M7i PIC Combination Limitations
In most cases, you can install PICs of different media types in the M7i router. However,
configuration rules might limit certain combinations of PICs. Some PICs of different PIC
families cannot be installed in PIC slots 0 and 1, or in slots 2 and 3. If you have different
PIC families in the M7i router and are running Junos OS Release 10.2 or later, review the
configuration rules to plan which PICs to install in your router. Consult technical bulletin
PSN-2007-01-023 on the Juniper Networks Support site at
https://www.juniper.net/support/ for information about configuration rules for PIC
combinations.
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, IQE PICs, and Multiservices PICs use more. To conserve
memory, you can group PICs in the same family together on the same router.
As a workaround, you can:
•
Install one PIC in a different PIC slot.
•
Remove one of the PICs from the router

M7i PIC/CFEB Compatibility
The PIC/CFEB compatibility matrixes list the current PICs for the M7i router. For example,
Junos OS Release 9.4 is the first release in which the CFEB-E supports the ATM2 DS3 IQ
PIC.
