The PTX10004 cooling system components work together to keep all components within the acceptable
temperature range. If the maximum temperature specification is exceeded and the system cannot be
adequately cooled, the Routing and Control Board (RCB) shuts down some or all of the hardware
components.

The cooling system in a PTX10004 chassis consists of dual fan trays (JNP10004-FAN2) with matching
dual fan tray controllers (JNP10004-FTC2). Each fan tray requires a companion fan tray controller to be
installed and operational to be hot-insertable and hot-removable.
Fan Tray
The JNP10004-FAN2 fan tray contains an array of internal fans, a non-removable control board, and LEDs.
The two fan trays install vertically, side by side, next to the power supplies on the FRU side of the chassis.
Two handles on each front faceplate facilitate handling of the fan tray. See
