Operating instructions

6.1 RMC Overview
The remote management console provides a mechanism for monitoring
the system (voltages, temperatures, and fans) and manipulating it on a
low level (reset, power on/off, halt).
The RMC performs monitoring and control functions to ensure the successful
operation of the system.
• Monitors thermal sensors on the CPUs, the system motherboard, and the
power supplies
• Monitors voltages, power supplies, and fans
• Handles swapping of hot-plug power supplies and fans
• Controls the operator control panel (OCP) and status can be interpreted
from the OCP LEDs.
• Detects alert conditions such as excessive temperature, fan failure, and
power supply failure. On detection, pages an operator, and sends an inter-
rupt to SRM, which then passes the interrupt to the operating system or an
application.
• Shuts down the system if any fatal conditions exist. For example:
o The temperature reaches the failure limit.
o The cover to the system card cage is left off too long.
o Both system fans or any CPU fan fails.
• Retrieves and passes information about a system shutdown to SRM at the
next power-up. SRM displays a message regarding the last shutdown.
• Provides a command-line interface (CLI) for the user to control the system.
From the CLI you can power the system on and off, halt or reset the system,
and monitor the system environment.
• Passes error log information to shared RAM so that this information can be
accessed by the system.
