Software Specifications
2.1
Red Hat* Embedded Debug and Bootstrap (Redboot)
Upon initial power on, the CMM enters into the Redboot firmware to bootstrap the embedded
environment. Upon execution, Redboot acts as a TFTP server and checks for a TFTP connection to
a client. If a TFTP connection exists, Redboot will accept a firmware update that is pushed down
from the client, check the firmware update for data integrity, and then write the update to the flash.
Note: Firmware updates using the Redboot TFTP method are supported for backwards compatibility.
However, updating from within the OS using the CLI is the preferred method of updating CMM
firmware. For information on the firmware update process refer to
Software" on page
Under normal circumstances, Redboot runs through the standard diagnostics, memory setup,
decompresses the OS kernel, and boots into that kernel.

Operating System
The CMM runs a customized version of embedded BlueCat
processor with Intel

2.3
Command Line Interface (CLI)
The Command Line Interface (CLI) connects to and communicates with the intelligent
management devices of the chassis, boards, and the CMM itself. The CLI is an IPMI-based library
of commands that can be accessed directly or through a higher-level management application.
Administrators can access the CLI through Telnet, SSH, or the CMM's serial port. Using the CLI,
users can access information about the current state of the system including current sensor values,
threshold settings, recent events, and overall chassis health, access and modify shelf and CMM
configurations, set fan speeds, perform actions on a FRU, etc. The CLI is covered in
"The Command Line Interface (CLI)" on page
2.4
SNMP/UDP
The chassis management module supports both queries and traps on SNMP (Simple Network
Management Protocol) v1 or v3. The SNMP version can be configured through the CLI interface.
The default is for SNMP v1. A MIB for the entire platform is included with the CMM. The CMM
can send out SNMP traps to up to five trap receivers.
Along with SNMP traps, the CMM sends UDP (User Datagram Protocol) alerts to port 10000. The
content of these UDP alerts is the same as the SNMP traps. SNMP is covered in
"SNMP" on page
