Chapter 2 shows the location of the System Controller’s front panel on the
chassis. Figure 3-4 in Chapter 3 identifies its related control buttons. To

Controller” in Chapter 5.
Operating Considerations
This section covers the basic requirements for physical location to ensure
proper chassis operation.
The Challenge deskside chassis is designed to fit into a typical work
environment. Keep the system in good condition by maintaining the
following operating conditions:
• The chassis should ideally have a 6-inch (15-cm) minimum air clearance
above the top. The first line of Table 1-1 shows the side clearances
required. If the chassis is positioned under a desk or other equipment
and the top air clearance is less than 6 inches (15 cm), make sure that
the side air clearances are at least as great as those listed on the second
line of Table 1-1.
• The chassis should be kept in a clean, dust-free location to reduce
maintenance problems.
• The available power should be rated for computer operation.
• The chassis should be protected from harsh environments that produce
excessive vibration, heat, and similar conditions.
