H Using the Guardian Service Processor (GSP)
This section describes the Guardian Service Processor (GSP) commands and functions. The Guardian Service
Processor is an independent support processor built into the N and A class Core I/O card for the system
console that provides some major system manageability features
• Always-on capability: The GSP is alive if the power cord is plugged in.
• User/password access control: Supports operator and administrator users
• Multiple access methods to the GSP:
Local Port — use terminal or laptop computer for direct connect
Remote/modem Port — use dedicated modem RS-232 port and external modem
LAN — use telnet to access GSP LAN port from anywhere
• Mirrored console: the system console output stream is reflected to all of the connected console users
• Display and/or logging of:
The system console, System event logs (chassis codes), Virtual Front Panel (VFP), and system power and
configuration status.
• On local and modem ports, an independent, non-mirrored session can be started, either to connect to a
GSP, or login to the OS (SE).
• The GSP provides power control, system reset, and Transfer Of Control (TOC) capabilities.
