Appendix B. Fan, power supply, and device bay population guidelines

Figure B-1. HP BladeSystem c3000 Enclosure – Fan population guidelines. 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.

Base BladeSystem c3000 Enclosures ship with four fans installed, supporting up to four half-height devices or two full-height server blades. Adding two additional fans to the enclosure allows population with eight half-height devices or four full-height server blades.

•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 populate blade devices in these device bays, populate c3000 Enclosures with six Active Cool fans.
