Installing the Mounting Ears
The Calix E5-400 unit includes two sets of shelf mounting ears (19 and 23-inch rack sizes).
To rack mount the unit, you must install the appropriate mounting ears for your rack
requirements.
To install the mounting ears
1. Measure the width of the equipment rack where the E5-400 unit will be installed.
Note: If the overall width exceeds 24-inches, it is a 23-inch rack. If the outer width
exceeds 20-inches, it is a 19-inch rack.
2. Get the appropriate pair of mounting ears and (8) flat head screws from the kit.
3. Secure the mounting ears to the side of the E5-400 unit (four screws per side) as shown.
Note: This unit is equipped with three positions for placement of mounting ears, to
support front and mid-mount rack installation depths. For front mount deployments, use
the first or second positions (forward sets of four holes). For mid-mount deployments,
use the third position (back set of four holes).
