Removing an MX10008 Fan Tray
An MX10008 has two independent, field-replaceable fan trays. Each fan tray is a hot-removable and
hot-insertable field-replaceable unit (FRU); you can remove and replace the fan tray while the router is
running without turning off power to the router or disrupting routing functions. There are two models of
the fan tray, JNP10008-FAN and JNP10008-FAN2.
CAUTION: Do not remove the fan tray unless you have a replacement fan tray available.
Each fan tray is installed vertically on the rear, or FRU-side, of the chassis.
