Chapter 3 Installing the WAVE-574
Rack Mounting and Cabling the WAVE-574
When vertical space in the rack is not filled by a WAVE appliance or rack
component, the gaps between the components cause changes in airflow through
the rack and across the WAVE appliances. Cover all gaps with filler panels to
maintain proper airflow.
Caution
Always use filler panels to fill empty vertical spaces in the rack. This arrangement
ensures proper airflow. Using a rack without filler panels results in improper
cooling that can lead to thermal damage.
•
Observe the following additional requirements to ensure adequate airflow and
to prevent damage to the equipment:
– Front and rear doors—If the 42U rack includes closing front and rear
doors, you must allow 5,350 sq cm (830 sq in) of holes evenly distributed
from top to bottom to permit adequate airflow (equivalent to the required
64 percent open area for ventilation).
–
Side—The clearance between the installed rack component and the side
panels of the rack must be a minimum of 7 cm (2.75 in).
Rack Mounting and Cabling the WAVE-574
To install the WAVE appliance into a rack with square, round, or threaded holes,
refer to the instructions that ship with the rack hardware kit.
Use the following information (see Figure 3-1 ) when connecting peripheral cables
and power cords to the WAVE appliance.
Warning
To reduce the risk of electric shock, fire, or damage to the equipment, do not
plug telephone or telecommunications connectors into RJ-45 connectors.
