HP BladeSystem c3000 User Manual

Appendix. Fan, power supply, and device bay population
guidelines
Figure A-1. Fan population guidelines for HP BladeSystem c3000 Enclosure. For correct operation, fans and
server blades must be installed in the correct fan bays. The Onboard Administrator will ensure that fans and
server/storage blades are correctly placed before allowing systems to power on.
BladeSystem c3000 enclosures ship with four fans installed, supporting up to four half-height devices
or two full-height server blades. Adding two more fans to the enclosure allows population with eight
half-height or four full-height devices:
• Four-fan configuration requires population of fan bays 2, 4, 5, and 6.
• Six-fan configuration enables population of all fan bays.
In a four-fan configuration, the Onboard Administrator prevents blade devices in device bays 3, 4, 7,
and 8 from powering on and identifies the fan subsystem as degraded. To incorporate blade devices
in these device bays, install six Active Cool fans.
