Manager software to manage an ME484 JBOD. • The Dell EMC PowerVault ME484 JBOD Storage Enclosure Support Matrix and Dell EMC Storage PowerTools Server Hardware Manager Support Matrix provide information about the software and hardware compatibility requirements for the Server Hardware Manager software. -
Page 6: Mount The Enclosures In The Rack
The rails have been designed and tested for the maximum enclosure weight. Multiple enclosures may be installed without loss of space in the rack. Use of other mounting hardware may cause some loss of rack space. Contact Dell EMC to ensure that suitable mounting rails are available for the rack you plan to use. - Page 7 Once the enclosure is installed in the rack, dispose of the lifting straps. The straps cannot be used to remove the enclosure from the rack. Reinsert the rear panel modules and install the DDICs into the drawers. See the instructions in the Dell EMC PowerVault ME4 Series Storage System Owner’s Manual.
