Installing a Second DC PEM
Warning
Never install an AC power module and a DC power module in the same chassis.
To install a second DC PEM for redundancy:
Caution
Do not power off the DC PEM in a system that has only one PEM. If you do so,
all data traffic halts.
Step 1
Set the power switch on the new DC PEM to 0 (off).
Step 2
Loosen the captive screws and remove the blank cover from the empty power bay.
Step 3
Insert the new PEM all the way into the power bay to ensure a secure connection
to the midplane. Tighten the captive screws.
Step 4
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

Replacing a DC PEM
Warning
Never install an AC power module and a DC power module in the same chassis.
To replace a DC PEM:
Step 1
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.
Caution
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.
