Network Configurations

C.1

Overview

This appendix describes possible Ethernet configurations using one or more terminal servers.

C.2

Ethernet Configuration Rules

The MAXserver 1600/1608 terminal servers support the Ethernet configuration rules for multiport

transceivers.  On networks with an Ethernet backbone, there must be no more than one multiport

transceiver between the MAXserver 1600/1608 and the backbone, as shown in Figure C-1:

Multiport Transceiver

Figure C-1.  Valid Multiport Transceiver Configuration on Ethernet Backbone

Two multiport transceivers can be linked (cascaded) together in a standalone network that has no Ethernet

backbone, as shown in Figure C-2:
