Step 3:

Adjust the kit location in the Z direction (forwards or backwards) so the housing will align with the

front of the cabinet below, if present. Consider the 4.5-in frontal projection in your calculations.

Tighten the screws on the underside of the mini-frame.

NOTE: Calculate these dimensions carefully. Once the housing is installed, any adjustment needed along the Z

axis will require that the housing be removed.

TPA-5836

Step 4: Once the kit is secured in position, install the EDGE™ housing, as applicable, or any other device that

has the ability to be installed into a 19-in rack space. Slide the housing over the support bars into the

mounting kit. The bars will hold the housing while securing the mounting brackets on each side into

the mounting holes on front of the kit. If installing only one housing, place it in the top position.

NOTE: If the lowest housing is not supported by the support bars, remove and reinstall the support bars directly

below the housing as described in Section 4.

(OPTIONAL) Install CDF Bracket

An optional CDF bracket may be installed external to the housing on the frame to provide additional cable

trunk installation positions and/or strain-relief. It supports incoming cable installation from the top or bottom

of the frame into the housing. The bracket can hold keyhole cradles or U-clip furcation trunk holders (ordered

separately) and is available in three sizes:

• EDGE-CDF-RJ04-BKT — 4-position furcation trunk holder

• EDGE-CDF-RJ08-BKT — 8-position furcation trunk holder

• EDGE-CDF-RJ12-BKT — 12-position furcation trunk holder

CDF brackets support use of extender trunks. If using an IBU (vertical manager) between frames, extender

trunks mounted to the CDF bracket on the back side of the frame must transition to the front using a "pass-

through" IBU system.

Step 1:

Align bracket within the same height of the 4U housing.

Step 2:

Install bracket using two 12-24 screws (Figure 6). Allow enough clearance when routing trunks from

the bracket into the housing to ensure bend radius is maintained when trunks enter the housing.

NOTE: If greater bend radius control of cable is required, position the bracket slightly above or below the roof of

the housing, depending upon the direction the cable is entering the housing.

Step 3:

Insert furcation plug into cradle as seen in Figure 7 and mount cradle onto CDF bracket.
