SRX3400 Services Gateway SRX Clustering Module
The SRX Clustering Module (SCM) is a card that you can install in the services gateway to enable the dual control link feature for chassis cluster supported in JUNOS Release 10.2. You install the SCM in the RE1 slot on the rear panel of the services gateway. The SCM is shown in Figure 1.
Figure 1: SRX Clustering Module
 | Note: The services gateway must be running JUNOS Release 10.2 or later to use the SCM. When running earlier JUNOS releases, the services gateway does not properly recognize it. |
For more information about configuring and managing chassis clusters, see the chapter “Chassis Cluster” in the JUNOS Software Security Configuration Guide.
Table 1 describes the SCM behavior indicated by the LED on its front panel. The ONLINE button on the SCM front panel does not perform any function in the current software release.
