Upon NVMe SSD insertion, an LED initiation sequence will be visible - lighting each LED in the carrier in sequence from left to
right. The sequence will cycle until the drive is recognized by the system. When the SSD is recognized by the system - the Do Not
Remove LED will be solid white and the Power LED will be solid green.

Hot-plug fans

The server supports redundant hot-plug fans to provide proper airflow to the system when a primary fan
fails.
CAUTION: To avoid damage to server components, a fan or fan blank must always be
installed in fan bay 1.
CAUTION: To avoid damage to the equipment, do not operate the server for extended
periods of time if the server does not have the optimal number of fans installed. Although the
server might boot, Hewlett Packard Enterprise does not recommend operating the server
without the required fans installed and operating.
