Juniper Networks J-series Services Router J2320 - Manual (Page 68)

Field-Replaceable PIMs
PIMs are removable and insertable only when the Services Router is powered off.
You can install a PIM into one of the slots in the router chassis. If a slot is not occupied
by a PIM, a PIM blank panel must be installed to shield the empty slot and to allow
cooling air to circulate properly through the router.

J2320 and J2350 Field-Replaceable PIM Summary
Table 19 on page 47 provides software release information, port numbers, and
sample interface names for the field-replaceable PIMs supported on J2320 and J2350
Services Routers. The supported PIMs can be installed in any slot available on the
J2320 and J2350 routers.
CAUTION: Do not install a combination of PIMs in a single chassis that exceeds the
maximum power and heat capacity of the chassis. If J-series power management is
enabled, PIMs that exceed the maximum power and heat capacity remain offline
when the chassis is powered on.
To verify that the combination of PIMs to be installed in a chassis does not exceed
the power and heat capacities for the J2320 or J2350 router, see “Planning for Power
Management” on page 112.
NOTE: Although J2320 and J2350 Services Routers support PIMs that were introduced
before the JUNOS 8.4 release, these routers do not support software releases earlier
than JUNOS 8.4.
