ASMi-31Installation and Operation ManualAppendix A. Ethernet Interface

LAN Installation	For 10BaseT installation, either a straight cable or a cross-cable may be
	required. Use a cross-cable when connecting to a port that does not
	implement the crossover function internally. Otherwise, use a straight cable.

Note

Switch Settings

Hubs usually implement the crossover function internally while NICs and other devices do not.

Set switches according to Table A-2.

Table A-2 DIP Switches Settings

Switch	Name	Description	Default
Number			Setting
1	SQ/FD	ON: Ethernet full-duplex mode	OFF
		OFF: Ethernet half-duplex mode
2	CMP	ON: Strips padding bits inserted in 64-byte frame	ON
		OFF: Transmits frames over WAN as is
3	FIL	ON: Passes only frames destined for another LAN	ON
		OFF: Disables LAN filter; passes all frames transparently
4	(nc)		OFF

Note

LED Indicators

The SQ/FD switch is not used in the Ethernet bridge with the BNC connector option.

Table A-3lists the IR-ETH LED indicators and describes their functions.
