Physical Specifications

Use the physical specifications in Table 2-3 to plan the location of your array.

Layout Map

It is helpful to create a sketch or layout map to indicate the exact location of the array 
as well as the location of the hosts, console, and Ethernet connections that will be 
connected to it. 

As you lay out the components, consider the cable lengths that will be used. 

2.6.1

Rack Placement

Follow these guidelines when preparing a rackmount placement for your system:

■

Ensure that the floor surface is level.

■

Leave enough space in front of the rack to access components for servicing.

■

Leave enough space in back of the rack to access components for servicing. 

■

Keep power and interface cables clear of foot traffic. Route cables inside walls, 
under the floor, through the ceiling, or in protective channels or raceways.
