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.
