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:
Ÿ
Modem Configuration
SP will configure the modem (if installed) so that incoming calls may be received,
or outgoing calls may be placed.
Ÿ
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.
Ÿ
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:
Ÿ
Retry Request Check
The SP will check to see if the previous IPL attempt failed. If two consecutive
fails are detected, the SP displays an error code and places an outgoing call to
notify an external party if the user has enabled this option.
Ÿ
Dial Out
E-2
