The Challenge deskside chassis uses both half-height and full-height
front-loading devices. The power must be off to install or remove storage
devices.
FLDs are easily removed and replaced, allowing flexible and secure data
management.
Be careful not to push the drive ID selector when moving the sled
Note:
release lever to the right. An incorrect SCSI device ID may cause SCSI bus
failure. FLDs can be installed and removed with the front door closed and
only the drive door open.
Caution: Use proper handling and storage procedures to minimize the loss
of data and equipment. In particular, do not remove disk drives while they
are operating. Always power off the system before removing an FLD. Be
sure to use standard electrostatic discharge prevention precautions when
removing, storing, transporting, or replacing an FLD.
