Filler and Blank Cards
Filler cards must be installed in unused and empty slots to ensure proper air flow and electromagnetic
interference (EMI) requirements during the ONS 15454 M6 operation. CTC detects filler cards from R 10.6
onwards.
There are two types of card fillers:
• Line card fillers (15454-M-FILLER)
These filler cards operate in slots 2, 3, 4, 5, 6, and 7, and have no card-level LED indicators.
The following figure shows the faceplate of line card filler.

• Timing and Control Card fillers (15454-M-T-FILLER)
These filler cards are for control cards that operate in slots 1 and 8. The following figure shows the faceplate
of timing and control card filler.

Blank cards (15454-BLANK) can be installed in any empty slot in the shelf. CTC does not detect blank cards.

Air Filter
The ONS 15454 M6 contains a preinstalled reusable air filter (15454 M6-FTF) on the right side of the shelf.
The reusable filter is made up of a gray, open-cell, polyurethane foam that is specially coated to provide fire
and fungi resistance. Spare filters should be kept in stock. Inspect the air filter every 30 days, and clean the
filter every 3 to 6 months. The air filter can be replaced without removing the fan-tray assembly. However,
the fan-tray must be turned off to remove the air filter. Replace the air filter every two to three years. Avoid
cleaning the air filter with harsh cleaning agents or solvents.
Do not operate an ONS 15454 M6 without the mandatory air filter.
