Tabletop or Shelf Installation

4.3TABLETOP OR SHELF INSTALLATION

This section provides guidelines for installation on a tabletop or shelf.

Tabletop and shelf installations must be within reach of the network cabling and meet the requirements listed below:

In a shelf installation, the shelf must be able to support 30 pounds of static weight for each device in the stack.

Maintain a temperature of between 5°C (41°F) and 40°C (104°F) at the installation site with fluctuations of less than 10°C per hour.

The SEHI must be located within seven feet of its power source and with an unrestricted free surface area as shown in Figure 4-2.

In order to allow for proper cooling, there must be a two-inch

!clearance on either side and the back of the unit.
