Troubleshooting Enclosure Connections
1 Verify that the EMM port link status LED and the EMM status LED are
solid green for each port that is connected to a cable. If the LEDs are not
solid green, see "Enclosure Management Module" on page 13.
2 Ensure that all the cables are attached correctly according to enclosure
mode you selected. For more information about enclosure modes, see
"Operating Your Storage Enclosure" on page 19.
3 If you reseated cables, reboot the host server.
NOTE:
You must turn off the host server before reseating the cables on
the enclosure.
If the problem is not resolved, see "Getting Help" on page 57.
