Hazardous energy is present when the water-cooled technology tray is connected to the power source. Always replace the compute tray cover before installing the water-cooled technology tray.
If you are installing a water-cooled technology tray model without an integrated Ethernet controller, you must install a network interface adapter before you install the water-cooled technology tray in the chassis for management network communication. For a list of supported optional devices for the water-cooled technology tray, see the IBM ServerProven website.
To install the water-cooled technology tray in a chassis, complete the following steps.
Figure 1. Installing the water-cooled technology tray in a Lenovo NeXtScale n1200 Enclosure Type 5468
Select the tray bay.
Notes
If you are reinstalling a water-cooled technology tray that you removed, you must install it in the same tray bay from which you removed it. Some water-cooled technology tray configuration information and update options are established according to tray bay number. Reinstalling a water-cooled technology tray into a different tray bay can have unintended consequences. If you reinstall the water-cooled technology tray into a different tray bay, you might have to reconfigure the water-cooled technology tray.
To maintain proper system cooling, do not operate the Lenovo NeXtScale n1200 Enclosure Type 5468 without a water-cooled technology tray or tray bay filler in each tray bay.
Make sure that the front handles on the water-cooled technology tray are in the open position.
Slide the water-cooled technology tray into the tray bay until it stops.
Push the front handles on the front of the water-cooled technology tray to the closed position.
Note
After the water-cooled technology tray is installed, the IMM2.1 in the water-cooled technology tray initializes. This process takes approximately 90 seconds. The power LED flashes rapidly, and the power button on the water-cooled technology tray does not respond until this process is complete.
Press the power button to turn on both systems in the water-cooled technology tray (see Turning on the server for instructions).
Make sure that the power LED on the water-cooled technology tray control panel is lit continuously, indicating that the water-cooled technology tray is receiving power and is turned on.
If you have other water-cooled technology tray to install, do so now.
If this is the initial installation of the water-cooled technology tray in the chassis, you must configure the water-cooled technology tray through the Setup utility and install the water-cooled technology tray operating system.
If you have changed the configuration of the water-cooled technology tray or if you are installing a different water-cooled technology tray from the one that you removed, you must configure the water-cooled technology tray through the Setup utility, and you might have to install the water-cooled technology tray operating system (see Using the Setup utility).
