62 Configuring and Using the DRAC 5 Command LIne Console
The serial console is available on the DRAC 5 through the managed system external serial connector.
Only one serial client system (management station) may be active at any given time. The telnet and SSH
consoles are available on the DRAC 5 through the DRAC modes (see "DRAC Modes"). Up to four telnet
client systems and four SSH clients may connect at any given time. The management station connection
to the managed system serial or telnet console requires 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
using the following methods:
• A managed system external serial port using terminal software and a null modem cable
• A telnet connection using terminal software through the managed system DRAC 5 NIC or the shared,
teamed NIC
Connecting the DB-9 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. 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 3-9.
NOTE: The DB-9 cable can also be used for BIOS text console redirection.
