Air Filter
The ONS 15454 M2 contains a preinstalled reusable air filter (15454 M2-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 three to six 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 M2 without the mandatory air filter.

pane in CTC. The voltage supplied to the shelf (in millivolts)
is displayed in the Voltage area of the Voltage/Temperature pane. The temperature of the shelf (in degree
Celsius) is displayed in the Temperature area of the pane.
The Voltage/Temperature pane retrieves the following values for the ONS 15454 M2 chassis:
• Voltage A—Voltage of the shelf that corresponds to power supply A, in millivolts.
• Voltage B—Voltage of the shelf that corresponds to power supply B, in millivolts.
• Chassis Temperature—Temperature of the shelf, in degrees Celsius.
In multishelf configuration, the voltage and temperature of each shelf is displayed in the Shelf view >
Provisioning > General > Voltage/Temperature pane.
