Service
In the 7015 R30, R40, and R50 CPU Enclosures the I/O card contains the NVRAM while the
NVRAM battery and the TOD (Time-Of-Day) are located in the Operator Panel. You can
drain NVRAM in the following ways:
removing the I/O card
disconnecting the operator panel
removing the CPU module.
When NVRAM is drained it results in a reset of the TOD to 1969 which affects applications.
Draining NVRAM also causes a loss of configuration data.
