Warning:
• Always keep your fingers away from rotating blades.
• Verify that the fan blades have stopped rotating before removing an impeller tray.
Notes:
• Three impeller trays are recommended for normal operation.
• The trays are hot-swappable. The 7750 SR-12 chassis operates safely while you replace the
fan tray for up to approximately five minutes at an ambient temperature of 95° F (35° C). If a
longer maintenance time is required, power off the system to prevent overtemperature
conditions.
• Immediately replace a tray as soon as an impeller failure is detected.
• In the event of a single impeller failure, the entire tray must be replaced.
• To remove and replace the trays you must have access to the rear of the chassis. You must
have enough room, at least 20-inches, to pull the trays completely out of the slot.
