The cooling system in an EX6210 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
six fans, three rows of two fans each.
The fan tray installs vertically on the right side on the rear of the chassis and provides
front-to-back chassis cooling. Two handles, one handle on the top and one on the bottom
of the front faceplate facilitates handling of the fan tray. See
