The optional expansion slot can be used for a 10/100BASE-TX MDA that 
supports autonegotiation for either 10 Mb/s or 100 Mb/s operation, depending on 
the connecting device. For more information about autonegotiation, see 

The MDA, shown in 

, provides one 10/100 Mb/s port and its associated 

LEDs. The LED indicators are described in 

capable of operating at 100 Mb/s, Bay Networks recommends that only Category 
5 UTP cabling be used for connections to the RJ-45 port connector (see 

 

on 

 for RJ-45 pin assignments). 

The 10/100BASE-TX port also supports operation in full- and half-duplex mode. 
In full-duplex mode, the aggregate transfer can be either 20 Mb/s or 
200 Mb/s (for simultaneous transmit and receive at 100 Mb/s each) depending on 
the speed of the connecting device. In half-duplex mode, the transfer speed is 
either 10 Mb/s or 100 Mb/s (transmit or receive).
