Page 3: Product Introduction
The first three components of the InRackCDU system are delivered pre-filled with server cooling liquid. There is no need for data center staff to handle server cooling liquid when installing the InRackCDU or when removing and replacing servers during maintenance. Tubes connect between the CDM and server coolers with locking dripless quick connectors. -

Coolant The server coolant in InRackCDU systems is a mixture of DI water, propylene glycol with some additional additives for corrosion resistance. It is a safe, environmentally friendly liquid. It provides freeze protection and inhibits corrosion and biological growth within the system. -
Page 7: Important Information
Material damage may be caused to the monitoring system if this requirement is not met. Only transport the InRackCDU and CDMs in the original packaging or in packaging that protects it from impacts and jolts. ... - Page 8 The InRackCDU system ships out from the factory in a rack. When the customer orders the InRackCDU system and LC Server at the same time, the water- cooled tubes that connect the InRackCDU system and LC Server are connected by the factory.

Once this initial process has been completed, all the servers may be powered off and on simultaneously. This row-by-row power on sequence only needs to be followed the first time all servers are connected to the InRackCDU System. Asetek InRackCDU Installation, Operation & Maintenance Guide 17... -
Page 19: Routine Maintenance
7 Routine Maintenance There is a reservoir in the 4u InRackCDU cabinet. As the liquid cooling system runs, liquid gradually permeates through the rubber tubing and plastic parts in the system. The reservoir contains sufficient fluid to replenish the liquid that permeates out of the system for more than 50,000 hours of 24/7/365 operation. -
Page 20: Replacing Power Supplies
Before screwing the plug back into the reservoir, replace the black O-ring on the plug. Replacement O- rings (Asetek PN P00004415) are included on the zipper bag on the below picture and can be purchased from Asetek. Please keep O-rings by customer for preparing that servicemen will use and replace O-ring. -
