■ 8 bits
■ No parity
■ 1 stop bit
■ No handshaking
Serial devices that can communicate with the serial management port are:
■ Terminal server
■ TIP line connected to another Sun™ computer
■ Alphanumeric terminal or similar device
Because it is a serial connection, there is communication between only two devices.
This constraint limits access and provides for a more secure link between the
administrator and the server.
The serial management port is not a general-purpose serial port. It is dedicated to
the system controller. If you want to use a serial peripheral, connect it to the
standard 9-pin serial port on the back panel of the server. The Solaris OS sees this
port as TTYA and it is labeled as such.
Establishing Communication With the Serial
Management Port
▼ To Access The System Console Through a Terminal Server
1. Complete the physical connection from the serial management port to your
terminal server.
The serial management port on the server is a data terminal equipment (DTE) port.
Verify that the serial port pinouts of the server match those of the terminal server
you plan to use.
■ If the pinout of the server serial management port corresponds with the pinout of
the RJ-45 port on the terminal server, you have two connection options:
■ Connect a serial interface breakout cable directly to the server.
■ Connect a serial interface breakout cable to a patch panel and use the straight-
through patch cable (supplied by Sun) to connect the patch panel to the server.
■ If the pinout of the server serial management port do not correspond with the
pinout of the RJ-45 port on the terminal server, you need to make a crossover
cable.
TABLE 1-1 shows the pinout of the crossover cable.
