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). It also provides functionality to
read and write configuration and error log information to FRU error
log devices.
The RMC performs monitoring and control functions to ensure the successful
operation of the system.
•
Monitors thermal sensors on the CPUs, the PCI backplane, and the power
supplies
•
Monitors voltages, power supplies, and fans
•
Handles hot swap of power supplies and fans
•
Controls the operator control panel (OCP) display and writes status
messages on the display
•
Detects alert conditions such as excessive temperature, fan failure, and
power supply failure. On detection, RMC displays messages on the OCP,
pages an operator, and sends an interrupt 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:
The temperature reaches the failure limit.
The cover to the system card cage is removed.
The main fan (Fan 6) and the redundant fan (Fan 5) fail.
•
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 the DPR so that this information can be
accessed by the system.
•
Retrieves information from the DPR and stores it in FRU EEROMs.
