•    Four M6 mounting screws and four cage nuts

•    Optical patch cords

•    Cable ties

Rack-mounting the unit

Perform the following steps to install a standalone unit into the rack:

1. Depending on the access requirements, decide which side you want to use as the front side in the rack. For better cable management, ensure that the side chosen for the unit is same as that of the node in the rack.

2.     Determine the positioning of the unit in the rack and the rack holes to be used for mounting. Ensure that 1RU space is available in the rack.

NOTE: TJ1600-2 passive unit requires 1.5RU height.

3.     Do the suitable step of the following:

—    If the rack holes are un-threaded but have bolt attached on rear side of the hole, then directly go to step 4.

—    If the rack holes are square and un-threaded, attach four cage nuts over the holes in the rack post as shown in the following figure. Two cage nuts on rear side of the holes on each rack post.

Figure 270: Install the cage nut on the rack post

4.     Move the unit to the desired rack position.
