Rear Panel
The rear panel of the NH 210, housing the power connection, is illustrated in
Figure 4. All fan holes MUST be kept unobstructed.
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.
