After installing the 2.5-inch hot-swap drive, check the drive status LED to verify if the drive is operating
correctly:
• If the yellow LED is lit continuously, it is malfunctioning and must be replaced.
• If the green LED is flashing, the drive is functioning.
Note: If the server is configured for RAID operation through a ThinkSystem RAID adapter, you might have to
reconfigure your disk arrays after you install drives. See the ThinkSystem RAID adapter documentation for
additional information about RAID operation and complete instructions for using ThinkSystem RAID
adapters.
