SRX650 Services Gateway Services and Routing Engine 6
The Services and Routing Engine (SRE) module provides processing power for security
services, routing protocol processes, and other software processes that control the
services gateway interfaces, some of the chassis components, system management,
and user access to the device.
The services gateway must have one SRE installed.
CAUTION: The SRE is not hot-swappable. You must power off the services
gateway before removing or inserting an SRE.
The SRE installs horizontally in the back of the chassis in slots SRE0 or SRE1/SRE1.1. An
SRE weighs 3 lb 13.6 oz (1.75 kg).
NOTE: Slot SRE0 is a full-length slot capable of holding a full slot module
such as an SRE. The SRE1 and SRE1.1 slots are capable of holding either two
half slot modules or one full slot module.
If a slot is not occupied by a card, a blank panel must be installed to shield the empty
slot and to maintain proper cooling of the services gateway.
Figure 1 on page 12 shows the front of the SRE.
