If you are installing your switch in an enclosed or partially enclosed rack, we strongly recommend that you
verify that your site meets the following guidelines:
• Verify that there is a minimum of 6 inches (15 cm) of clearance between the sides, front, and back of
any enclosure, and both the chassis air intake grill and the chassis air exhaust grill along with the power
supply unit intakes and exhausts. The upright columns of a relay rack may be located less than the
recommended side spacing provided there are substantial cutouts, holes, or vents in the structure to allow
adequate air flow through the chassis.
• Verify that the ambient air temperature within the enclosed or partially enclosed rack is within the chassis
operating temperature limits. After installing the chassis in the rack, power up the chassis and allow the
chassis temperature to stabilize (approximately 2 hours).
Measure the ambient air temperature at the chassis air intake grill by positioning an external temperature
probe 1 inch (2.5 cm) away from the chassis left side, and centered on the chassis both horizontally and
vertically.
