Lenovo NeXtScale nx360 M5 Installation And Service Manual page 155

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 http://www.lenovo.com/ serverproven/.
To install the water-cooled technology tray in a chassis, complete the following steps.

Figure 49. Installing the water-cooled technology tray in a Lenovo NeXtScale n1200 Enclosure Type 5468
Step 1. Select the tray bay.
1. 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.
2. 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.
Step 2. Make sure that the front handles on the water-cooled technology tray are in the open position.
Step 3. Slide the water-cooled technology tray into the tray bay until it stops.
Step 4. 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.
Step 5. Press the power button to turn on both systems in the water-cooled technology tray (see "Turning
on the server" on page 19 for instructions).
Step 6. 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.
Step 7. 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.
