Connecting The Db-9 Cable; Required Pinout For Db-9 Null Modem Cable - Dell Remote Access Controller 4 Firmware Version 1.30 User Manual

The telnet and SSH consoles are available on the DRAC 4 through the DRAC 4 NIC. Up to four
telnet client systems and one SSH client may connect at any given time.
The management station connection to the managed system serial or telnet console requires the
use of management station terminal emulation software (see "Configuring the Management
Station Terminal Emulation Software" for more information).
The following subsections explain how to connect your management station to the managed
system through a managed system external serial port using terminal software and a null modem
cable, or by telnet using terminal software through the managed system DRAC 4 NIC.

Connecting the DB-9 Cable

If you want to connect to the managed system using a serial text console, you must connect a
DB-9 null modem cable to the COM port that you are using on the managed system. Not all
DB-9 cables carry the pinout/signals necessary for this connection. The DB-9 cable for this
connection must conform to the specification shown in Table 3-4.
NOTE:
You can also use this cable for BIOS text console redirection with the DRAC 4 serial console disabled.
