Replacing The Redundant Power Supply Module - Siemens SIMATIC IPC1047 Operating Instructions Manual

7.5.3

Replacing the redundant power supply module

If a fault or an error has been reported for the redundant power supply, the LED of the
defective module lights up (see section "Power indicators, redundant power supply
(Page 18)"). The device also works with the second, non-defective module.
Note
However, to ensure the availability of your system through the redundant power supply,
replace the defective power supply module with a functioning new module as soon as
possible.
• You can continue to operate the device until you can shut it down properly.
• The replacement of one of the two modules of the redundant power supply can be
performed, however, without shutting down the device.
Requirement
● The power supply lines are connected, see section
"Connecting a redundant power supply (Page 38)"
Procedure
Read the section "ESD guideline (Page 103)".
