PIC activation on high-end SRX services gateways may be different from common request chassis ... online/offline. It depends on the choice of FPC (Flexible PIC Concentrator) cards, aka line interface card in Cisco. Some FPCs do not support having all PICs (Physical Interface Cards) online due to power/capacity restrictions, hence the need to sacrifice certain PICs by bringing them offline while enabling other PICs.
Let’s take a look at FPC in slot 5:
root> show chassis fpc pic-status

--------------------------------------------------------------------------
Slot 0 Online SPC3
PIC 0 Online SPU Cp-Flow
PIC 1 Online SPU Flow
Slot 1 Online SPC3
PIC 0 Online SPU Flow
PIC 1 Online SPU Flow
Slot 5 Online SRX5k IOC3 24XGE+6XLG
PIC 0 Online 12x 10GE SFP+
PIC 1 Online 12x 10GE SFP+
PIC 2 Offline 3x 40GE QSFP+
PIC 3 Offline 3x 40GE QSFP+
FPC in slot 5 supports only 2xPICs functioning at the same time. The default state is PIC0 & PIC1 are online and PIC2 & PIC3 are offline. To enable PIC0 and PIC3 we must explicitly disable PIC1 & PIC2. There is no ON option. The SRX will treat whetever is not “off” as “on”.
NOTE
There are restrictions on combinations of PICs which can be enabled on a particular FPC. Read specific FPC datasheet for details.
