What are the steps to take if the serial number is missing in the show rsp chassis-info command?
A. This output shows that the serial number is missing: #show rsp chassis-info Backplane NVRAM(ver 255) contents: Chassis model: 0xFF Chassis S/N: 0 MAC block size: 416 RMA failure: 255 RMA number: 16777215 Manufactured Date: 255 255 255 In case the serial number information is missing, this can be resolved using a EPROM programming command using the actual S/N obtained from the exterior of the device. This is the procedure for EEPROM programming of the serial number: • In order to program the serial number on the EEPROM, you need to write the address 2,3,4,5. For example, if the serial number is 63918102, then in hexadecimal, it is 0x03CF5016. Therefore, address 2 equals to 03, address 3 equals CF, address 4 equals to 50, address 5 equals to 16. • In order to program the EEPROM, configure these commands: 7513-RR2#test rsp ds1201 write 2 03 7513-RR2#test rsp ds1201 write 3 CF 7513-RR2#test rsp ds1201 write 4 50 7513-RR2#test rsp ds1201 write 5 16 • Reload the router and then check the
