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” on page
62 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.
Rear view
The following illustration shows the connector on the rear of Lenovo NeXtScale n1200 Enclosure Types 5468
and 5469.
