(Trained service technician only) Use these instructions
to install the chassis midplane in the NeXtScale nx360 M5 water-cooled
technology tray.
To install the chassis midplane, complete the following
steps.
- Carefully align the chassis midplane with the guide pins
in the chassis.
Figure 1. Installation
of a chassis midplane into a chassis
- Slide the chassis midplane half way into the chassis. Put
a screwdriver or a stick in the middle of the chassis midplane so
your hands are free.

Attention: - You must hold the chassis midplane up against the top inside of
the chassis shell and keep the chassis midplane vertical during installation.
If the chassis midplane is not inserted correctly, the guide pins
can contact the chassis midplane connectors and damage the connector
pins.
- Do not grasp the connectors on the chassis midplane when you install
it in the chassis. Touching the connectors might damage the connector
pins.
- Make sure that the fan and power controller cable is out of the
way when you slide the chassis midplane into the chassis.
- Connect the two cables back to fan power connectors and
fan signal connectors back to the chassis midplane.
- Slide the chassis midplane all the way into the chassis
until it stops.
- Tighten the three captive screws that secure the chassis
midplane to the chassis.
- Rotate the top cover inwards.
- Tighten the three captive screws on the top cover.

Reassemble the chassis and program the vital product data
(VPD) that is stored on the card. Complete the following steps:
Slide the enclosure into the rack.

- Connect any cables that you disconnected from the modules in the
rear of the chassis.
- Connect the chassis to power (see n1200 Enclosure Installation
and Service Guide).
- Write down new chassis midplane serial number (for example: Y030UN34B063) and UUID (for example: 2E2B686CC6B311E2907C6EAE8B16A49E).
- Update the server firmware to the latest level (see n1200 Enclosure
Installation and Service Guide).
- Log in to the web interface (see n1200 Enclosure Installation
and Service Guide).
- Go to System Information section, click on the Midplane
VPD tab.
- Update the new chassis midplane serial number and UUID onto the
fan and power controller (see n1200 Enclosure Installation and Service
Guide).
- Close the release handles on the compute nodes in order to seat the nodes in the chassis midplane connectors.
- Restart any compute nodes that you shut down. See the documentation that comes with the compute
node for detailed instructions.
- The fan and power controller is powered-on automatically by the
IMM2.
