MDI-X to MDI-X Cable Connections
If you are connecting the BayStack 410-24T switch to a device that also
implements MDI-X ports, use a crossover cable (Figure 5-3
).

DB-9 (RS-232-D) Console/Comm Port Connector
The DB-9 Console/Comm Port connector (Figure 5-4) is configured as a data
communications equipment (DCE) connector. The DSR and CTS signal outputs
are always asserted; the CD, DTR, RTS, and RI signal inputs are not used. This
configuration enables a management station (a PC or console terminal) to connect
directly to the switch using a straight-through cable.
