QFX10000 Field-Replaceable Units

Field-replaceable units (FRUs) are switch components that you can replace at your site. The switch uses these types of FRUs:

Hot-insertable and hot-removable—You can remove and replace these components without powering off the switch or disrupting the switching function.
Hot-pluggable—You can remove and replace these components without powering off the switch, but the switching function is interrupted until you replace the component.

Table 1 lists the FRUs and their types for the QFX10000.

Table 1: FRUs in an QFX10000
FRU	Type
Power supplies	Hot-insertable and hot-removable.
Fan tray	Hot-insertable and hot-removable.
Fan tray controller	Hot-insertable and hot-removable.
Routing Control Board (RCB)	Redundant configuration: Primary RCB is hot-pluggable. Backup RCB is hot-insertable and hot-removable. Base configuration: Removal of the RCB will cause the switch to shut down. You can install a replacement RCB in the second slot. The system will restart to elect a primary and backup. If necessary, you can switch the primary and backup using the `request chassis routing-engine master switch` command. See QFX10008 Configurations and Upgrade Options and QFX10016 Components and Configurations.
Switch Interface Boards (SIBs)	SIBs are hot-insertable and hot-removable. We recommend that you take SIBs offline before removing them to avoid traffic loss while the switch fabric is being reconfigured. For example: user@switch> `request chassis sib (offline \| online) slot slot-number offline`
Line cards	Hot-insertable and hot-removable. We recommend that you take line cards offline before removing them. For example: user@switch> `request chassis fpc slot slot-number offline`
Optical transceivers See the Hardware Compatibility Tool.	Hot-insertable and hot-removable.

Note:

Line cards are not part of the base or redundant configuration. You must order them separately.

Note:

If you have a Juniper Care service contract, register any addition, change, or upgrade of hardware components at https://www.juniper.net/customers/support/tools/updateinstallbase/. Failure to do so can result in significant delays if you need replacement parts. This note does not apply if you replace an existing component with the same type of component.
