Mount the server into a rack or cabinet. See Installing the Servers in a Rack for both the 1U and 2U servers. Or, if you ordered the express rail rackmounting kit, which has the same rack rail assemblies for both servers, see Installing the Servers in a Rack With Express Rails.
Note - In the rest of this manual, the term rack means either an open rack or a closed cabinet.
Connect the server to a serial terminal or a terminal emulator (PC or workstation) to display system messages. See Powering On the System for the First Time.
Tip - The serial terminal or a terminal emulator should be connected before you connect the power cables. As soon as AC power is connected to the system, the service processor immediately powers on and runs diagnostics. Diagnostic test failures will be printed on the serial terminal. For more information, refer to the Oracle Integrated Lights Out Manager 3.x Supplement for SPARC Enterprise T5120 and T5220 Servers.
Connect the data cables to the server, but do not connect the AC power cable yet. See Connecting the Server Cables for Both Servers.
Connect the AC power cable to the server and examine the display for any error messages. See Powering On the System for the First Time.
Caution - There is a potential for electric shock if the server and related equipment are not properly grounded.
