Stand the cabinet door, insert the lower rotating 
shaft into the alignment hole of the cabinet, pull 
down the upper lever of the cabinet door, and 
insert the upper rotating shaft into the alignment 
hole of the cabinet.

1. Ensure that no optical fiber protrudes from the 
side panel. Then slowly open and close the front 
door to check whether there is a risk of fiber 
clamping and complete the fiber routing 
acceptance.
2. For information about how to install the doors of 
the N63B cabinet, see the

Installation Guide

.

3. The cabinet holding the subrack has one air 
filter installed on the interior side of the cabinet
