4. MAINTENANCE
The T400 Single Environmental Housing requires no
routine maintenance to function properly.
Electrical shock can occur if surge
arrestor replacement is attempted
before removing the powering
modules.
In cases where lightning is the suspected cause of
circuit pack failure, ADTRAN recommends replacing
all surge arrestors within the environmental housing.
The surge arrestors are field replaceable as detailed in
section 2.
The cover assembly O-ring should be replaced if entry
is gained and the O-ring has been in place for 90 days
or longer.
