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.

Uplink/Expansion Module 1 = Card guides 2 = Uplink module slot 3 = BayStack or Accelar switch Figure 6. Installing an MDA Press the MDA firmly into the Uplink Module slot. Be sure that the MDA is fully seated into the mating connector.
Remove the installed MDA. Loosen the thumbscrews and remove the MDA. Cycle the switch power. Power up the switch and wait for the Nortel Networks logo screen to appear (approximately 20 seconds); then power down the switch. Install the replacement MDA.
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 used on one end of the special offset SMF/MMF patch cord.
