Field-Replaceable Units on the SRX3400 Services Gateway
Field-replaceable units (FRUs) are services gateway components that can be replaced at the customer site. The device uses the following types of FRUs:
- Hot-removable and hot-insertable FRUs—You can remove and replace these components without powering off the device or disrupting the routing functions.
- Cold-swap-only FRUs—You must power off the device in order to remove, replace, or add these components.
Table 1 lists the FRUs for the services gateway.
