Installing an MDA
The Uplink Module slot on the BayStack 450 switch accommodates 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 slot:
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.
