我从维修手册看到这一段，关于nvm 616-014的：
REP 1.11 SBC SD Card
Parts List on PL 35.2
Preparation
1.If possible, go to dC361 and save NVM.
2.If possible, go to GP 13 and Clone Network Configurations.
3.If possible, print a configuration page.
4.If possible, record the Billing Meter contents. Replacing the SBC SD Card will clear the Billing meters. You will need to report this (GP 20).
Removal
CAUTION
Serial number data is stored at three locations:
• MDM NVM PWB
• SBC SD Card
• IIT/IPS PWB.
If these boards are replaced one-at-a-time, the machine will automatically synchronize the data on the new PWB to match the other two. You must install the new PWB, switch on the power, wait for the numbers to synchronize, then switch off the power before replacing any other PWB.:
If the removal/replacement procedure is not followed correctly, or if data corruption causes one of the following faults:
•16-801.19
•22-352
then you must perform dC132 to restore serial numbers/billing data.
NOTE:
When turning the power OFF, turn OFF the Power Switch first and then the Main Power Switch.
1.Press the Job Status button to check that there are no jobs in progress.
2.Switch off the power and disconnect the power cord.
3.Remove the Control Unit. (REP 1.10)
4.Remove the SD Card (Figure 1) by pushing in the card and releasing it to release the latch, then pulling it out after it ejects.
