SRX3600 Services Gateway NP-IOCs
Network Processing I/O Cards (NP-IOCs) are IOCs designed specifically for low-latency applications. Each
NP-IOC has its own network processing unit (NPU), so that traffic traversing the NP-IOC does not have
to traverse the services gateway bus to a remote network processing card (NPC). It is inserted horizontally
into the midplane of the services gateway to communicate with the Switch Fabric Board (SFB) and to
receive power. Figure 6 on page 17 shows a typical NP-IOC.

NOTE: You can install NP-IOCs instead of NPCs and IOCs in the services gateway. However, if no
NPCs are present, the Ethernet ports on the SFB will not be functional.
For detailed information about the NP-IOCs supported by the services gateway, see the SRX1400, SRX3400,
and SRX3600 Services Gateway Module Guide at www.juniper.net/documentation/.
