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.
Connecting to the Out-of-Band Management Port
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.
Cable Function Cable Type or Cable Solution
Connect a modem to the
MANAGEMENT port. Connect one end of a straight-through,
TIA/EIA- 232 modem cable to the
MANAGEMENT port and the other end to the
modem.
Connect a PC or other DTE
device to the
MANAGEMENT port. Connect one end of a crossover, TIA/EIA-232
cable to the MANAGEMENT port and the other
end to the PC or DTE device
or
attach a null-modem adapter to the
MANAGEMENT port. Then, attach a straight-
through modem cable to the null-modem
adapter.
