SRX3400 Services Gateway Routing Engine

The Routing Engine (RE) is a PowerPC platform that runs the JUNOS Software. Software processes that run on the Routing Engine maintain the routing tables, manage the routing protocols used on the device, control the device interfaces, control some chassis components, and provide the interface for system management and user access to the device.

A pair of USB ports on the Routing Engine accept USB memory cards that allow you to load the JUNOS Software and perform file transfers.

The Routing Engine (RE) also provides the following integrated services:

The Services Gateway must have one RE installed in slot RE0. Two Gigabit Ethernet ports on the front panel of the Switch Fabric Board (SFB) are connected directly to the processors on the REs for management purposes. The SFB port labeled RE ETHERNET 0 connects to the RE0 Routing Engine slot and the RE ETHERNET 1 port connects with slot RE1.

Note: The RE1 slot should have a blank panel installed to shield the empty slot and to allow cooling air to circulate properly through the device.
