MOUNTING

Install the System 9780 in EIA-standard, 19-inch (48.26 cm) racks.

CM9780-MXB

1. Install the CM9780-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 rails.

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.

Figure 1.

2. Install the CM9780-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
