DLP-G737 Replacing 15454-M6-DC With 15454-M6-DC20 Power Module
Note
The procedure to replace the 15454-M6-DC power module with 15454-M6-DC40 power module is the same
as this procedure. The 15454-M6-DC40 power module uses 15454-M6-DCCBL2-L= and
15454-M6-DCCBL2-R= cables.
Note
Do not replace the 15454-M6-DC with the 15454-M6-DC20 power module if the ONS 15454 M6 shelf is
consuming more than 960 W of power. Refer to
the shelf.
Caution
While changing the power modules from 15454-M6-DC20 to 15454-M6-DC and vice-versa, the ONS 15454
M6 shelf can temporarily work with both 15454-M6-DC and 15454-M6-DC20 power modules installed.
However, during regular operation, the shelf must either have the 15454-M6-DC or 15454-M6-DC20 power
module, but not both.
Caution
Always use the supplied ESD wristband when working with a powered ONS 15454 M6. For detailed instructions
on how to wear the ESD wristband, see the
Cisco ONS Platforms
Procedure
Step 1
Disconnect the power source opening the breaker on top of the standby power module (installed in slot B).
Step 2
Unscrew the holding screw that secures the 15454-M6-DC power module.
Step 3
Pull the 15454-M6-DC power module clear from the ONS 15454 M6 chassis.
Step 4
Remove the power connections from the standby power module.
Step 5
Install power on the 15454-M6-DC power module as described in the
to the ONS 15454 M6 Shelf , on page
Note
Step 6
Install the 15454-M6-DC power module as described in the
ONS 15454 M6 Shelf, on page
Step 7
Connect the power source closing the breaker on top of the standby power module (installed in slot B).
Step 8
Perform the Step 1 to Step 7 for the active power module (installed in slot A) procedure.

While replacing the power modules, do not provision or install any line cards when the ONS 15454
M6 chassis is in the mixed power mode. Card provisioning and installation must be done only after
both the slots have the same type of power modules.

To ensure that the controller card is calculating the shelf power consumption correctly, reset the
controller card. For details about performing card reset, see the "NTP-G106 Reset Cards Using
CTC" procedure in the Cisco ONS 15454 DWDM Configuration Guide.If the power consumption
of the shelf is exceeding 960 W, the PWR-CON-LMT alarm is raised. Either revert to the
15454-M6-DC power module or remove and deprovsion the existing line cards to reduce the load.
