f. Use conductive field service tools.
g. When removing a FRU, immediately place it in anti-static packaging.
h. Avoid touching pins, leads, or circuitry.
Replace a 5U enclosure drive module in its carrier
The operator's (ops) panel registers either a logical fault or a drawer hardware fault or both. You must locate a faulty drive in
its carrier (DDIC) within the related drawer by its amber fault condition LED.
An important feature of the 5U enclosure design is redundancy. The 5U enclosure will maintain continuous operation during
the replacement of a single DDIC, if it is within the time limit of 7 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.
The steel carrier provides thermal conduction, radio frequency, electro-magnetic induction, and physical protection. For this
task, treat the drive carrier and its installed drive as a single FRU.
To replace a 5U enclosure drive module in its carrier:
1. Complete the following actions to open the related drawer:
a. Facing the front of the 5U enclosure, determine which drawer has a fault condition by the fault LEDs on the ops panel
and drawer panels.
