Appendix B. Cable and Pin Information

This appendix provides information on cables that can be used with the SmartStack

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.
Cable Function

device to the
MANAGEMENT port.

Table 16. Connecting to the Management Port

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 and Pin Information
Cable Type or Cable Solution
Connect one end of a straight-through,
TIA/EIA- 232 modem cable to the
MANAGEMENT port and the other end to the
modem.
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.
