Installing the Hub

Installation

The site where you install the hub stack may greatly affect its performance. When installing, consider the following pointers:

Install the hub stack in a fairly cool and dry place. See Appendix B, Specifications, for the acceptable temperature and humidity operat- ing ranges.

Install the hub stack in a site free from strong electromagnetic field generators (such as motors), vibration, dust, and direct exposure to sunlight.

Leave at least 10cm of space at the front and rear of the hub for ventilation.

Install the hub on a sturdy, level surface that can support its weight.

When installing the hub stack on a level surface, attach the rubber feet to the bottom of each device. The rubber feet cushion the hub and protect the hub case from scratches and prevent it from scratching other surfaces.
