NTP-D107 Inspect and Maintain the Air Filter
Warning
Do not reach into a vacant slot or chassis while you install or remove a module or a fan. Exposed
circuitry could constitute an energy hazard.
Statement 206
Note
Although the filter works if it is installed with either side facing up, Cisco recommends that you install
it with the metal bracing facing up to preserve the surface of the filter.
Note
Avoid cleaning the air filter with harsh cleaning agents or solvents.
Step 1
Verify that you are replacing a reusable air filter. The reusable filter is made of a gray, open-cell,
polyurethane foam that is specially coated to provide fire and fungi resistance. NEBS 3E and later
versions of the ONS 15454 SDH use a reusable air filter.
Step 2
If the air filter is installed in the external filter brackets, slide the filter out of the brackets while being
careful not to dislodge any dust that might have collected on the filter and proceed to
illustrates a reusable fan-tray air filter in an external filter bracket.
Step 3
If the filter is installed beneath the fan tray and not in the external filter brackets, open the front door of
the shelf assembly by completing the following substeps:
a.
Open the front door lock.
Turn the key counterclockwise to unlock the door and clockwise to lock it. (The ONS 15454 SDH
comes with a pinned hex key for locking and unlocking the front door.)
b.
Press the door button to release the latch.
c.
Swing the door open.
Purpose
This procedure explains how to inspect and maintain reusable air filters.
It
ensures that the air filter is free from dirt and dust, which allows
optimum air flow and prevents dirt and dust from entering the shelf.
Tools/Equipment
Vacuum or detergent and water faucet, spare filter, pinned hex key tool
Prerequisite Procedures
None
Required/As Needed
Clean the filter every three to six months. Replace the air filter every two
to three years.
