Remarks
Update multiple ONUs by type
In FTTH view, update all the
ONUs of the specified type
attached to the switch (you can
update different types of ONUs
by specifying multiple update
files).
Update one ONU
In ONU port view, use the ONU
update command for an ONU
port.
Update multiple ONUs by OLT
port
In OLT port view, use the ONU
update command for the
created ONU ports under the
specified OLT port.
If an ONU is online and
matches the specified
update file, the ONU is
updated directly.
If the ONU is online but does
not match the update file,
the update will fail.
If the ONU is not online
(because the ONU port is
not bound with any ONU or
the extended OAM
connection fails on the
bound ONU), the OLT waits
and automatically starts to
update the ONU when the
ONU goes online and
matches the specified
update file. If the update file
is wrong, the update will fail.
Before the update, make sure you upload the ONU update files to the S7900E master SRPU (you
cannot use the update files on the slave SRPU to complete the software loading). For detailed
upload procedure, refer to the sections discussing software maintenance in
3Com S7900E Family
Getting Started Guide
.
If the ONU which needs to go online can be updated automatically, you need to upload the update
files to the master SRPU and slave SRPU. Thus, update files will be available on the original slave
SRPU after the switchover; otherwise, the update will fail.
Update files used vary with ONUs. If ONUs and update files do not match, the update will fail. For
example, if you specify to update ET704-A ONUs in OLT port view, updating other types of ONUs
attached to the OLT port will fail.
After the update command is issued, the OLT will wait 15 to 20 seconds before executing the
command. This allows for batch updating and saves system resources.
Any power failure during the ONU software upgrade may cause update failure.
Once the update file is transferred to the ONU, the ONU restarts automatically to complete the
update.
The ONU update commands mentioned in this chapter are all configuration commands, that is,
after such a command is executed, it will be saved in the configuration file of the device. If the ONU
port corresponding to an ONU that goes online is created before the update command is used, the
ONU will be updated directly (if it matches the update files). Otherwise, the ONU will not be
updated. To update only the current ONUs online but not the offline ONUs or subsequently
registered ONUs, execute the corresponding update command, and then use the undo form of the
command after you make sure that all online ONUs have been updated.
If an ONU is registered successfully and its corresponding port is UP, it can execute the update
operation as soon as you configure ONU update.
If an ONU is offline or its corresponding port is DOWN, it executes the update operation you
configured after the ONU is registered successfully and its corresponding port is brought up.
