1 Verify that the RAID controller module port link status LED and the
RAID controller module status LED are solid green for each port that is
connected to a cable. If the LEDs are not solid green, see "Planning: RAID

you selected.
3 Turn off the server, storage array, and expansion enclosures.

array and the server.
5 Turn on the expansion arrays and then the storage array and wait until the
system is fully booted.

7 Check the link status LED. If the link status LED is not green, replace the
cables.
If the problem is not resolved, see "Getting Help" on page 265.

NOTE: You must turn off the host server before resetting the cables on
the storage array or expansion enclosure.
