g. When removing a FRU, immediately place it in anti-static packaging.
h. Avoid touching pins, leads, or circuitry.
Replace a 2U enclosure drive module in its carrier
The operator's (ops) panel registers either a logical fault or a hardware fault or both. The drive module in its carrier (DDIC)
uses an amber LED to identify various states and fault conditions. The asterisk (*) indicates a fault condition.

An important feature of the 2U enclosure design is redundancy. The 2U enclosure will maintain continuous operation during
the replacement of a single DDIC, if it is within the time limit of 5 minutes, since opening a drawer to remove a DDIC
significantly reduces airflow in the enclosure.
CAUTION If you remove any FRU while the expansion enclosure is powered up, you must replace it with a tested, good
spare within the allotted time for that FRU. If you do not replace the FRU and, when applicable, fully close the related drawer
within the identified time limit, you void the product warranty and the expansion enclosure might overheat, causing
equipment failure and possible data loss.
CAUTION Do not remove covers from any FRU. There is a danger of electric shock inside. Return the FRU to your
supplier for repair.
Drives in their carriers (DDICs) are hot-swappable, but you must replace the DDIC with one of the same type and with an equal
or greater capacity. The steel carrier provides thermal conduction, radio frequency, electromagnetic induction, and physical
protection. For this task, treat the drive carrier and its installed drive as a single FRU.
