DIP Switches
The DIP switches change port configuration within 2 seconds of being set.
To work in auto-negotiation mode,
A/M
must be set to
UP.
The rate and
duplex mode settings are not relevant.
In order to work in forced mode,
A/M
(AutoNeg/Manual) must be set to
DOWN.
The
F/H
(Duplex) and
10/100
(Rate) modes must be pre-set.
Half / Full Duplex Operation
Each port of the NH 210 is capable of supporting half/full duplex operation.
Port configuration is done through DIP switches only. Each group of four
10Mbps ports is controlled by its own DIP switch; i.e. ports 3-6 will all oper-
ate in the same duplex mode, as will ports 7-10. Each Fast Ethernet port has
its own set of DIP switches for setting duplex mode, auto-negotiation/manual
mode, and rate.
