96 Advanced Configuration of the iDRAC6
Connecting the DB-9 or Null Modem Cable for the
Serial Console
To access the managed system using a serial text console, connect a DB-9 null
modem cable to the COM port on the managed system. In order for the
connection to work with the NULL modem cable, the corresponding serial
communications settings should be made in the CMOS setup. 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 5-5.
NOTE: The DB-9 cable can also be used for BIOS text console redirection.
Configuring the Management Station Terminal
Emulation Software
Your iDRAC6 supports a serial or telnet text console from a management
station running one of the following types of terminal emulation software:
• Linux Minicom in an Xterm

• Linux Telnet in an Xterm
• Microsoft Telnet
Perform the steps in the following subsections to configure your type of terminal
software. If you are using Microsoft Telnet, configuration is not required.
