• When logged in to the BMC and using the power control page to power off the sever.
• Using the remote console screen GUI power-off button, if a KVM RMM4Lite session is
established through the BMC.
For an MIS NAS JBOD Unit, the power button on the front panel will turn off the power to that
I/O module. If an additional JBOD module is installed and powered on, it, the fans and the drives
will remain on until it, too, is powered off.
Ensure that rack internal cabling is not blocking the front or rear airflow through the MIS NAS or
JBOD units. Reduced airflow may cause an over-temperature (overtemp) condition in the MIS
NAS or JBOD enclosures.
Important: Failing to keep the enclosure cover(s) in place during operation may cause airflow
interruption to critical internal components and consequent overheating and shutdown.
Leave enough clearance in front of the rack to enable you to open the front door completely (~25
inches) and approximately 30 inches of clearance in the back of the rack to allow for sufficient
airflow and ease in servicing.
