Chapter 7. Using the Service Processor
The service processor runs on its own power boundary and continually monitors hardware attributes and
the environmental conditions within the system. The service processor is controlled by firmware and does
not require the operating system to be operational to perform its tasks.
The service processor menus allow you to configure service processor options, as well as enable and
disable functions.
Service processor menus are available using an ASCII terminal when OK is displayed on the operator
panel or when the service processor has detected a system problem (such as a surveillance failure).
Service Processor Menus
The service processor menus are divided into the following groups:
v General user menu - the user must know the general-access password.
v Privileged user menus - the user must know the privileged-access password.
If the system is powered off, the service processor menus can be accessed locally or remotely on the
following:
v Serial port 1 (S1)
v Serial port 2 (S2)
Accessing the Service Processor Menus Locally
Service processor menus can be accessed by attaching an ASCII terminal to serial port 1 (S1) or serial
port 2 (S2). After OK displays in the operator panel, press any key on the keyboard to signal the service
processor.
When you gain access, the service processor prompts you for a password (if one is set), and when
verified, displays the service processor menus.
The service processor menu prompt, represented by 0> or 1>, indicates the serial port to which the
terminal is connected.
v An ASCII terminal can have the following prompts:
– 0> indicates serial port 1 (S1)
– 1> indicates serial port 2 (S2)
Accessing the Service Processor Menus Remotely
If your system has a modem connected to serial port 1 or serial port 2 and is configured for call-in (see
"Modem Configuration Menu" on page 212), the service processor menus can be accessed remotely as
follows:
1. With the system powered off, call in from a remote terminal.
2. The service processor detects ring-indicate and prompts you for a password (if one is set). When
verified, the service processor menus display remotely.
Saving and Restoring Service Processor Settings
All the settings that you make (except language) from the service processor menus can be backed up
either for recovering from a fault that may corrupt these settings, or for replicating these settings to other
servers that include a service processor.
