing a GBIC with spring tabs • If the GBIC has an extractor handle (Figure 9 on page 23), grasp the handle and pull firmly to remove the GBIC from the MDA’s Host port. 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. With the offset SMF/MMF patch cord, you can use the same transceiver for both multimode and single-mode fiber.
