The following illustration shows the controls, LEDs, and
connectors on the front of the NeXtScale nx360 M5 water-cooled technology
tray Type 5467.
Note: The illustrations in this document might differ slightly
from your hardware.
There are two separate nodes in a single tray. The following illustration
identifies the buttons, connectors, and LEDs on the control panel.

If you have the optional hard-disk drives(HDDs) or solid-state
drives(SSDs) installed, the following illustration identifies their
locations.

- Power button/LED
- When the water-cooled technology tray is connected to power through the Lenovo NeXtScale n1200 Enclosure
Type 5468,
press this button to turn on or turn off the water-cooled technology tray.
This button is also the power LED. This green
LED indicates the power status of the
water-cooled technology tray:
- Flashing rapidly: The LED flashes rapidly for the following
reasons:
- The water-cooled technology tray has been installed in a chassis. When you install the water-cooled technology tray, the LED flashes rapidly for up to 90 seconds while
the integrated management module (IMM2.1) in the water-cooled technology tray is initializing.
- The Lenovo NeXtScale n1200 Enclosure
Type 5468 does
not have enough power to turn on the water-cooled technology tray.
- The IMM2.1 in the water-cooled technology tray is not communicating with the Chassis Management Module.
- Flashing slowly: The water-cooled technology tray is connected to power through the Lenovo NeXtScale n1200 Enclosure
Type 5468 and
is ready to be turned on.
- Lit continuously: The water-cooled technology tray is connected to power through the Lenovo NeXtScale n1200 Enclosure
Type 5468 and
is turned on.
When the water-cooled technology tray is on, pressing this button causes an orderly shutdown
of the water-cooled technology tray so that it can be removed safely from the chassis.
This includes shutting down the operating system (if possible) and
removing power from the water-cooled technology tray.
If an operating system is running, you might
have to press the button for approximately 4 seconds to initiate the
shutdown.
Attention: Pressing the button for 4 seconds
forces the operating system to shut down immediately. Data loss is
possible.
- Locator LED
- Use this blue LED to visually locate
the server among other servers. This LED is used as a presence detection
as well. You can use Systems Director or IMM web interface to light
this LED remotely. This LED is controlled by the IMM.
- Check log LED
- When this yellow LED is lit, it
indicates that a system error has occurred. Check the Event logs for
additional information.
- System error LED
- When this yellow LED is lit,
it indicates that a system error has occurred. An LED on the system
board is also lit to help isolate the error. This LED is controlled
by the IMM.
- KVM connector
- Connect the console breakout cable
to this connector.
Note: It is best practice to connect the console
breakout cable to only one water-cooled technology tray at a time in each Lenovo NeXtScale n1200 Enclosure
Type 5468.
- Ethernet connectors
- Use either of these connectors
to connect the server to a network. When you enable shared Ethernet
for IMM2.1 in the Setup utility, you can access the IMM2.1 using either
the Ethernet 1 or the system-management Ethernet (default) connector.
See Using the Setup utility for more information.
- Ethernet link activity/status LED
- When any of
these LEDs is lit, they indicate that the server is transmitting to
or receiving signals from the Ethernet LAN that is connected to the
Ethernet port that corresponds to that LED.
- Management connector
- Use this connector to connect
the server to a network for full systems-management information control.
This connector is used only by the Integrated Management Module 2.1 (IMM2.1).
A dedicated management network provides additional security by physically
separating the management network traffic from the production network.
You can use the Setup utility to configure the server to use a dedicated
systems management network or a shared network.
