Understanding the LEDs on the SCHD
Last Updated: Feb 23, 2018 10:35AM EST

This article applies to:  Echo360 Admins

The front of the Echo360 SafeCapture HD has 10 LEDs, grouped in two banks of 5, as shown in the photograph below. There is also an Echo360 logo light in the center, between the two banks, that indicates recording status of the device.

As indicated in the picture, to identify each of the LED lights, we have numbered them 1 to 10, from left to right. Each light and its indications are described in more detail in the section below.

Each LED can display different colors (blue, green, yellow, orange, red). Some also blink. The colors and blinking indicate different states, as identified in the following graphic.

This information is downloadable as an Excel spreadsheet (LED-MatrixNumbered-052012.xlsx) for screenreader users if necessary.

color-coded device states for the LED lights on the SafeCapture HD

In the above table, some text is demarcated by asterisks (example: *>95%*). The asterisks mean that the LED blinks.

The color of the text matches the LED blink color. For example, the CPU Load light (LED3) blinks white when the CPU load is above 95 percent. This is shown in the table by the white "*>95%*." text.

Descriptions of the LEDs

Each of the LEDs on the front of the SafeCapture HD device is described below. The LEDs are numbered 1 through 10, from left to right as you are looking at the front of the device.

Power (LED1): Indicates the power state of the appliance. Depending on the model of SafeCapture HD, this light can indicate the following:

  • In SafeCapture HD models with serial numbers containing PHB or later, this light is connected to the power supply and indicates that there is power to the device and the power switch is turned on. If the light is off, the device is not receiving power and may have a blown fuse. See Troubleshoot the SafeCapture HD Power Supply for more information on checking and replacing fuses.
  • In SafeCapture HD models with serial numbers PHA and earlier (for example, PGH), the light is active only when the unit starts (boots up).

Mean Temp (LED2): Indicates the mean internal temperature of the appliance, based on measurements from seven on-board sensors.

Action Required if LED2 blinks white!!

The Mean Temp indicator (LED2) blinks rapid-white if any internal sensor detects a component over its rated temperature. Cool the appliance immediately:

  • Ensure that all the exhaust fans and intakes on either side of the appliance have ample clearance.
  • Provide sufficient ventilation to enclosed spaces containing an appliance, such as podia and equipment closets. Heat accumulates in enclosed spaces.
  • Use the provided rack-mounting hardware to mount the appliance in an enclosure designed for professional-grade electronics.
  • Relocate the appliance to an open air environment if the enclosed space cannot provide appropriate ventilation.

CPU Load (LED3): Indicates the total percentage load of the central processing unit (CPU).

DSP Load (LED4): Indicates the combined total percentage load of the channel-1 and channel-2 digital signal processors (DSPs). This light is not active. It will almost always be blue.

Eth0 (LED5): Indicates the interface and link state of the appliance's Ethernet port.

Echo360 logo. The round Echo360 logo between the two LED sets shows capture worker status. Off means the device is idle; Red means the device is recording; blinking indicates the capture binaries (firmware) are restarting.

USB (LED6): Indicates the state, if any, of devices connected to the appliance's USB port.

Echo Com (LED7): Indicates the state of the appliance's communications connectivity with the Echo360 server.

IP Config (LED8): Indicates the state of the appliance's IP configuration.

Channel 1 (LED9): Indicates the status and type of signal(s) present on input channel 1.

Channel 2 (LED10): Indicates the status and type of signal(s) present on input channel 2.

When more than one signal is present on Channel 1 or Channel 2, the indicators will alternate between the colors representing those signals while the device is idle. While the device is recording, only the recorded signal's color is lit.
