Appendix B. Cable and Pin Information

This appendix provides information on cables that can be used with the SmartStack STS16-20D/STS16-20R. It also provides minimum pin-out information to be used to verify that the cables are correctly wired.

Table 16 lists the type of cables that are used when connecting to the OBM port (labeled MANAGEMENT) on the front panel of the switch.

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.
