Appendix A. Cable and PIN Information
A.1 Cable and Pin Information
This chapter includes minimum pin-out information and specifications for cables
that should be used with the switch.
Note: The most common cause of problems for LAN communications is incorrect
cabling. Therefore, Olicom recommends that you work with a qualified LAN cable
installer for assistance with your cabling requirements.
A.1.1 Out-of-Band Management Port and Cable Pin-Outs
The switch's Out-of-Band Management (OBM) port (labelled "Management" on
the front panel) is an EIA 232 DB-9 port wired as a DTE. For this reason, you
cannot use a straight-through modem cable to directly connect a terminal to the
Management port.
For a terminal connection, you can use either a null-modem cable or a modem
cable with a null-modem adapter attached. For a modem connection, you can use a
standard modem cable.
This section provides pin-out information for the cables you can use to connect to
the Management port.
