Chassis Fan Tray Removal and Replacement Guide 7
Operating Guidelines Follow these operating guidelines for the fan trays for the Switch 4007R
8-slot chassis.
CAUTION: For the module bay area and the power supply bay area, if a
fan in one fan tray fails, a trap message alerts you to replace the fan tray
within 48 hours. For the power supply bay area, if a fan in one fan tray
fails and the temperature is 45 °C (113 °F) or greater, a trap message
alerts you to replace the fan tray immediately. The Switch 4007R sends a
trap message and can continue to run if one fan fails in one fan tray.
However, if a second or third fan fails, in that same fan tray, no trap
message is generated.
