Mounting the Removable Air Ramp
You must install a removable air ramp below the chassis when you install the chassis at the bottom of the
rack or when you install other equipment below the chassis. This additional air ramp is needed for proper
ventilation; see Figure 4-1 on page 4-5.
A pair of mounting brackets for a 19-inch rack and a 23-inch rack are available for each air ramp. The
bracket for the standard version of the air ramp requires two 10-32 x 0.25-inch flat-head screws; that for
the NEBS version of the air ramp requires three 10-32 x 0.25-inch flat-head screws.
The following sections describe the tasks to mount the removable air ramp at the bottom of the rack:
• Install the Air Ramp Mounting Brackets
• Install the Removable Air Ramp
Caution
Risk of equipment damage. Improper installation of a removable air ramp can cause loss of
cooling and damage a SmartEdge 1200 router. To reduce the risk and ensure proper cooling
of a SmartEdge 1200 router and any adjacent equipment, always mount the air ramp at the
same mounting depth as the SmartEdge 1200 chassis above it.
