4.3 Parts Replacement

4.3.1 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.

Removing a rectifier

Step 4

Insert a new rectifier into the subrack. Then loosen the screws on the handle and pull out the
handle.

Step 5

Push the rectifier into the subrack slowly along the guide rail. Then lock the handle.

Step 6

Tighten the screws on the handle, as shown in Figure 4-2.
