FIGURE 9-10 Removing the PSU (Front of the M9000 Base Cabinet)
7. Place the removed PSU on an antistatic mat.
8. Mount the replacement PSU by following the removal instructions in Step 5 and
Step 6 in reverse order. Align the PSU with the slot guides, insert it carefully, and
secure it firmly.
Caution – Each cabinet contains multiple PSUs so that the power output specifications are
satisfied even if one PSU fails. However, please refrain from the long time operation as one
PSU remains failed.
Caution – Do not forcibly push the PSU when inserting it, even if it is not moving
smoothly. You may fail to insert the PSU due to the presence of any obstruction in a slot or
any problem with a connector pin; and if you forcibly insert it, serious damage may result.
