AC power cord, compatible
3. Prevent electrostatic discharge from damaging the storage enclosure or its components.
a. Keep a static-protected work surface clear of clutter, including plastic, vinyl, and foam.
b. Transport and store FRUs in static-safe containers.
c. Keep FRUs in their containers until reaching a clear, static-protected work surface.
d. Always wear a grounded ESD wrist strap that meets a minimum 1 megohm (± 10 percent) resistance standard
and that is snug against your skin.
e. Use heel straps, toe straps, or boot straps on both feet to ground to your conductive floor or dissipating floor mat
or use a portable field service kit with a grounded, static-dissipating work mat.
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 disk drive

Each of the 96 drives in the main bay and each of the ten drives in the auxiliary bay stores and provides access to
system data. Each drive slot can hold a single low-profile 3.5-in or 2.5-in form factor drive in a carrier or a carrier with
adapter, respectively.
An important feature of the storage enclosure design is redundancy. You can still maintain continuous operation during
the replacement of a single disk drive for up to eight (8) minutes.
CAUTION If you remove any FRU while the storage enclosure is powered up, you must replace it with a known
good spare within the allotted time for that FRU. If you do not replace the FRU and, when applicable, close the related
cover within the identified time limit, you void the product warranty and the storage enclosure might overheat, causing
equipment failure and possible data loss.
CAUTION When you suspect a disk drive or connection is the fault, halt all input and output operations to the
drive group or groups from all hosts as a data protection precaution. Make sure your regularly scheduled backup is good
and that you conduct another backup at the time of failure as an additional data protection precaution.
To remove and replace a disk drive:
1. If you plan on removing all disk drives, properly shut down the storage enclosure.
2. Retrieve the new disk drive in its static-protected container, ready to access and use it upon removal of the faulty
one.
3. (Optional) As an extra safety measure while installing disk drives, support the storage enclosure with a mechanical
lift to avoid any potential issues caused by downward forces.
