2.1 NETWORK REQUIREMENTS

When connecting a network segment to the MRXI, via a transceiver and

an AUI cable, the following network requirements must be met:

• The transceivers used to connect the MRXI meet Ethernet Version 2 or

IEEE 802.3 standards.

• The AUI cables connecting the MRXI to the transceivers on the

network match the transceiver type on the network segment, Ethernet
