IOCs and NP-IOCs Supported on the SRX1400 Services Gateway


I/O cards (IOCs) are common form-factor module (CFM) cards that provide additional physical network connections to the services gateway. Their primary function is to deliver data packets arriving on the physical ports to the Network and Services Processing Card (NSPC) and to forward data packets out the physical ports after services processing.

Network Processing I/O cards are IOCs that have their own Network Processing Units (NPUs) so that traffic traversing the NP-IOC does not have to traverse the services gateway bus to a remote NPC. They are well suited to low-latency applications.

You can install one IOC or NP-IOC in the CFM 2 of the SRX1400 Services Gateway. If no CFM card is installed in slot 2, you must install a blank panel to shield the empty slot and to allow cooling air to circulate properly through the services gateway.

For detailed information about the IOCs and NP-IOCs supported by the services gateway, see the SRX1400, SRX3400, and SRX3600 Services Gateway Module Guide   at


IOCs are not provided with the SRX1400 Services Gateway. You must order them separately. Contact your Juniper Networks customer service representative for more information.
