6600 series air plenums

The HP ProCurve 6600 Series Air plenum is designed to help preserve cold-aisle/hot-aisle separation for
improved cooling efficiency when the 6600 switch is co-located with top-of-rack servers . In typical top-of-rack
server connectivity environments, the Ethernet ports face the hot aisle to align with server I/O . When a switch
is mounted in a server rack, it is typically positioned toward the back of the rack to facilitate cabling, which
usually leaves a sizeable air gap in the rack where cold air can flow around the switch . The 6600 series air
plenum provides an enclosed pathway where cold air cannot escape around the switch and thus facilitates hot-
aisle and cold-aisle separation . This plenum is especially useful in environments where customers are concerned
about maintaining temperature and pressure gradients due to limited cooling capacity, or want to save on
cooling costs .
Figure 15 details what the 6600 air plenum would look like mounted with a 6600 switch with the 4-post rail kit .

The 6600 series air plenum helps promote stronger hot-aisle/cold-aisle separation by maintaining temperature
and pressure gradients in configurations where the 6600 switch is co-located with servers at the top of rack .
The air plenum prevents cold air from leaking around sides of the 6600 switch to promote more efficient
cooling and is recommended with installations where the 6600 switch is mounted with Ethernet ports facing the
hot aisle . The 6600 series air plenum (J9480A) is designed for use with the 6600-48G, 6600-48G-4XG, and
6600-24XG switches . Figure 16 details the air plenum kit .

The 6600-24G/24G-4XG air plenum is used with 6600-24G and 6600-24G-4XG switches that require a
longer plenum due to shorter product depth . The plenum helps promote stronger hot-aisle/cold-aisle separation
by maintaining temperature and pressure gradients in configurations where the 6600 switch is co-located with
