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

SRX3400 Services Gateway Routing Engine
The Routing Engine is a PowerPC platform that runs the Junos operating system (Junos
OS). Software processes that run on the Routing Engine maintain the routing tables,
manage the routing protocols used on the services gateway, control the services gateway
interfaces, control some chassis components, and provide the interface for system
management and user access to the services gateway.
Two USB ports on the Routing Engine accept USB memory cards that allow you to load
Junos OS and perform file transfers.
The Routing Engine also provides the following integrated services:
•
Central Packet Forwarding Engine Processing (CPP)—This service manages all CFM
cards.
• System Control—This service handles Routing Engine arbitration and switching between
multiple control planes and acts as the host for the Switch Fabric Board (SFB) and
midplane components.
