Safety guidelines

Safe handling

CAUTION: Use this equipment in a manner specified by the manufacturer: failure to do this may cancel the
protection provided by the equipment.
• For new enclosures, prepare the site for installation per
safe-handling instructions provided in
• Unplug the enclosure before you move it, or if you think that it has become damaged in any way.
• A safe lifting height without a mechanical lift is 20U (~35").
• The 4U106 ships with all FRUs other than the discs installed; however, the DISCs must be installed as part of
the system setup, after the enclosure is securely mounted in the rack.
Before installing the enclosure into a rack, see the WARNING on

After installing the enclosure, and before installing the DISCs, see

To install DISC drive modules into a rack-mounted enclosure, face the front panel, and pull the enclosure

module slot indexing. See also
• The belt straps and optional lift handles are designed to support the weight of the enclosure as shipped. Neither

CAUTION: Use a suitable mechanical lift for hoisting the enclosure for installation into the rack:
• Fully configured Exos E 4U106 enclosures can weigh up to ~131 kg (289 lb). Do not install DISCs until after
the enclosure is secured into the rack.
• When positioning the enclosure into its rack space, use the belt straps (quantity three) or the optional enclosure
lift handles (two handles per side). See also
information.
• Observe the lifting hazard label affixed to the storage enclosure.
•
Do not use vacuum lift because it can potentially damage the 4U106 enclosure.

Operation

IMPORTANT: It is essential that all FRU slots hold modules or module blanks to use the enclosure for more than
the allowed service times for a FRU module.
•
Observe the caution label affixed to the module being replaced.
• Replace a defective FRU with a fully operational FRU as soon as possible. Do not remove a defective FRU
module unless you have a replacement model of the correct type ready for insertion.
•
Before removal/replacement of a PSU, disconnect supply power from the PSU to be replaced. Refer to
"Replacing a PSU module" (page
