2.3 Unpacking The DA-3100 Mainframe is comprised of a frame, a backplane, up to two power supplies, and up to ten distribution boards. Prior to discarding packing material, compare the parts received against the packing list. Carefully inspect the layers of packing material for any components which may have been overlooked during the initial unpacking.

Chassis Installation 2.6 Cabling Considerable weight will be added to the rear panel of the DA-3100 Mainframe by the video cables and power cables. Therefore, all cables should be strained relieved and secured to racks or other supporting structures. Failure to provide adequate cable support can result in cables separating from connectors.
Page 19
Figure 6. Cabling Use the following rules when cabling the DA-3100 Mainframe: 1. Lay all cables in their intended positions, separating audio and video from power cables wherever possible. 2. Provide proper support for each cable during the cabling process. The use of tie-wraps is recommended, as in Figure 6.

Figure 7. Isolation Diode Installation In a redundant external power configuration, it should be noted that the DA-3100 Mainframe does not differentiate between the supply intended as primary power and the supply intended as backup. Therefore, consideration should be given to avoid overloading the power supplies by having less than one supply per frame in multi-frame configurations.

81-9059-0547-0 Rev. A DA-3100 2.9 Front Panel Installation To install the access door (front panel) of the DA-3100 Mainframe refer to Figure 8 and follow these steps: 1. Align the front panel to the front of the DA-3100 Mainframe. 2. Now slide the front panel onto the mainframe assembly until the slide locks snap into place.
