NVRAM is a field replaceable unit (FRU) in the DR Series system (Note: NVRAM is not part of the DR4300e Core system). The super capacitor that powers the NVRAM double-data rate (DDR) memory must be able to move its contents to the solid-state drive (SSD) during a power loss.
If any of these conditions occur, the NVRAM requires either a failure recovery or a replacement.
CAUTION: You must wait a minimum of 20 minutes after powering on the DR Series system before using the DR Series system CLI maintenance --hardware --reinit_nvram command. This 20–minute post power-on waiting period allows the NVRAM card, the super capacitor calibration, and all solid state drive (SSD) processes to fully complete, which are necessary for the proper operation of the DR Series system. |
