Chassis Management Modules (CMMs)

Background

The Chassis Management Module (CMM) monitors and controls all hardware components in the Chassis.

The CMM communicates with a dedicated SGM using SNMP.

If a hardware sensor reports a problem, the CMM automatically takes action or sends a report.

CMMs have a Command Line Interface.

For more information, see the Quantum Scalable Chassis Getting Started Guide and sk93332.

Connecting to the Active CMM

Method

Instructions

Telnet, or SSH

  1. Open a Telnet or SSH session from one of the SGMs.

  2. Log in to the Expert mode.

  3. Connect to the CMM with this command:

    member CMM

  4. Enter admin for the user name and password.

Serial port

  1. Connect to the serial port on the front panel of the CMM.

  2. Open a console window in your terminal emulation program (for example, PuTTY, SecureCRT).

    Use the default serial connection parameters: 9600, 8, N, 1

  3. Enter admin for the user name and password.

Connecting to the Standby CMM

Step

Instructions

1

Connect to the command line on the Active CMM (see Connecting to the Active CMM).

2

At the command prompt, run:

ifconfig

3

Record the IP Address for the USB interface.

4

Open a Telnet or SSH session from the Active CMM to the Standby CMM with the IP address from the table below:

IP address of Active CMM

IP address of Standby CMM

192.168.1.130

192.168.1.131

192.168.1.131

192.168.1.130

192.168.1.2

Collecting the CMM Diagnostic Information (clia fruinfo)

Step

Instructions

1

Connect to the command line on the Active CMM (see Connecting to the Active CMM).

2

Configure your terminal emulation program (for example, PuTTY, SecureCRT) to save the log file for the current session.

3

Get the contents of the /etc/summary file:

cat /etc/summary

Note - This command can take several minutes to run.

4

Get the contents of the /tmp/debug.log file:

cat /tmp/debug.log

5

Get the contents of the /etc/shmm.cfg file:

cat /etc/shmm.cfg
