1.0 Engineering and Cabinet Selection

The 4220 and 4230 Series of "RH" and "XP" Cabinets are used for the rehabilitation or expansion of existingAT&T, Lucent or HUB cross connect cabinets. The new cabinets include brackets for the mounting of theexisting 76 terminal block frames and can be ordered to include new frames to add pair count to the cabinetusing the 3M™ 4320 Self-Strip System.

1.1 Engineeringa. To properly engineer a project using these cabinets, a "Pre-survey Trip" to the project site must be

made and four main questions have to be answered.

1) What specific size and type of old cabinet is on the project?

2) Are there any site "right-of-way" limitations?

(a) Does the new cabinet have to be single sided?

(1) -is there a fence or wall obstructions?

(2) -is there any community code height restrictions?

(b) Can the new cabinet be double sided?

3) Can the existing mounting pad be used?

(a) Is the pad level and not deteriorated?

(b) Where are the existing cable ducts?

(c) Are there spare ducts or room for new ducts for expansion?

(d) What are the dimensions of the pad?

(e) Can the pad be enlarged?

(f) If the existing mounting pad cannot be used, is a new "split" factory built pad or a new "pour in place" concrete pad right for this project?

4) If this is an expansion, how many pairs are desired to be added, now or in the future?

(a) Are the number of pairs limited by the site or cabinet configuration?

(b) Should pairs be added to just the rear of a new double sided cabinet?

1.4 Cabinet ClearancesUse the chart and drawing to help select the appropriate new cabinet. On your “Presurvey” trip, be aware ofany barriers or obstructions around the existing cabinet that would restrict the size of the new cabinet.

Cabinet Clearance Chart and Drawing

1.5 Mounting Pada. Existing Mounting Pad

1) It is recommended to use the existing pad or add concrete around it with new anchors and boltswhenever possible. Make sure that it is level and not deteriorating.

2) Many existing pads are constructed with the old cabinet and cable ports located near the rearedge of the pad. Using the dimensions from the clearance chart, verify that the pad willaccommodate the new cabinet. The existing pad must exceed the “A” and “B” dimensions asfollows:

- “A” dimension by 2 1/2"- “B” dimension by 11" on both side of the cable hole for the 4230 series- “B” dimension by 7" on both side of the cable hole for the 4220 series

3) It is recommended that the pad extend to cover the full door swing for both sides of the cabinet.

b. Split Composite Pads (factory built)

See your companies manufacturers for pad dimension. This method does require the removal of theold pad.
