4.9 Fans
Six dual-rotor 40 mm fans are mounted in a fan assembly that is located in the chassis between the
hard drive bay and the processors. Only five fans are populated in systems with a single processor
configuration. Each fan has a connector that plugs directly into the planar. The R610 fans cannot be
hot-swapped. There are six fan zones in the R610, with one zone for each system fan.
The Embedded Server Management logic in the system controls and monitors the speed of the fans. A
fan failure or over-temperature in the system results in a notification from iDRAC6.
The R610 Power Supply Units do not have any integrated fans; they are cooled by the system fans in
front of them. The system requires a power-supply blank (metal cover) in place of the empty power
supply slot. System fan speed is pulse-width modulated. Redundant cooling is supported.
To provide cooling when the system is off, both rotors in FAN_MOD1 run off V
aux
power at a low speed
setting when the ambient air temperature in the power supply passes a pre-defined threshold. The
iDRAC controls the fan in AutoCool mode.
4.10 LCD Control Panel
The LCD control panel is located on the front of the system chassis to provide user access to buttons,
display, and I/O interfaces. See Figure 6. The control panel includes the following features:

ACPI-compliant power button with an integrated green power LED (controlled by iDRAC6)

128x20 pixel LCD with controls:
o Two navigation buttons
o Select button
o System ID button

Non-maskable Interrupt (NMI) button (recessed)

Ambient temperature sensor
