Replacing the IDU (PSE/W or PSE/L)
In case the replacement of the IDU is required, the following procedure has to be followed.

Take from the stock a spare unit with the same P/N of the unit to replace
2)
In case the IDU (PSE) is part of a Protection Group (1+1 HSB system) the following actions
are required.
First put the system in a Forced status:
i. To replace the IDU of the Main, set in ODU Main
System
Settings→Protection

Settings→Protection
window (par. 2.10)) the field
Forced Mode
to
Forced
and verify
that the ODU Main status in the
System Status

If the User traffic is only connected to the USER port of the IDU to be replaced, a manual
reconfiguration has to done, moving the User cable to the USER port of the other PSE in
order to guarantee service continuity and configuring properly the USER interface of this
PSE.
If the User traffic is connected to both USER ports of the two PSE, USER ETH interface
configuration of the PSE remaining in service has to be modified in order to guarantee that
User traffic is only routed through this interface.
3)
Wear the antistatic armlet and connect its termination to a grounded structure.
4)
Turn off (position O) the power switch on the front of the IDU unit to replace.
5)
Disconnect all the cables from the front panel, taking care of putting marking labels (if not

the Interconnection cable between the two PSE has to be disconnected.
6)
Extract the IDU box from the shelf unscrewing the two screws.
7)
Insert the new IDU unit in the support frame.
8)
Reconnect all the cables on the IDU front in the original position.

Panel are blinking.
