Cages
Please consult Figure 36 above to determine where each fan cage is in the
chassis. Fans 1 through 8 are in Fan Bank 1, and fans 9 through 12 are in
Fan Bank 2.
chassis. Fans 1 through 8 are in Fan Bank 1, and fans 9 through 12 are in
Fan Bank 2.
Once you have extracted the fan cage, find the failed fan. There is a good
chance that hair or dust has collected on the fan and all it needs is to be
cleaned. Blowing compressed air into the axle of the fan can clear
obstruction or debris. If the fan cannot be cleaned or repaired, the entire
cage must be replaced.

5.5 Batteries
The system has two batteries; both are located directly in front of Fan
bank 2. These batteries are redundant and will power the entire system -
in the event of an external power failure – long enough to copy all of the
data in the RAM cache to the Flash storage. Internal sensors report on
the battery voltage level and a monthly test ensures that the current
supplied from batteries will be able to power the system. If the battery
voltage is out of specification or the monthly battery test fails, warnings
are reported. If they degrade and are unusable, errors are reported. The
batteries are redundant so the cache is not at risk in the event of a power
failure, however, replacing the failed battery quickly is recommended.
The batters in the RamSan-500 will last on average for 2-3 years.
