Unit SubStates


Working state changed for:• Configuration• Testing• Clear up error conditions

Faulty units in WO-EX should be replaced as soon as possible

Changing Working State


Switchover possible if unitsin 2N or N+1 redundancyIf unit has ongoing tasks, FCD parameter must beusedIn N+1 units, working statechange from SP to WO doesnot cause switchover

Activating Switchover


Diagnosing faulty units• Change unit state to TETaking out of use• Change unit state to SE-

NH• Transition procedure must

be followed• If tasks ongoing, FCD must

be used• Unit can be removed when

power is off

COMMAND EXECUTED

Restarting


Bring the plug-in units in their inner packages close to the cabinets and place them on an ESD-protected surface.

Connect your ESD wrist strap to the earth bonding point in the cabinet you are working on.

ESD Precautions


Check that the unit working state is SE-NH (USI)

• ZUSI:<unit type>;Change the working state if

the unit working state is not SE-NH, (USC)

• ZUSC:<unit type>,<unit index>:<working state>;

Ensuring Correct Unit State


Remove any cable(s) from thefront panel of the plug-in unit

Unscrew locking screws on thefront panel (A)

Open two insertion/extractionlevers on the front panel (B)

Remove the plug-in unit fromthe subrack (C)

Removing the Unit


Insert the spare plug-in unit in its location (A)

Close the insertion/extraction levers on the front panel of the plug-in unit (B)

Close the locking screws carefully (C)

Insert cable(s) back to the front panel of the plug-in unit if there were any

Installing PIU


Set the functional units of a plug-in unit to the SE-OU working state (USC)

- ZUSC:<unit type>,<unit index>:SE;Set the functional units of a plug-in unit to the TE working

state (USC)• ZUSC:<unit type>,<unit index>:TE;• Check that the repair operation was successful by

starting the total diagnosis of the unit (UDU)• ZUDU:<unit identification>;

Testing the Unit


Set the unit to the SP or WO working state (USC)• ZUSC:<unit identification>:<working state>;

Check that the alarm disappears, if necessary (AAP)• ZAAP;
