Placement
	Consider the following issues when installing your PathBuilder S24x, 26x, and 27x
Considerations	switch in an equipment rack:

Space

A PathBuilder S24x, 26x, and 27x switch and EIA rackmount assembly occupies 7.0 inches, or 4 U NEMA rack space increments.

Power

Allow enough room behind the EIA equipment rack to connect the power cord and devices. Refer to this manual for maximum power load, when connecting to a 15 amp internal convenience power outlet strip.

Thermal

For proper ventilation, do not cover air vents at the rear of the unit. Where a front door is present on a rackmount cabinet, installation of the PathBuilder S24x, 26x, and 27x switch must allow a 2-inch clearance between the door and the PathBuilder S24x, 26x, and 27x switch air inlet to provide sufficient air flow.

Stability

When installing the PathBuilder S24x, 26x, and 27x switch in a non-3Com cabinet or with other vendors’ equipment, the PathBuilder S24x, 26x, and 27x switch should be positioned so that the resulting system rack remains stable during installation on a 10-degree ramp or when 56 pounds of force is applied to the top of the cabinet.
