The SRX Clustering Module (SCM) is a card that you can install in service gateways to enable redundant control links in high availability clusters. It is a behavior of request system halt installed in SRX-3400 and SRX-3600 devices. The presence of CRM can be found by the output of chassis hardware. When a CRM is placed in SRX-3400 or SSX-3600 device, the SRX detects the CRM as a new routing engine then gives an option for the system halt with both routing engines. This is because of the initially the SRX was designed to have the dual routing engines but it is not supported so the system halt command without both routing engines used as there is no RE in the CRM.
