4.9 Fans

Six 120mm single-rotor hot-swappable fans are mounted in a fan bay in the rear of the chassis. Each
fan has a single wire harness that plugs into the planar fan connectors (FAN1 through FAN6).
The Embedded Server Management (ESM) logic in the system controls and monitors the speed of the
fans. A fan speed fault or over-temperature condition results in a notification by ESM.
The R910 Power Supply Units have integrated fans. The system requires a blank in place of the empty
power supply slot. System fan speed is pulse-width modulated.
The iDRAC6 controls and monitors the speed of the fans. A fan speed fault or over-temperature
condition results in a notification by iDRAC6.
