1000BASE-X MDAs

The following are the 1000BASE-FX MDAs.

For a complete list of MDAs, see Table 1 on page 4. For

installation instructions, see “Installing an MDA” on page 24.

Shortwave Gigabit MDAs

The following 1000BASE-SX MDAs conform to the IEEE

802.3z 1000BASE-SX standard and use shortwave 850 nm fiber

optic connectors to connect devices over multimode (550 m/1805

ft.) fiber optic cable.

• 450-1SR MDA—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.

• 450-1SX MDA—single PHY MDA.

Figure 7 on page 17 shows the 450-1SR MDA and the 450-1SX

MDA front panels.
