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.

If the installation requires that the SEHI is to be stacked, proceed to 
Section 4.3.3. Otherwise, continue by connecting power as described in 
Section 4.4.

In order to allow for proper cooling, there must be a two-inch 
clearance on either side and the back of the unit.
