Dell R610 manual Fans, Control Panel / LCD

Dell™ PowerEdge™ R610 Technical Guidebook

I. Fans

Six dual-rotor 40mm fans are mounted in a fan assembly that is located in the chassis between the hard drive bay and the processors. Only five fans will be populated in systems with a single processor configuration. Each fan has a connector that plugs directly into the planar. (The PowerEdge R610 fans cannot be hot-swapped. There are six fan zones in the R610, with one zone for each system fan.) System fan speed is pulse-width modulated. Redundant cooling is supported with only one rotor failing at a time. The Embedded Server Management logic in the system will control and monitor the speed of the fans. A fan failure or over-temperature in the system will result in a notification from iDRAC6.

The PowerEdge 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 PSU Close Out (metal cover) in place of the empty power supply slot. To provide cooling when the system is off, both rotors in FAN_MOD1 will run off of Vaux power at a low speed setting when the ambient air temperature in the PSU passes a pre-defined threshold. The iDRAC controls the fan in AutoCool mode.

J. Control Panel / LCD

The system control panel is located on the front of the system chassis to provide user access to buttons, display, and I/O interfaces. Features of the system control panel include:

•ACPI-compliant power button with an integrated green power LED (controlled by iDRAC6)

•128x20 pixel LCD panel with controls

•Two navigation buttons

•One select button

•One system ID button

•Non-Maskable Interrupt (NMI) button (recessed)

•Ambient temperature sensor

•Two external USB 2.0 connectors (with an internal USB connector and Internal SD Module)

•15-pin VGA connector

The LCD panel is a graphics display controlled by iDRAC6, unlike the 9G panel which had its own CPLD. Error codes can be sent to the display by either iDRAC6 or BIOS.
