Opening the DXi6902
Node
Note: You do not need to remove the Node from the rack to remove
and replace internal components. Using the DXi6902 sliding
rail system, you can pull the Node out on the sliding rails until
you have enough space to remove the Node chassis top and
access the internal components. IMPORTANT: If you leave the
Node in the rack, you still must disconnect both power cables
from the Node prior to opening the Node cover.
To remove the DXi6902 Node from the rack and remove the top cover:
1 Shut down the DXi6902 Node (see Turning On and Shutting Down
the System on page 21).
2 If installed, remove the front bezel from the Node by lifting the latch
on the left side of the bezel.
3 Remove all power, SAS, Ethernet, and Fibre Channel cables from the
rear of the Node. Make sure to label the cables so they can be easily
identified when they are re-connected to the Node after the
replacement procedure is complete.
4 Press the locking tab on either side of the Node, and pull the Node
out from the rack until the inner rails lock.
Caution: Do not use excessive force when pulling the chassis
forward to fully extend the Node or Expansion Module
in the rack rails. Using excessive force could bypass the
slide rail stop mechanism.
Note:
If necessary, remove the optional screws securing the Node
to the front of the rack (behind the locking tab).
5
Locate the lock levers on the sides of the inner rails (see Figure 36 ).
Unlock each lever by rotating it up to its release position.
