1 Product Description
1.1 General Description
The Flex Frame (ODF-FF19CM) shown in Figure 1 , is an optical distribution frame providing a
connection point between facility cables in a data center. Facility cables are high-fiber-count cables containing rollable ribbons, and of a type suitable for being routed indoors or outdoors.
The basic product consists of a 19-inch seismic rack with two cable managers, one on each side.
Two sizes are offered: ODF-FF19CM-40RU, which has 40 rack units of connector panel spacing, and ODF-FF19CM-36RU, which has 36 rack units.
The ODF-FF19CM is also offered with an integral Splice Cabinet (ODF-FF19CM-36RU-SP). The
Splice Cabinet is installed on the back of the left cable manager (when viewed from the front).

3.7 Installing Aftermarket Rack Numbering Labels
The same 43 RU 19” seismic equipment rack is used in both the 36 RU Flex Frame (ODF-
FF19CM-36RU) and the 40 RU Flex Frame (ODF-FF19CM-40RU). In both applications, several rack units are sacrificed at the bottom of the rack for the lower trough system and the rack passthrough radius limiters. As such, the silk-screened rack unit numbering provided on each side of the two vertical rails on the rack must be updated with adhesive rack unit numbering tape to reflect the correct RU numbering for the particular frame. Use the following procedure referring to
Figure 14 .
Figure 14. Silk-Screened Rack Unit Numbering
For the 36 RU Flex Frame (ODF-FF19CM-36RU) – locate the four rolls of adhesive RU labeling tape and carefully cut off and discard the RUs numbered from 37-52 from each tape. Beginning at the uppermost rack unit on the rack, begin applying the label tape over the silk-screened numbering so that only the adhesive label numbers are visible and work your way downward from top to bottom. At the top of the rack, the silk-screened RU number 43 should correlate to the adhesive RU number 36 and at the bottom of the rack, silk-screened RU number 8 should correlate to the adhesive RU number 1. Repeat this procedure for the remaining rack rails.
For the 40 RU Flex Frame (ODF-FF19CM-40RU) – locate the four rolls of adhesive RU labeling tape and carefully cut off and discard the RUs numbered from 41-52 from each tape. Beginning at the uppermost rack unit on the rack, begin applying the label tape over the silk-screened
Page 14 of 22. © 2020 CommScope, Inc.
TC-96292-IP numbering so that only the adhesive label numbers are visible and work your way downward from top to bottom.
At the top of the rack, the silk-screened RU number 43 should correlate to the adhesive RU number 40 and at the bottom of the rack, silk-screened RU number 4 should correlate to the adhesive RU number 1. Repeat this procedure for the remaining rack rails
3.8 Installing Cable Managers and Accessories
Once the seismic rack is anchored in the floor, the cable manager and accessories can be installed. Use the following procedure.
Note: The fasteners should NOT be fully tightened until the lower troughs have been installed so that they can be properly aligned.
1.
Fasten the left and right cable managers to the frame, aligning the components as
shown in Figure 15 .
