Cooling System and Airflow in a J-EX8208 Switch
The cooling system in a J-EX8208 switch consists of a single fan tray. The fan tray is a
hot-insertable and hot-removable field-replaceable unit (FRU). The fan tray contains 12
fans.
The fan tray installs vertically on the left side on the front of the chassis and provides
side-to-side chassis cooling. A handle on the front faceplate facilitates handling of the
fan tray. See Figure 24 on page 39.
