Fan Filters
The Total Access 1248 Expansion DSLAM fan module comes with a single fan filter. The filter
is designed to remove particles from the air before it is pushed through the system.
Replacement filters are available from ADTRAN. This filter should be inspected at least every
90 days and replaced as necessary.
To replace a filter, remove the fan module, remove the old filter material and tuck the new
filter in, ensuring that the edges of the filter are behind the metal tabs provided to hold the
filter (see
).
SNMP/TFTP AND TL1 CONFIGURATION STORAGE AND RETRIEVAL
Use the following SNMP/TFTP and TL1 commands to store or retrieve the Total Access 1248
System Configuration Archive (SCA) file.
NOTE
In some installations, the configuration file can be stored and
retrieved in one operation for multiple Total Access 1248 systems.
This is accomplished by incorporating the SNMP/TFTP or TL1 com-
mands into scripts.
