The control panel located on the front of TelVue server chassis, including the HyperCaster B2000 AIO, HyperCaster B100 AIO, B1000 HyperCaster, ProVue, InfoVue, and TeleCast 2, has five LEDs. These LEDs provide you with critical information related to different parts of the system. Each LED illuminates to indicate different statuses.
The Alert LED is illuminated when an alert condition occurs. A solid red light indicates an overheat condition in the system. A flashing red light which flashes in one second intervals indicates a fan failure. A flashing red light which flashes in four second intervals indicates a power failure. When notified of an alert, check the routing of the cables and make sure all fans are present and operating normally. You should also check to make sure that the chassis covers and air shrouds are installed. This LED will remain flashing or on as long as the temperature is too high or a fan does not function properly.
For an overheat condition or fan failure, if possible, you should power the unit down immediately and allow it to cool. For an overheat condition, ensure the room in which the unit is housed is at a cool enough temperature for operation. Attempt to clear the space around the unit to ensure it is able to properly cool, ensuring the intake and exhaust areas for the fans are unobstructed by cabling and other hardware and clear of dust and other debris. If after restarting the unit returns to an overheat condition, power down the unit and contact TelVue Support by emailing firstname.lastname@example.org.
The Overheat/Fan Fail LED is used to indicate a fan failure or overheat condition. When this LED blinks red, it indicates a fan failure and when blinking red slowly a power failure.
The Informational LED is used to indicate a fan failure, power failure, overheat condition, or to identify the unit within a large rack installation. When this LED blinks red quickly, it indicates a fan failure and when blinking red slowly a power failure. This LED will be blue when used for UID (Unit Identifier). When on continuously red, it indicates an overheat condition, which may be caused by cables obstructing the airflow in the system or the ambient room temperature being too warm. For an overheat condition or fan failure, your server may also make an audible alarm (beeping). Consult with the chart below to identify the cause of the alarm:
The Network Interface Controller (NIC) LEDs indicate network activity on the corresponding Gigabit Local Area Network (GLAN) when flashing. Depending upon your implementation, you may only have one of these indicators flashing.
The Hard Disk Drive (HDD) LED indicates HDD activity. This LED should be blinking during normal operation.
The Power LED indicates power is being supplied to the system’s power supply units. This LED should normally be illuminated when the system is operating.
