Installing the SEHI

4.3.1Tabletop 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:

A single phase grounded power receptacle that meets the power supply requirements listed in Chapter 3 under Power Supply Requirements must be located within seven feet of the location.

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 site with fluctuations of less than 10°C (18°F) per hour.

For a tabletop or shelf installation, locate the SEHI 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.
