The cooling system in an MX10008 chassis consists of two fan trays and two fan tray controllers, which
are hot-insertable and hot-removable field replaceable units (FRUs).
There are two cooling system configurations available:
JNP10008-FAN and JNP10008-FAN-CTRL—Designed to support the standard or enhanced power bus
and power supplies JNP10K-PWR-AC and JNP10K-PWR-DC
JNP10008-FAN2 and JNP10008-FTC2—Designed to support both the standard or enhanced power
bus and all power supplies
WARNING: Use only the fan tray designed for the matching fan tray controller.
To determine which chassis you have, see
Fan Trays
Each fan tray contains 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
