Using this fiber optic rack mount enclosure is easy. First, find a suitable spot in your rack to install it. Make sure the area has enough space for the 19 - inch width, 12 - inch depth, and 5.25 - inch height of the enclosure. When you're ready, attach it to the rack using the provided rack ears. As for maintenance, keep the enclosure clean. You can use a soft, dry cloth to wipe off any dust. Be careful not to scratch the surface.
