• There are no user-replaceable parts inside the PCM. Do not attempt to repair a

PCM. Disassemble of a PCM voids the warranty.

Recycling of Waste Electrical and Electronic Equipment (WEEE) 

At the end of the product’s life, all scrap/ waste electrical and electronic equipment
should be recycled in accordance with local/national regulations applicable to the
handling of hazardous/toxic electrical and electronic waste materials.

NOTE :

Observe all applicable safety precautions, such as weight restrictions, 
handling batteries, and lasers, detailed in the preceding paragraphs 
when dismantling and disposing of this equipment. 

ESD Precautions

CAUTION !

Observe all conventional ESD precautions when handling the 
SS8460 plug-in modules and components. Avoid contact with 
backplane components and module connectors. 

Data Security

• Each enclosure contains up to 84 removable disk drive modules. Disk units are

fragile. Handle them with care, and keep them away from strong magnetic fields.

• Always allow new disks to acclimate to room temperature (for 1 to 2 hours) prior

to installation.

•

ALL

the supplied plug-in modules and required blank modules must be in place for

the air to flow correctly around the enclosure and also to complete the internal
circuitry.

• If the enclosure is used with modules or blanking plates missing for more than a few

minutes, the enclosure can overheat, causing power failure and data loss. Such use
may also invalidate the warranty.

• If you remove a disk module, replace it immediately. If it is faulty, replace it with a

disk module of the same type and capacity.

• Ensure that all disk drives are removed from the enclosure before attempting to

move the rack installation.

• Do not abandon your backup routines. No system is completely foolproof.

Due to the danger of electrical shock, do not remove covers from the 
PCM. Return the module to your supplier for repair.
