84 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" on page 225).
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" on page 85 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.
