SmartStack STS16-20RM/STS16-20FRM Token Ring Switches, P/N: 9032957-01 Cable and Pin Information
Out-of-Band Management Port and Cable Pin-Outs
The switch’s Out-of-Band Management (OBM) port (labeled MANAGEMENT on
the front panel) is an TIA/EIA-232 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.
