Mounting the Brackets on NCS 2006 Shelf

This chapter explains how to mount the brackets on Cisco NCS 2006 shelf.


Caution

Use only the fastening hardware provided with the NCS 2006 shelf to prevent loosening, deterioration, and electromechanical corrosion of the hardware and joined material.


Caution

When mounting the NCS 2006 shelf in a frame with a nonconductive coating (such as paint, lacquer, or enamel) either use the thread-forming screws provided with the NCS 2006 shipping kit, or remove the coating from the threads to ensure electrical continuity.

The reversible mounting bracket is used to mount the shelf on a 19-inch or 23-inch (482.6 mm or 584.2 mm) rack.

Warning

This product relies on the building’s installation for short-circuit (overcurrent) protection. Ensure that the protective device is rated not greater than: 40A and between -40.5 VDC to -57.6 VDC. Statement 1005


Warning

This product relies on the building's installation for short-circuit (overcurrent) protection. Ensure that the protective device is rated not greater than: 10A-20A, 100-240 VAC~. Statement 1005


Warning

To prevent the system from overheating, do not operate it in an area that exceeds the maximum recommended ambient temperature of: 131°F (55°C). Statement 1047


Warning

Take care when connecting units to the supply circuit so that wiring is not overloaded. Statement 1018


Warning
To prevent bodily injury when mounting or servicing this unit in a rack, you must take special precautions to ensure that the system remains stable. The following guidelines are provided to ensure your safety:
  • This unit should be mounted at the bottom of the rack if it is the only unit in the rack.
  • When mounting this unit in a partially filled rack, load the rack from the bottom to the top with the heaviest component at the bottom of the rack.
  • If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the unit in the rack. Statement 1006

Warning

To prevent airflow restriction, allow clearance around the ventilation openings to be at least:1 inch (25.4 mm). Statement 1076


Warning

To comply with EN50121-4:2006 - Railway applications, Electromagnetic compatibility, a shielded cable must be used to connect to the EMS port. This cable must be less than 30 meters in length and not placed in the 3 meter boundary, as defined in EN50121-4:2006, Table 2, note 1. Statement 8010


Warning

To comply with EN50121-4:2006 - Railway applications, Electromagnetic compatibility, DC power cables must be less than 30 meter long. Statement 8011


Note
During installation, do not use the door to handle the chassis.

Note
Remove the door from the NCS 2006 shelf and reinstall it after installing all the other modules.
