Caution: Do not operate the chassis without the fan tray(s) installed. Doing so even for short periods of time may cause the system to overheat and result in component damage.
ESD Caution: During installation, maintenance, and/or removal, wear grounding wrist straps to avoid ESD damage to the components. Failure to do so could result in damage to electrical components and could potentially void your warranty.
To monitor chassis temperature and fan speed, issue the following command in the CLI’s Execute mode:
• 0: There are no errors. This is the normal operating condition.
• 2: Multiple fans on the fan tray have failed.
• 4: A single fan on the fan tray has failed.
• 8: The redundant fan controller on the fan tray did not respond to the heartbeat signal.
• 10: An error has occurred on the primary fan controller bus for the fan tray.
• 20: An error has occurred on the redundant fan controller bus for the fan tray.
• 40: An inter-bus communication error was experienced between the primary and redundant fan controllers on the fan tray.
• 80: The fan tray is not present.Warning: The upper fan tray assembly contains multiple fans that are spinning at a high rate of speed when the system is powered on. If system is powered on, do not touch moving fans. To minimize the risk of personal injury and potential damage to equipment, follow these instructions.
