Services Routers Hardware Guide

Field-Replaceable PIMs
PIMs are removable and insertable only when the Services Router is powered off.
You install PIMs into 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 and Module Summary
Table 19 on page 39 provides software release information, port numbers, and
sample interface names for the field-replaceable PIMs and modules supported on
J2320 and J2350 Services Routers. For interface naming conventions, see the JUNOS
Software Interfaces and Routing Configuration Guide. The supported PIMs can be
installed in any slot available on the J2320 and J2350 routers. The WXC Integrated
Services Module supported on the J2350 model occupies two slots. You can install
only one of these modules in a router chassis.
CAUTION: Do not install a combination of modules in a single chassis that exceeds
the maximum power and heat capacity of the chassis. If J-series power management
is enabled, PIMs and modules (PIMs or PIMs plus a WXC Integrated Services Module)
that exceed the maximum power and heat capacity remain offline when the chassis
is powered on.
To verify that the combination of modules to be installed in a chassis does not exceed
the power and heat capacities for the router, see “Planning for Power
Management” on page 72.
