Can ping the advanced management module but cannot access it

If you cannot establish network connectivity to the advanced management module (through Telnet, SSH, or the Web browser), but you can ping the advanced management module, the problem is typically related to firmware or configuration.


You are unable to establish any login services to the advanced management module (through Telnet, SSH, or the Web browser), but you can ping it.


Perform these steps to resolve the problem:
  1. Ensure that a supported Web browser is being used.
    The advanced management module supports the following Web browsers for remote (client) access:
    • Microsoft Internet Explorer 5.5 or later (with latest Service Pack installed)
    • Mozilla Firefox version 1.07 or later
    The client Web browser that you use must be Java-enabled, must support JavaScript version 1.2 or later, and must have the Java Virtual Machine (JVM) Plug-in version 1.4.2_08 or later. The JVM Plug-in is available at
  2. Connect to the serial port on the advanced management module and attempt to log in. For more information about the serial port (including the pinout for the serial port), see Advanced management module input and output connectors.
  3. If possible, verify whether the advanced management module is running the network servers on their default network ports. If you cannot log in at all, check with the administrator for the BladeCenter S system.
    If you are connected through the serial port, use the ports command to ensure that all interfaces are enabled and the TCP ports are correct. For example,
                               ports -T system:mm[1]

    For information about using this command, see the Advanced Management Module Command-Line Interface Reference Guide .

  4. Verify whether this client workstation can connect to other advanced management modules. If it cannot, the problem is most likely due to a firewall running on the client workstation or the network. Shutdown any firewalls on the client workstation and try again. If the client workstation still has problems connecting to multiple advanced management modules, consult the network administrator for the LAN.
  5. Connect a laptop (that is known to be able to connect to other advanced management modules) to the advanced management module through the Ethernet port. Verify that the Ethernet link is up and that the laptop is configured so that it is on the same IP subnet as the advanced management module.
  6. If you can ping the advanced management module, attempt to log in to the advanced management module Web interface using a supported Web browser. If you can, suspect a problem in the network. Contact the network administrator for assistance.
  7. Reset the advanced management module to the default configuration, which will restore the default user ID and password:
    Important: Resetting the advanced management module will shut down the external ports for all I/O modules, which will disrupt all network and fibre connectivity. After the advanced management module resets with the default configuration, it will attempt to obtain a DHCP address for two minutes before using the default IP address ( and subnet mask ( Remove the Ethernet cable from the advanced management module if you do not want it to attempt to obtain a DHCP address.

    If you previously saved your configuration, you will be able to restore it after resolving the problem with the advanced management module. For more information about restoring a previously saved configuration, see the Advanced Management Module User's Guide.

    1. Insert a paper clip into the pin hole on the back of the advanced management module.
    2. Push the paper clip in all the way and hold it for approximately 10 seconds. The advanced management module will reset and the fans will run at full speed, which is clearly audible.
    3. Remove the paper clip from the pin hole.
  8. If the problem persists, contact IBM support.
