Rules for handling disk carriers for DS4486 disk shelves
DS4486 disk shelves are shipped with the majority of the disk carriers—each containing two
drives—removed to reduce the chassis weight for installation. Because you must unpack and
install the disk carriers into the disk shelf, you must understand and follow the disk carrier
handling rules to avoid damaging the disk drives.
To avoid damaging the disk drives in the disk carrier, always follow these rules:
Attention: The two disk drives housed in each disk
carrier are fragile! Improper handling of disk drives is
the leading cause of disk drive damage.
• Prevent electrostatic discharge (ESD):
◦ Keep the disk carrier in the ESD bag until you are ready to install it.
◦ Do not insert a metal tool or knife into the ESD bag.
Open the ESD bag by hand or cut the top off with a pair of scissors.
◦ Retain the ESD bag and any packing material for the disk carrier in case you must return it
later.
Note: NetApp requires that all returned disk carriers be in an ESD-rated bag.
◦ Always wear an ESD wrist strap grounded to an unpainted surface on your storage
enclosure chassis.
If a wrist strap is unavailable, touch an unpainted surface on your storage enclosure chassis
before handling the disk carrier.
• Handle disk carriers gently:
◦ Never touch the connector pins on a disk carrier.
◦ Do not force the disk carrier into the enclosure.
The disk carrier slides easily into the enclosure, and gentle, firm pressure completely
engages the carrier latch.
◦ Do not stack disk carriers on top of each other.
◦ Do not bang disk carriers against surfaces.
