Field Add-On with Universal Mounting Kit

H229-AB/AC

This chapter describes how to install the chassis rails of the Universal

Mounting Kit H229-AB/AC into a DECarray cabinet.

7.1 Chassis Rail Installation

To allow the length of the chassis rail to be adjusted to ﬁt the cabinet, one

end of the rail is extendible using a sliding rail bracket. Two round standoffs

are used to locate the chassis rail along the vertical cabinet rails. The round

standoffs are inserted into front and rear chassis rail locating holes to position

the chassis rail while it is fastened to the cabinet.

Note

Standoff location holes, front and rear, both sides, are holes 18, 36, 57,

and 75, as shown in Figure 7–1.

7.1.1 Chassis Rail Assembly

Before the chassis rail components can be mounted in the cabinet, they must be

assembled. Assemble the chassis rail components as follows (see Figure 7–2):

1. Position the rail bracket against the chassis rail, as shown in the

illustration.

2. Fasten the rail bracket to the chassis rail with the unbeveled nut bar and 4

screws, as shown. Leave the screws loose enough to allow the rail bracket

to be moved along the chassis rail.

3. Install a U-nut in the groove near the end of each of the beveled nut bars.

The ﬂat side of the U-nuts must be on the beveled side of the nut bar.
