Replacing or Adding a Power-Supply Module 3-37
Servicing and Upgrading a DPE
If one power supply is off and the other is on, do not turn one on and
immediately turn off the other. Instead, turn one on and wait five seconds
before turning the other off.
If you are adding a new power supply, remove the power-supply
filler module as shown next. If you are replacing a faulty power
supply, remove the power-supply module itself as follows.
