2.15.3 Number of PSUs required
As one AC source cable is used for one PSU, the number of PSUs used would be the same as the number
of AC power cables used. The number of PSUs required differs depending on the model and the AC voltage
conditions. For the configuration of the PSU, see ‘
2.15.4 Dual power feed configuration
For details on the dual power feed configuration, see
PRIMEQUEST 2000 Series Installation Manual
(CA92344-0536).

2.15.6 Mounting conditions when using 100V power supply
For details on the mounting conditions when using 100 V power supply, see ‘Appendix G Component
Mounting Conditions’ of the “
PRIMEQUEST 2000 Series Administration Manual
” (CA92344-0539).
2.16 Fan (Cooling mechanism)
The PRIMEQUEST 2000 series uses FANU and fan built in the PSU for cooling the main system. Cooling
area is divided to two groups in a system. The rotation number of fan which cools the part with higher
temperature is increased prior to other fans, which realize efficient cooling of the system.
Note
If all partitions are powered off, fans of PSU_P remain rotating.
In PRIMEQUEST 2000 series, the system is cooled by a total of six PSU built-in fans and FANUs.
For details on the mounting locations of the fans in the PCI_Box, see ‘
