. Attach the other end of RCU link cable to the backup CPU.
6. Switch ON the Power to the backup CPU.
Exchanging Defect BC820 TK857V0003 Cable
To exchange a TK857V0003 cable in a redundant CPU configuration, perform the
following steps:
1. Switch OFF or disconnect Power for the backup CPU.
2. Switch OFF or disconnect Power for the BC820, if external power is
connected.
3. Disconnect the cable from the backup CPU.
4. Disconnect the cable from the BC820.
5. Attach the new cable to the backup CPU
6. Attach the other end of the cable to the BC820.
7. Switch ON or reconnect the Power to the backup CPU and the BC820.
Any disconnection of BC820 cables, that is, TK857V0003, the gigabit cross-over
cable and the optical 50/125µm OM3 fiber is only allowed to take place at the
backup end of a running controller.
Exchange of faulty TK857V0003 is allowed only when both the CPU and the
BC820 are OFF.

Corrective Maintenance Procedures
Changing Fuses – ModuleBus and CEX-Bus
To change the TP830 internal ModuleBus and CEX-Bus fuses:
1. Using a blade screwdriver, release the two spring-loaded captive screws on the
PM8xx cover.
2. Carefully remove the processor unit.
3. Identify both the ModuleBus and CEX-Bus fuse-holders to the right on the
TP830 Baseplate.
4. Using a blade screwdriver, carefully unscrew the fuse-holder containing the
defective fuse. Remove the fuse.
5. Insert a new fuse and replace the fuse holder.
6. Replace the processor unit and tighten the cover screws.
7. Check that the relevant LED lights up.
This topic does not apply to PM891, which does not contain internal fuses.
