IBM 150 Manual De Usuario

This chapter gives you an overview of the functionality of the Service 
Processor (SP) and how to use the SP. The SP is currently available on the 
Model 260, but not the Model 150.

The Service Processor is a hardware component that is imbedded onto the 
I/O planar of the Model 260. 

The SP has the capability to control the system NVRAM and real time clock 
interface. The SP card has a interface to assist with the bring-up and testing 
of complex processor systems. In addition, the SP has the capability to take 
over either S1 or S2 serial ports on the I/O planar. 

The SP card can use S1 or S2 to make a call home through an externally 
attached modem when it detects one of the following conditions:

  • System firmware surveillance failure

  • Operating system surveillance failure

  • Critical environmental failures

  • Restarts

The SP also has the capability to answer modem calls and generate a host 
interface to an external caller. The host functions of the SP card are 
contained in flash memory, resident on the SP card. The host modes are 
password protected and feature many levels of menus with support for 
several languages. 

Machine diagnostics can be launched from the host session, allowing you to 
remotely diagnose the status of the server. Almost all of this function is 
available even if the main processor is completely dead. The SP provides an 
immediate means to diagnose, check status, and sense the operational 
conditions of a remote server.

The Model 260 can also be booted remotely, and a remote user may enter the 
Systems Management Services (SMS) screens (only in ASCII mode).
