Installation
IMPORTANT: Do not power on server nodes at this point. Section 6 – System Startup, will outline when
servers should be powered on.
5.1
Mounting the CDU Cabinet
Mount the rails 4U spaces down from the top of the rack (i.e. U39 in a 42U rack or U45 in a 48U rack).
Ensure that rails are rated to support at least 80kg of weight. The CDU Cabinet weighs approximately 80kg
(~180lbs) and a server lift should be used to lift and place inside of the rack.
The screws that are pressed into the CDU Cabinet are M5. Install an M5 cage nut into the rack.
5.2
Installing the Facility Hoses to the CDU Cabinet
Facility tube connections are available on the rear right side of the CDU Cabinet. The facility liquid supply
and return lines are marked with an “S” and “R”, respectively. The supply hose will have a female Camlock
and the return hose will have a male Camlock.
Remove the protection caps from the return and supply connections. Insert the provided EPDM gasket
between the flanges and install the tri-clamp locking ring.
For bottom feed connections, the minimum size opening that needs to be cut in the floor tile is 150mm x
150mm.
Important: For rack widths
700mm, install the pipe adapter in between the facility pipe connection
on the CDU and facility hose.
