1.11 Cable Routing and Management
The ONS 15454 cable management facilities include the following:
• A cable-routing channel (behind the fold-down door) that runs the width of the shelf assembly
(Figure 1-32)
• Plastic horseshoe-shaped fiber guides at each side opening of the cable-routing channel that ensure
the proper bend radius is maintained in the fibers (Figure 1-33)
Note You can remove the fiber guide if necessary to create a larger opening (if you need to route
CAT-5 Ethernet cables out the side, for example). To remove the fiber guide, take out the
three screws that anchor it to the side of the shelf assembly.
• A fold-down door that provides access to the cable-management tray
• Cable tie-wrap facilities on EIAs that secure cables to the cover panel
• A cable routing channel that enables you to route cables out either side
• Jumper slack storage reels (2) on each side panel that reduce the amount of slack in cables that are
connected to other devices
Note To remove the jumper slack storage reels, take out the screw in the center of each reel.
• Optional tie-down bar
Figure 1-32 shows the cable management facilities that you can access through the fold-down front door,
including the cable-routing channel and cable-routing channel posts.
