This appendix contains cable pinout information for the following ports located on the back of the Challenge S server:
serial port
parallel port
Ethernet 10-BASE T port
ISDN (integrated services digital network) port
Ethernet AUI (access unit interface) port
keyboard port
mouse port
SCSI port (small computer system interface) port
 | Note: The figures in this chapter show the connector pin assignments, not the cable pin assignments. |
Table A-1 shows cable pinout assignments for the two serial ports.
