Field-Replaceable Units in ACX7100-48L Routers

 

Field-replaceable units (FRUs) are components that you can replace at your site. The following are the ACX7100-48L FRUs:

  • Power supply modules (PSMs)

  • Fan modules

  • Transceivers

Caution

Replace a failed PSM with a new PSM within three minutes of removal to maintain power redundancy. The router continues to operate with only one PSM running. Replace a failed fan module with a new fan module within one minute of removal to prevent chassis overheating.

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 does not apply if you replace existing components with the same type of component.

Note

Before removing the optical transceivers, we recommend that you disable the interface using the set interfaces interface-name disable command.
