• LED is off when the battery is not connected
• LED turns green when the battery is connected and the power module functions correctly
• LED turns red when the battery is connected but there is a failure due to a secondary fuse break (48 V
DC) or AC module fan failure.
When the ONS 15454 M6 shelf is powered at –60 VDC (nominal), only the TNC, OPT-AMP-C,
OPT-AMP-17-C, OPT-EDFA-17, and OPT-EDFA-24, 17 SMR9 FS, 24 SMR9 FS, 34 SMR9 FS, SMR20
FS, SMR20 FS CV, 12-AD-FS, 16-AD-FS, 100GS-CK-LC, and MR-MXP cards, and the 15454-M6-ECU-60
can be installed. Note
The 15454-M6-DC40 power module is required to accommodate up to four 100GS-CK-LC cards in a
ONS-15454-M6 shelf.
For the 15454-M6-DC20 power module, the power consumption of the ONS-15454-M6 shelf (including
ancillaries, controller cards, and line cards) is limited to 960 W. A new line card will not boot up when it is
installed in the ONS-15454-M6 shelf, if it causes the power consumption of the shelf to exceed 960 W. The
PWR-CON-LMT alarm is raised in the Alarms tab in CTC when the installation or pre-provisioning of a card
causes the power consumption to exceed the limit of 960 W.
For the 15454-M6-DC40 power module, the power consumption of the ONS-15454-M6 shelf (including
ancillaries, controller cards, and line cards) is limited to 1920 W. A new line card will not boot up when it is
installed in the ONS-15454-M6 shelf, if it causes the power consumption of the shelf to exceed 1920 W. The
PWR-CON-LMT alarm is raised in the Alarms tab in CTC when the installation or pre-provisioning of a card
causes the power consumption to exceed the limit of 1920 W.
The total power consumption of the shelf is calculated by the controller card and displayed in CTC in the
Provisioning > Power Monitor tab. For details about power calculation, see
Power Calculation, on page 478 .
Note
The terminal lugs used on the DC power modules are included in the accessory kit (53-3318-01) and part
number of the terminal lug is 32-0603-01 (4 pieces). The accessory kit is placed under the 15454-M-SHIPKIT=
PID.
Changing the DC Power Module
It is possible to change the power modules without powering down the ONS 15454 M6 system. While changing
the power modules, ensure that only one power module is replaced at a time and the other power module
continues to supply power to the shelf. However, during regular operation of the node, the ONS 15454 M6
shelf must have 15454-M6-DC20 or 15454-M6-DC or 15454-M6-DC40 power module. See
DLP-G737
Replacing 15454-M6-DC With 15454-M6-DC20 Power Module, on page 363 and DLP-G738 Replacing
15454-M6-DC20 With 15454-M6-DC Power Module, on page 365 for changing the power modules.
Power Filler Module
For redundant power supplies, two AC or DC power modules can be installed in Slot A and Slot B of the
ONS 15454 M6 shelf. However, only one power module can sustain the functioning of the entire ONS 15454
M6 system. In that case, insert a power filler module in the empty slot.
