Never install an AC power module and a DC power module in the same chassis.
To install a second DC PEM for redundancy:
Do not power off the DC PEM in a system that has only one PEM. If you do so,
all data traffic halts.
Set the power switch on the new DC PEM to 0 (off).
Loosen the captive screws and remove the blank cover from the empty power bay.
Insert the new PEM all the way into the power bay to ensure a secure connection
to the midplane. Tighten the captive screws.
For instructions on wiring the new PEM, refer to the installation document that
arrived with the PEM, or to the wiring procedure in the Cisco 10005 ESR
Hardware Installation Guide.
Never install an AC power module and a DC power module in the same chassis.
To replace a DC PEM:
Set the power switch to the 0 (off) position. If you have redundant PEMs, set only
the power switch of the PEM you are replacing to the 0 (off) position.
Do not power off both of the DC PEMs in a redundant system, or the system shuts
and down all data traffic stops. Only power off the DC PEM you are replacing.
