Do not install Type 2 IQE PICs in both PIC slot number 2 and PIC slot number 3 of the M120-FPC2. You can install one 4-port Channelized OC12/STM4 IQE PIC or one 1-port Channelized OC48/STM4 IQE PIC into either PIC slot number 2 or PIC slot number 3. In the other slot, you can install any Type 2 PIC except the 8-port Gigabit Ethernet IQ2 PIC or 8-port Gigabit Ethernet IQ2E PIC.
