Dell Storage MD1420 Enclosures Hardware Owner's Manual

Models AMT, E03J, and E04J are intended for installation only in restricted access locations as defined in cl 1.2.7.3 of IEC 60950-1:2005.

On the basis of your configuration, your enclosure either supports up to 24 2.5-inch SAS hard disk drives in internal drive bays. Hard disk drives are connected to a backplane using hard disk drive carriers and are configured as hot-swappable.

CAUTION: : Do not turn off or reboot your enclosure while the hard disk drive is being formatted. Doing so can cause a hard disk drive to fail.

When you format a hard disk drive, allow enough time for the formatting to complete. High-capacity hard disk drives can take many hours to format.
