Summary of Contents for Cisco ONS 15454

  • Page 1 C H A P T E R Install the Shelf and Backplane Cable This chapter provides procedures for installing the Cisco ONS 15454. To view a summary of the tools and equipment required for installation, see the “Required Tools and Equipment” section on page 1-2.

  • Page 2: Included Materials

    Only trained and qualified personnel should be allowed to install, replace, or service this equipment. Warning The ONS 15454 is intended for installation in restricted access areas. A restricted access area is Warning where access can only be gained by service personnel through the use of a special tool, lock, key, or other means of security.

  • Page 3: User-Supplied Materials

    Install the Shelf and Backplane Cable Required Tools and Equipment User-Supplied Materials The following materials and tools are required but are not supplied with the ONS 15454: One or more of the following equipment racks: • 19-inch (482.6 mm) rack; total width 22 inches (558.8 mm) –...

  • Page 4: Test Equipment

    None Step 1 When you receive the ONS 15454 system equipment at the installation site, open the top of the box. The Cisco Systems logo designates the top of the box. Remove the foam inserts from the box. The box contains the 15454 shelf (wrapped in plastic) and a Step 2 smaller box of items needed for installation.
  • Page 5 Pins are not bent or broken. • Frame is not bent. • If the pins are bent or broken, or the frame is bent, call your Cisco sales engineer for a replacement. Step 3 Close the front door before installing. Step 4 Return to your originating procedure (NTP).
  • Page 6 Warning shelf assembly. The ONS 15454 must have 1 inch of airspace below the installed shelf assembly to allow air flow to Warning the fan intake. The air ramp (the angled piece of sheet metal on top of the shelf assembly) provides this spacing and should not be modified in any way.
  • Page 7 Caution electromechanical corrosion of the hardware and joined material. When mounting the ONS 15454 in a frame with a nonconductive coating (such as paint, lacquer, or Caution enamel) either use the thread-forming screws provided with the ONS 15454 shipping kit, or remove the coating from the threads to ensure electrical continuity.
  • Page 8 Each bracket has a filter stopper and a flange on one end. Make sure to attach the brackets with the stoppers and flanges facing the rear of the shelf assembly (the top, if the ONS 15454 is face-down during installation).
  • Page 9 If installing the 15454-SA-NEBS3 shelf assembly, a standard 80-A fuse panel (20-A fuse per shelf minimum) is required. Step 2 Ensure that the shelf assembly is set for the desired rack size (either 23 inches [584.2 mm] or 19 inches [482.6 mm]). Cisco ONS 15454 Procedure Guide, R4.0 March 2003...
  • Page 10 Step 6 When the shelf assembly is secured to the rack, install the remaining mounting screws. Step 7 Use at least one set of the horizontal screw slots on the ONS 15454 to prevent slippage. Note Remove the temporary set screws.
  • Page 11 The ONS 15454 must have one inch (25.4 mm) of airspace below the installed shelf assembly to allow Note air flow to the fan intake. If a second ONS 15454 is installed underneath a shelf assembly, the air ramp on top of the bottom shelf assembly provides the desired space. However, if the ONS 15454 is installed above third-party equipment, you must provide a minimum spacing of one inch (25.4 mm) between the...
  • Page 12 Security Level None The ONS 15454 has an ESD plug input and is shipped with an ESD wrist strap. The ESD plug input is Note located on the outside edge of the shelf assembly on the right-hand side. It is labeled “ESD” on the top and bottom.
  • Page 13 To detach the ground strap from the front door, loosen the #6 kep nut (49-0600-01) using the open-end wrench. Detach the end of the ground strap terminal lug (72-3622-01) from the male stud on the inside of the door. Cisco ONS 15454 Procedure Guide, R4.0 1-13 March 2003...
