Field-Replaceable Units in an EX8216 Switch
Field-replaceable units (FRUs) are switch components that you can replace at your site. The EX8216 FRUs are hot-insertable and hot-removable: You can remove and replace them without powering off the switch or disrupting the switching function.
 | Note: We recommend that you take some of these components offline before removing them from the switch. See Table 1 for details. |
Table 1 lists the FRUs for the EX8216 switch and actions to take before removing them.
Table 1: FRUs in an EX8216 Switch
FRU | Action to Take Before Removing the Component |
|---|---|
Power supplies (AC or DC) | None. |
Fan trays | None. |
Routing Engine (RE) module | Redundant configuration:
Base configuration:
|
Switch Fabric (SF) module | To avoid packet loss you must take the SF module offline before removing it. See Taking the SF Module Offline in an EX8216 Switch. |
8-port SFP+ line card 40-port SFP+ line card 48-port SFP line card 48-port RJ-45 line card | We recommend that you take the line card offline before removing it. See Removing a Line Card from an EX8200 Switch. |
SFP and SFP+ transceivers | None. |
| Note: Line cards are not part of the base or redundant configurations. You must order them separately. See EX8216 Switch Configurations. |
| 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. |
