Configuring NTP Settings on the InfiniBand-Ethernet Gateway Switch

After replacing the InfiniBand-Ethernet gateway switch, the NTP time source must be configured using the following procedure:

  1. Using a web browser on your workstation, enter 172.29.254.127 in the browser address bar to connect to the InfiniBand-Ethernet gateway switch. If a second InfiniBand-Ethernet gateway switch is present, enter 172.29.253.127.

  2. On the Setup tab, select the Date and Time option from the left column of the management console.

  3. Adjust the Time Zone field as appropriate.

    If the date and time is off by days, months, or years, adjust the values to the current date and time. If these fields are read-only, temporarily disable NTP so that you can adjust them. To temporarily disable NTP, do the following:

    1. Select the NTP option from the left column of the management console.

    2. Uncheck the Enable NTP Time Synchronization check box and click Apply.

    3. Select the Date and Time option from the left column of the management console.

    4. Adjust the Date and Time Zone fields as appropriate and click Apply.

  4. Select the NTP option from the left column of the management console.

  5. In the NTP Server and Peer Associations section, the first two nodes of each address should be the subnet of the FM LAN. By default this is 172.29, so if the client has not modified the FM LAN subnet, the two IP addresses should be 172.29.254.252 and 172.29.253.252 (if a second FMP is present). If a different subnet is being used for the FM LAN, use that instead of 172.29. If the IP addresses are not correct, perform the following steps:

    1. In the Add New NTP Server section, enter the following:

      • Server IP address: 172.29.254.252 (or x.y.254.252, where x.y is the customized subnet).

      • Version: 4 (default)

      • Enabled: Yes (default)

  6. Click Add NTP Server.

  7. If there is a second FMP in the system, in the Add New NTP Peer section, enter the following:

    • Server IP address: 172.29.253.252 (or x.y.253.252, where x.y is the customized subnet).

    • Version: 4 (default)

    • Enabled: Yes (default)

  8. Click Add NTP Peer.

  9. Check that the NTP Server and Peer Associations section contains the added NTP server and peer IP addresses.

  10. If incorrect IP addresses were configured, select the two check boxes to the left of those IP addresses and then click the Remove Association button.

  11. Select the Enable NTP Time Synchronization check box (if it's not already enabled) and then click Apply.

    Note: There might be a delay from the time NTP synchronization is enabled and the correct IP addresses are defined for the switch to synchronize with the NTP server, but eventually the InfiniBand-Ethernet gateway switch (in the Date and Time view) will show the same date and time as FMP1. If FMP1 is getting its clock from an NTP server, then the Reference Clock field will display the IP address of FMP1s’ source NTP server. Likewise, the FMP2 IP address will show FMP1 as its NTP source.

  12. Click the Save button in the top right corner. The final display should appear as follows.

  13. Repeat this procedure on the second InfiniBand-Ethernet gateway switch (if a second one is present).
