As SN# FDO1712R1LE provided for service RMA# 87368210 was added to the contract# 95860673 on 26-JUL-2016, which gives Cisco less than 30-day notice at the time of service RMA creation, the service RMA ship date will be revised to 30th days to allow time to bring in the required inventory into the country to support this RMA. The new ship date is 25-AUG-2016 If you have any questions, please let us know.
