Field-Replaceable Units in an EX8208 Switch
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 for the EX8208 switch and their types.
Table 1: FRUs in an EX8208 Switch
FRU | Type |
|---|---|
Power supplies | Hot-insertable and hot-removable. |
Fan tray | Hot-insertable and hot-removable. |
Switch Fabric and Routing Engine (SRE) module | Redundant configuration:
Base configuration:
|
Switch Fabric (SF) module | Redundant configuration:
Base configuration:
|
8-port SFP+ line card 40-port SFP+ line card 48-port SFP line card 48-port RJ-45 line card | Hot-insertable and hot-removable. We recommend that you take the line cards offline before removing them. See Removing a Line Card from an EX8200 Switch. |
SFP and SFP+ transceivers | 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 J-Care service contract, register any addition, change, or upgrade of hardware components at https://www.juniper.net/customers/csc/management/updateinstallbase.jsp. Failure to do so can result in significant delays if you need replacement parts. This note applies if you add a new type of line card. It does not apply if you replace these components with the same type of component. |
