Board Set Carrier Plates

The board set carrier plates inside the Sun Fire E25K/E20K systems require special
handling. There are also three different configuration setups depending on the board
sets the carrier plate is assigned to carry. For increased thermal control, a carrier
plate with an air dam has been designed for slots 4, 5, 13, and 14. This chapter
contains the replacement procedures for these three configurations.
