Refer to the exhibit.
You observed some high temperature alerts on a switch shown in the middle rack of the exhibit. The cooling in the data center is following best practices for the layout in the exhibit. The switch is an HPE 5945 series switch, and all the fans are operating normally. The switch is racked so that its ports face the rear of the rack. The administrator noticed the fan modules have red handles.
What should the administrator do to resolve the issue?
The issue arises from a mismatch in the airflow direction of the fan modules relative to the desired cooling path in the data center. The switch is configured with fan modules that have a port-to-power airflow direction, as indicated by the red handles. However, the ports are facing the rear of the rack, which is consistent with a power-to-port direction for optimal cooling. Therefore, replacing the fan modules with power-to-port fan modules will align the airflow with the intended cooling direction, resolving the high temperature alerts.
C. The switches are operating normally. The handles are red (port to power) should be power to port (blue handle)
sure ?
Should be C Document https://www.arubanetworks.com/techdocs/Switches/FlexFabric/5944/5200-7946.pdf Says: Specifying the preferred airflow direction About this task Two fan tray models are available for the device. One model has air flow from the port side to the power supply side. The other model has air flow from the power supply side to the port side. A fan tray can operate effectively only when it uses the same air flow direction as the ventilation system in the equipment room. The preferred airflow direction must also be the same. If a fan tray is not operating correctly or its airflow direction is different from the preferred airflow direction, the system sends traps and logs. You must replace the fan tray. Procedure 1. Enter system view. system-view 2. Specify the preferred airflow direction. fan prefer-direction slot slot-number { port-to-power | power-to-port } By default, the preferred airflow direction is from the port side to the power supply side.
C since ports are on the back side of rack.
