MOUNTING
Install the System 9770 in EIA-standard 19-inch (48.26 cm) racks.
CM9770-MXB
1. Install the CM9770-MXB mounting baffle first (refer to Figure 1).
The mounting baffle uses 1 rack unit (RU), and it has front and rear mounting ears, which are attached to the front and rear mounting racks.
The rear mounting brackets are adjustable to allow for different depths of cabinets.
The mounting baffle provides the following functions:
The mounting baffle helps to direct the heat from a lower matrix bay (or other equipment) toward the rear of the mounting baffle,
instead of allowing the heat to flow up into the matrix bay.
The mounting baffle supports the weight of the matrix bay.
The matrix bay is easier to install when it is sitting on top of the mounting baffle.

2. Install the CM9770-MXB matrix bay on top of the mounting baffle. Refer to Figure 2.
In a single-bay installation, always leave 1 RU of space above the matrix bay for airflow.
In a multiple-bay installation you do not need to leave additional RUs open between units. However, you must always leave 1 RU of space
above the upper bay.
NOTE:
Be sure to use all eight screws provided with the mounting baffle. The mounting baffle must be installed securely to support the
weight of the matrix bay.
NOTE:
Figure 2 illustrates the recommended mounting method. For an alternate, open-rack mounting method, refer to the
