3 Installing Subracks
Usually OptiX OSN 8800 T32/T16 and
universal platform
subracks are also pre-installed in cabinets, and they are
delivered separately only for network expansion. That is, OptiX OSN 8800 T32/T16 and
universal platform
subracks
usually need onsite installation in a network expansion scenario.
1. For safety concern, at least two persons are required to install the subrack. One person is to hold the subrack and the
other person to tighten the panel screws.
2. To deploy T64 and other subracks or T32 and other subracks inside the same cabinet, install them from top to bottom
and front to rear. To deploy T16 subracks or a mix of T16 and universal platform subracks inside a cabinet that has an
electrical subrack pre-installed, install them below the electrical subrack from top to bottom. If the cabinet has no
electrical subrack pre-installed, install them from bottom to top. In any other scenarios, install the subracks (either all
T16 subracks or a mix of T16 and universal platform subracks) from bottom to top.
3. Generally, floating nuts has been installed on the cabinet columns. Therefore, you can directly install a subrack in a
cabinet for network expansion.
4. Before installing a subrack, remove the package of the cables that are bundled inside the cabinet, and then bundle the
cables tidily.
5. Ground cables for subracks have already been installed in a cabinet before delivery. If a subrack is separately
delivered, unpack the ground cable and connect one end of the cable to the subrack ground point. After that, secure the
subrack.
An OptiX OSN 8800 T64 subrack is pre-installed in an N66B cabinet. Remember that human safety is paramount.
Protect yourself at all times, especially when lifting or transporting the cabinet.

1. The T32 subrack is installed in the same way
as the T16 subrack is installed.
2. To deploy four universal platform subracks
in the same cabinet, install them in the same
way as you install the T16 subrack.
3. The figure on the left uses installing a T16
subrack as an example.
