Bandwidth Considerations when Daisychaining

Each cradle added to the daisychain impacts the bandwidth provided to the inserted EDAs, particularly when
the EDAs attempt to send and receive at data rates that exceed the bandwidth provided to the chain (typically
100 Mbps). If an EDA in a daisychained cradle does not use its bandwidth, that bandwidth is allocated to other
inserted EDAs.

Table 2-2

shows available bandwidth, based on 100 Mpbs, for the maximum number of daisychained cradles,

with each attempting transmission at the maximum data rate.

Ethernet Cradle Drivers

The MC70 includes Ethernet cradle drivers that initiate automatically when you place the EDA in a properly
connected Four Slot Ethernet cradle. After inserting the EDA, configure the Ethernet connection:
