5U84 enclosure core product
5U84 enclosure—front panel components on page 16 and 5U84 enclosure system - plan view of drawer accessed from front
panel on page 16 show component locations—together with CRU slot indexing—relative to the 5U84 enclosure front panel
with drawers, and the rear panel.
The 5U84 supports up to 84 DDIC modules populated within two drawers (42 DDICs per drawer; 14 DDICs per row).
NOTE:
● The 5U84 does not ship with DDICs installed. DDICs ship in a separate container, and must be installed into the
enclosure drawers during product installation and setup.
● To ensure sufficient circulation and cooling throughout the enclosure, all PSU slots, cooling module slots, and IOM slots
must contain a functioning CRU. Do not replace a faulty CRU until the replacement is available and in hand.
