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.
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
