Remove a PTX10004 Fan Tray
The PTX10004 chassis has two independent, field-replaceable fan trays (JNP10004-FAN2). Each fan tray
is a hot-removable and hot-insertable FRU; you can remove and replace a single fan tray while the router
is running without turning off power to the router or disrupting routing functions.
CAUTION:
If you remove a fan tray, you have a limited amount of time before a thermal alarm is raised. If you plan
to replace one or more JNP10004-SF3 Switch Interface Boards (SIBS), make sure you calculate the
round-trip of removing the fan tray, adding or replacing the SIBS, and installing the fan tray back into the
chassis. To calculate the time allowed for replacing a fan tray, see
Do not remove the fan tray unless you have a replacement fan tray available.
