Prior to powering on the server for the first time, make a serial connection to the SP from a terminal or terminal emulator. After making this serial connection, you will be able to view the system messages when you connect the power cords.
A null modem configuration is needed, meaning the transmit and receive signals are reversed (crossed over) for DTE to DTE communications. You can use the supplied RJ-45 crossover adapters with a standard RJ-45 cable to achieve the null modem configuration.
Note - If you power on the server for the first time and do not have a terminal or terminal emulator (PC or workstation) connected to the SER MGT port, you will not see system messages.
Configure the system for the first time through the SER MGT port. After the initial configuration, you can set up communication between the SP and host through this Ethernet interface.
When the power cords are connected, the SP initializes and the power supply LEDs illuminate. After a few minutes, the SP login prompt is displayed on the terminal device. At this time, the host is not initialized or powered on.
