20 • The 450-1LR 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 450-1LX MDA is a single Phy MDA. Both models conform to the IEEE 80...

22 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. To install an MDA into the Uplink Module slots: 1....

25 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. ...
