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. Power down the BayStack switch or disconnect the Accelar module from the switch backplane before installing or removing an MDA.

To install an MDA into the Uplink Module slots:

1.Unplug the AC power cord from the back of the switch.

2.Loosen the thumb screws and remove the filler panel (or previously installed MDA) from the Uplink Module slot.

Note: If you are replacing an installed MDA with another type of MDA, see “Replacing an MDA with a Different Model” on page 24.

3.Insert the MDA into the Uplink Module card guides (Figure 6).

Make sure the MDA slides in on the card guides. Failure to align the MDA to the card guides could damage the pins.
