M320 PIC Description on page 54
In most cases, you can install PICs of different media types on the same FPC as long as
the FPC and the router support those PICs. However, configuration rules might limit
certain combinations of PICs on some platforms.
Newer Junos OS services for some PICs can require significant Internet Processor ASIC
memory. Ethernet and SONET PICs typically do not use large amounts of memory. Gigabit
Ethernet, ATM2, IQ serial PICs, and Multiservices PICs use more. To conserve memory,
you can group PICs in the same family together on the same FPC.
If you have different PIC families on a single FPC, review the configuration rules to plan
which PICs to install on the FPCs for your router. Consult technical bulletin
for information about configuration rules for PIC combinations on the

When you upgrade to Junos OS Release 7.5 or later, a warning appears if any configuration
rules affect your PIC combinations. If you continue the installation, one or more PICs
might appear to be online (the LEDs are on), but the Junos OS cannot enable them and
they cannot pass traffic. As a workaround, you can:
Install a Junos OS release that supports the combination.
Install PICs on a different FPC.
Remove PICs from the affected FPC.

The PIC/FPC compatibility matrixes list the first Junos OS Release in which an FPC
supports each PIC currently supported for the M320 router. For example, Junos OS Release
7.5 is the first release in which the E-II-FPC1 supports the ATM2 OC3/STM1 IQ, 2-port PIC.
