Statement 206
Warning
The air filters are single-use only. They must not be cleaned and reused. This is a Telcordia NEBS requirement,
GR-63-CORE Issue 4.
Note
Air filters must be inspected every month. If they are dirty or clogged with dust, they must be replaced with
a new air filter.
Note
If you install the air filter below 15454E-CC-FTA or 15454-CC-FTA, only filters with part numbers
700-23193-01 and 700-23194-01 can be used in this configuration.
Note
Although the air filter can work with older fan trays if it is installed with either side facing up, it is recommended
that you install it with the metal bracing facing up to preserve the surface of the filter. You must install the
air filter with the metal bracing facing up with 15454E-CC-FTA or 15454-CC-FTA.
Caution
To install the air filter inside the air ramp unit (15454E-AIR-RAMP or 15454-AIR-RAMP), use the ETSI
version of the air filter (15454-FTF2 or 15454E-FTF4).
Note
Procedure
Step 1
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 Step 8.
