ACX7509 Cable Management System Maintenance

Maintaining an ACX7509 router includes installing and removing the cable management system properly.

The ACX7509 cable management system organizes and protects optical cabling attached to the Routing and Control Boards (RCBs) and Flexible PIC Concentrator (FPC).

The cable management system consists of the following components:

  • Left and right side covers

  • Fiber management tray

  • Cable manager door

  • Air filter door

Install the ACX7509 Cable Management System

Ensure that you have the following parts and tools available to install the ACX7509 cable management system:

  • Phillips (+) screwdriver, number 2

  • Eight mounting screws (provided)

  • Electrostatic discharge (ESD) grounding strap to wrap around your bare wrist and connect to an ESD point on the chassis

To install the cable management system:

  1. Wrap and fasten one end of the ESD wrist strap around your bare wrist, and connect the other end of the strap to the ESD point on the device.
  2. Position the fiber management tray below the ACX7509 chassis, and align its mounting brackets holes with the holes of the rack rails.
  3. Install mounting screws into each of the mounting bracket holes aligned with the rack, starting from the bottom, and tighten the screws. See Figure 1.

  4. Remove the top and bottom chassis mounting screws.
  5. Rest the left and right side covers on the fiber management tray.
  6. Slide the side covers until the side cover brackets contact the front mounting brackets of the ACX7509 chassis and the shoulder pins on the side covers are guided into the brackets on the fiber management tray.
  7. Install back the top and bottom chassis mounting screws and tighten the screws. See Figure 2.
