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 “Installation checklist” (page 36) , and follow safe-handling
instructions provided in “Unpacking and preparing the enclosure” (page 38) .
• 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 page 42 .

After installing the enclosure, and before installing the Discs, see “ESD precautions” (page 78) .

To install DISC drive modules into a rack-mounted enclosure, face the front panel, and pull the enclosure outward
on its rails. Open the top cover(s) to access the DISC module slots. See
Figure 8 (page 20) for top lids, and see
and Figure 13 (page 24) for DISC slots and FRU module slot indexing. See also “Installing an LFF drive carrier
module” (page 88) .
• The belt straps and optional lift handles are designed to support the weight of the enclosure as shipped. Neither
safely supports a fully populated enclosure. See also
“Unpacking and preparing the enclosure” (page 38) .
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
“Installing the rackmount railkit” (page 42) for additional 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 when operating 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 79) .
• Observe the hazardous voltage warning label affixed to power supply modules.
