ADMONISHMENTS

Important safety admonishments are used throughout this manual to warn of possible hazards to persons or equipment. An admonishment identifies a possible hazard and then explains what may happen if the hazard is not avoided. The admonishments — in the form of Dangers, Warnings, and Cautions — must be followed at all times. These warnings are flagged by use of the triangular alert icon (seen below), and are listed in descending order of severity of injury or damage and likelihood of occurrence.

Danger: Danger is used to indicate the presence of a hazard that will cause severe personal injury, death, or substantial property damage if the hazard is not avoided.

Warning: Warning is used to indicate the presence of a hazard that can cause severe personal injury, death, or substantial property damage if the hazard is not avoided.

Caution: Caution is used to indicate the presence of a hazard that will or can cause minor personal injury or property damage if the hazard is not avoided.

GENERAL SAFETY PRECAUTIONS

Danger: Infrared radiation is invisible and can seriously damage the retina of the eye. Do not look into the ends of any optical fiber. Do not look directly into the optical adapters of the adapter packs. Exposure to invisible laser radiation may result. An optical power meter should be used to verify active fibers. A protective cap or hood MUST be immediately placed over any radiating adapter or optical fiber connector to avoid the potential of dangerous amounts of radiation exposure. This practice also prevents dirt particles from entering the adapter or connector.

5 INSTALLING A RAISED FLOOR CABLE BRACKET

If cables will be brought into the frame from under the raised floor, a Raised Floor Standard Cable Clamp Bracket (available from CommScope) must be installed on the rear side of the frame in the bottom right corner.

The kit is designed for standard size cables, with an Outside Dia meter (OD) of up to 0.8 in. (2.03 mm). If large cables are to be installed, with an OD in the range from 0.8 to 1.03 in. (2.03 to 26.16 mm), a large cable kit (NG4-ACCRFCLMP3) is also required.

This procedure covers both standard and large cables, and assumes that the installer has the kit or kits required.

TECP-90-708 • Issue 5 • April 2017

Use the following procedure to install a raised floor cable clamp bracket.

1. Determine whether the cables to be installed are standard or large as defined above. Set

out the bracket plate (largest piece in the kit) and identify the hole pattern to be used for mounting cables, referring to Figure 33 on Page 36. There are separate hole patterns for large and standard cables.

Note: The Row locations shown in this same figure (Figure 33 on Page 36) will also be used to figure out the DIM ‘A” values when breaking out the cables in the next step.

7. Prepare each cable as follows, referring to Figure 40:

a. Pull the cable up through the hole. b. If the cable being installed is an NG4access cable terminated with one or more cabled

module(s), obtain the appropriate DIM ‘A’ length from Table 5 based on where the cable clamp will be installed on the bracket, measure out this length from the factory breakout on the cable, and mark the cable at this location as shown in Figure 40. This is where the cable clamp should be placed on the cable.

c. If the cable being installed is designated for the splice chassis, obtain the appropriate

DIM ‘A’ length from Table 5 based on where the cable clamp will be installed on the bracket, and measure an additional length of 210 in. (533.4 cm), as shown in

Figure 41. This is where the cable clamp should be placed on the cable. For cable

routing instructions, refer to NG4access ODF Platform Splice Chassis and Splice Tray User Manual (TECP-90-704).

8. If the cable diameter is 0.8 in (2.0 cm) or less, assemble the “standard” cable clamp at the cable clamp position (see Figure 42). There are different sizes of grommets, measured by their inside diameters of 0.4, 0.5, 0.6, and 0.7 in. (1.0, 1.27, 1.52, and 1.78 cm). Select the grommet with an inside diameter that is one size smaller than the outside diameter of the cable. After assembling the components on the mounting screws, tighten the screws until the yokes make contact, then tighten the screws four additional revolutions.
