Site Selection
Describes the location specifications.
Consider the following criteria 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. Thre following figure displays switch clearance requirements.
Figure 1: Switch Component Removal Footprint
1. 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 40°C (104°F).
Pour empêcher l'interrupteur de surchauffe, ne pas utiliser il dans une zone où la
température ambiante est supérieure à 40°C (104°F).
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.
displays power supply module locations on the front panel.
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.
•
All front panel modules have the same color handles.
•
Rear panel modules must have different color handles than front panel modules.
Orient the switch to assure that the air intake modules face the cool aisle. If the airflow direction is
not compatible with the installation site, contact your sales representative to obtain modules that
circulate air in the opposite direction.
•
Rack Space: Install the switch in a 19" rack or cabinet. The switch height depends on the switch
model, as specified in
Table 1: 7300 Modular Switch and Component Specifications
. Verify that
the linecard and supervisor removal clearance (
Figure 1: Switch Component Removal Footprint
provide adequate space for the power and data cables that connect to the switch.
