Figure 174: Cisco ONS 15454 M6 Shelf Dimensions for an ETSI Rack Configuration
The standard ETSI racks can hold seven ONS 15454 M6 shelves. When mounting a shelf 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. Caution
Mounting a Single Node
The ONS 15454 M6 requires 264.16 mm (10.4-inches) minimum of vertical rack space. To ensure the mounting
is secure, use two to three M6 mounting screws for each side of the shelf. A shelf should be mounted at the
bottom of the rack if it is the only unit in the rack.
In an ETSI rack, the brackets are mounted only in the front position.
If the ONS 15454 M6 shelf is fully loaded, then two people should install it. However, it is possible for one
person to install an empty shelf. The shelf should be empty for easier lifting. For information on the ONS
15454 M6 shelf weight, see the
Dimensions, on page 479 .
