Environmental Requirements; Power Supply Unit Specifications - Seagate Exos E 4U106 Hardware Installation And Maintenance Manual

NOTE:
Weight totals subject to variance in individual component weights.
Weight total changes depending on the number of DDIC modules installed. Weight totals with DDICs shown are
for the maximum number of DDICs supported by Exos E 4U106.
Weight totals do not include power, SAS, or serial cables as those cables can have a range of lengths.
