Field-Replaceable Units on the SRX3600 Services Gateway

Field-replaceable units (FRUs) are services gateway components that can be replaced at the customer site. The services gateway uses the following types of FRUs:

Hot-swappable FRUs—You can remove and replace these components without powering off the services gateway or disrupting the routing functions.
Cold-swap-only FRUs—You must power off the services gateway in order to remove, replace, or add these components.

Table 1 lists the FRUs for the services gateway.
