• Passively cooled:
– Working from the bottom of the bay, leave a 1U space between the bottom of the rack
and the first shelf, install a MX2820 shelf (P/N 1186001L2).
– Leave a 1U space, install a 1U passive heat baffle (P/N 1180002L1).
– Leave an additional 2U space, (4U total between shelves), and install another MX2820
shelf.
– Repeat these steps to fill the bay leaving a 2U space above the top-most shelf.
