HP Blade Server bh7800 Overview
Slot Blocker Assembly

Slot Blocker Assembly
The bh7800 uses a closed, pressurized cooling system. Fans draw air in the bottom at the front of the chassis,
direct it upwards across the front blades, over the top of the backplane, downwards over the rear blades and
into the power supplies where it exits out the back of the bh7800.
Any slot that isn’t occupied by a blade must contain a slot blocker to channel cool air in the proper direction to
maintain the cooling system pressure. A caution label on the chassis (bottom figure) indicates how serious
this requirement is.
