Chapter 3: FRU Removal and Replacement Procedures
Opening and Closing the Node
Quantum DXi6900-S Field Service Manual

Opening and Closing the Node
WARNING: Opening or removing the system cover when the system is on may expose you to a risk of electric
shock.
Caution:
Use appropriate ESD precautions, including the use of a grounding strap, when working
inside the Node.
Some DXi6900-S FRU replacement procedures require removing the Node from the rack and opening the
top cover to access the inside of the Node. Refer to the following sections:
l
Opening the DXi6900-S Node below

Closing the DXi6900-S Node on page 68
Opening the DXi6900-S Node
Additional Information
l
You do not need to remove the Node from the rack to remove and replace internal components. Using
the DXi6900-S 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.
l
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 DXi6900-S Node from the rack and remove the top cover:
1. Shut down the DXi6900-S Node (see
Turning Off the DXi6900-S 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
). Unlock each lever
by rotating it up to its release position.
