SRX3600 Services Gateway Routing Engine

The Routing Engine is a PowerPC platform that runs the 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 the Junos OS and perform file transfers.

The Routing Engine also provides the following integrated services:

The services gateway must have one Routing Engine installed in slot RE0. A Gigabit Ethernet port on the front panel of the Switch Fabric Board (SFB) is connected directly to the processors on the REs for management purposes. The SFB port labeled RE ETHERNET 0 connects to the Routing Engine in slot RE0.

Note: Unless you have installed an SRX Clustering Module (SCM) in slot RE1, the empty RE1 slot should have a blank panel installed to shield it and to allow cooling air to circulate properly through the services gateway.
