Unable to ping the Management | If the Management Card’s Status LED is green, try to ping another node on |
Card | the same network segment as the Management Card. If that fails, it is not a |
| problem with the Management Card. If the Status LED is not green, or if |
| the ping test succeeds, perform the following checks: |
| • Verify that the Management Card is properly seated in the UPS. |
| • Verify all network connections. |
| • Verify the IP addresses of the Management Card and the NMS. |
| • If the NMS is on a different physical network (or subnetwork) from the |
| Management Card, verify the IP address of the default gateway (or |
| router). |
| • Verify the number of subnet bits for the Management Card’s subnet mask. |

Cannot access the command line | • Make sure you are using the correct access method, Telnet or Secure SHell |

| Telnet is enabled. Enabling SSH automatically disables Telnet. |
| • For SSH, the Management Card may be creating a host key. The |
| Management Card can take up to one minute to create the host key, and |
| SSH is inaccessible for that time. |
|
|
Cannot access the Web interface | • Verify that HTTP or HTTPS access is enabled. |
| • Make sure you are specifying the correct URL — one that is consistent |
| with the security system used by the Management Card. SSL requires |
| https, not http, at the beginning of the URL. |
| • Verify that you can ping the Management Card. |
| • Verify that you are using a Web browser supported for the Management |
| Card. See “Supported Web browsers” on page 28. |
| • If the Management Card has just restarted and SSL security is being set |
| up, the Management Card may be generating a server certificate. The |
| Management Card can take up to one minute to create this certificate, and |
| the SSL server is not available during that time. |
