2.6 Heat Dissipation System
This section describes the principle, fan modules, and fan module control modes of the E9000
chassis heat dissipation system.
2.6.1 Introduction
This section describes the components, heat dissipation performance, and fan module
installation slots of the E9000 heat dissipation system.
Fan Modules and Heat Dissipation Capability
The heat dissipation system of the E9000 chassis consists of 14 fan modules. When the E9000
chassis is fully configured with fan modules, the maximum heat dissipation power
consumption is as follows:
l Compute node slot (35°C or 95°F ambient temperature):
– Half-width slot: 900 W
– Full-width slot: 1800 W
l Compute node slot (40°C or 104°F ambient temperature):
– Half-width slot: 700 W
– Full-width slot: 1400 W
l Switch module slot: 280 W
l Management module slot: 80 W
Figure 2-11 shows the installation positions and slot numbers of fan modules in the chassis.
Fan Module Zones
The 14 fan modules are divided into three zones. Each fan module contains two fan units. If a
fan unit or module fails, heat dissipation is not affected.
Figure 2-17 shows the fan module zones, which are distinguished by colors.
l The pink fan zone dissipates heat for the pink front compute node zones.
l The turquoise fan zone dissipates heat for the turquoise front compute node zones.
l The orange fan zone dissipates heat for the orange rear module (management modules
and switch modules) zones.
