Updating ONUs
Introduction to ONU update
Updating ONUs means updating ONU software versions remotely through OLTs.
Updating ONU devices requires a large amount of work because, in an EPON system, there are
different types of ONU devices, which use different update files. To improve the ONU update efficiency
and reduce resources consumed by issuing commands to each ONU, the S7900E switches support
batch updating of ONUs by type and OLT port, besides updating of a single ONU. Updating ONUs by
type is recommended because it is efficient and easy-to-use. For the descriptions on the three ONU
update methods, refer to
Table 3-3 .
