

The SMU breaks down or cannot be started. Its LCD has abnormal display or buttons
cannot be operated.



With alarm reporting enabled, the SMU does not report alarms when the power system is
faulty.



The SMU reports an alarm when the power system is not faulty.



The SMU fails to communicate with the connected lower-level devices even though the
communications cables are correctly connected.



Communication between the SMU and all rectifiers fails even though the rectifiers and
the communications cables are normal.



The SMU cannot monitor AC or DC power distribution when communications cables are
intact and AC and DC power distribution is normal.



Parameters cannot be set or running information cannot be viewed on the SMU.

4.4 Replacing Components

4.4.1 Replacing a Rectifier

Prerequisites



You have obtained an ESD wrist strap, a pair of protective gloves, an ESD box or bag,
and the cabinet door key.



The new rectifier is intact.

Protect yourself from being burnt when removing the rectifier as it has a high temperature.

Procedure

Step 1

Put on protective gloves.

Step 2

Unscrew the rectifier panel using a screwdriver.

Step 3

Gently pull the handle outwards, and then remove the rectifier from the subrack, as shown in

Figure 4-1
