CAUTION
The EBA contains two blowers and provides cooling that
is VITAL to prevent service outage and possible damage
to the LPAs. Since the SC 4812ET can continue to operate
normally with one functional blower in the EBA, the EBA
should not be removed until the replacement EBA is
onsite. Then, the EBA is replaced as a unit while the RF
cabinet is running. The replacement must be done within 3
minutes to prevent damage to the LPAs. Refer to the SC
4812ET FRU Guide for details regarding FRU
replacement.
