Standby Phase The standby phase can be reached in two ways: 1. With the server OFF and power connected (the normal path), recognized by OK in the LCD display. 2. With the server ON after an operating system fault, recognized by STBY or an 8-digit code in the LCD display. In the Standby phase, the SP takes care of some automatic duties and is available for menus operation. The SP remains in the standby phase until a power-on request is detected. The Standby phase components are: Modem Configuration SP will configure the modem (if installed) so that incoming calls may be received, or outgoing calls may be placed. Dial In Monitor incoming phone line to answer calls, prompt for a password, verify the password and remotely display the standby menu. The remote session can be mirrored on the local ASCII console if the server is so equipped and the user enables this function. Menus The SP menus are password protected. Before you can access them you need to know either General User (Power-On Password or POP) or Privileged User (Privileged Access Password or PAP). Bring-Up Phase This phase is entered upon power-on, and exited upon loading of the operating system. The Bring-up phase components are: Retry Request Check The SP will check to see if the previous IPL attempt failed.
