PROBLEM DESCRIPTION:
RSM Array shelves (p/n 370-2343) may collapse if the weight placed upon
them is greater than 40 lbs.(18.2 kg). Disk arrays such as the D1000
may cause a collapse, potentially dropping the array to the floor in
the worst case and causing physical stress to the system, connectors
and data stored in the disk array. Having a shelf collapse under the
weight of a disk array or other system may result in hard drive damage,
cable disconnect, unsecured drives dropping to the floor, loss of data,
customer quality complaints, and potential injury to customers and SMI
employees.
Following are the the number of systems that may be affected by this
problem:
-----------------------
| E10000 | Qty: 650 |
| A3500 | Qty: 4000 |
| A3000 | Qty: 6000 |
| RSMArray | Qty: 6000 |
-----------------------
Conditions which can cause the failure: placing more than 40 lbs on the
RSM shelves; for example stacking more than one RSM Array on a shelf,
putting a D1000 on the shelf, putting other systems weighing more than
40 lbs on the shelf.
The shelf was a product originally designed to hold the RSM Array,
which weighs approximately 40 lbs. Newer products containing more hard
drives are used to replace these older RSM Arrays and sometimes the
correct rack mount kits are not utilized. Instead, the newer shelves
weighing more than the weight limit of the RSM Array Shelf are
installed, and this may stress the supports beyond their designated
capacities. This overloads the shelf, ripping the solid rubber
supports and dropping the disk array or other equipment to the floor.
Visual inspection: The shelves will be attached to the front and back
of the chassis or rack by rubber bumpers, and will have a sheet of
metal to support the equipment. Inspect the bumpers and general
condition of the shelf. If the bumpers are deformed due to weight, age,
or manufacture (cracking, crazing, chunks missing from the bumper), the
shelf may require replacement.
IMPLEMENTATION:
---
| | MANDATORY (Fully Pro-Active)
---
---
| | CONTROLLED PRO-ACTIVE (per Sun Geo Plan)

| X | REACTIVE (As Required)

CORRECTIVE ACTION:
Enterprise Customers and authorized Field Service Representatives may
avoid the above mentioned problem by following the recommendations and
guidelines as shown below while servicing the RSM Array Racks.
1) If the RSM shelf is supporting a system within its weight limit
(< 40 lbs), visually inspect the RSM Array. Inspect shelves
in the 56", 68", and 72" racks to see if there are any signs of
aging
on the rubber supports (cracks, crumbling, etc).
If cracking or crazing of the rubber bumper is seen, obtain the
correct spare from your local Remote Stocking Location. To replace
the RSM Array shelf with the same shelf, (ONLY for use with existing
RSM Arrays - do not use for any other disk array) use FRU part
number: F370-2343.
2) If the shelf is supporting a system that exceeds its weight limit
(>40 lbs), immediately order the correct rack mount kit for that
system/chassis combination, and be aware that the system may need to
be deinstalled to prevent a catastrophic collapse. Use your best
judgement to determine if a shelf is likely to fail. Excessive
deformation of the rubber bumpers may indicate impending failure.
