Preparation
2.1 Site Selection
The following criteria should be considered when selecting a site to install the switch:
Floor Space: Install the switch in an area that provides adequate clearance for removing front and rear
components. Figure 2-1 displays switch clearance requirements.
Figure 2-1: Switch Component Removal Footprint
• Temperature and Ventilation: For proper ventilation, install the switch where there is ample
airflow to the front and back of the switch. The temperature should not go below 0° or exceed 40° C.
Important! To prevent the switch from overheating, do not operate it in an area where the ambient temperature
exceeds limits specified in
Table 1-1 on page 2 .
• Airflow Orientation: Determine airflow direction of the fan modules and power supply modules.
Fan and power supply module handles indicate airflow direction:
• Blue Handle : Air Inlet module.
• Red Handle : Air Exit module.
Appendix D displays power supply module locations on the front panel. Appendix E displays fan
module locations on the rear panel (DCS-7316 switches may also contain rear panel power supply
modules). Verify the airflow direction of all modules satisfy these criteria:
• All rear panel modules have the same color handles.
