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.

Line cards | 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 See Optical Interface Support in EX8200 Switches for the Junos OS release in which the transceivers were introduced. | 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 change the type of power supply from AC to DC or DC to AC or add a new type of line card. It does not apply if you replace these components with the same type of component. |
