The front panel of the Legacy GRIDSMART Processor is used to relay a small but useful set of operational information. It will cycle between various states to facilitate the display of this information.
When operating normally, the front panel rests showing the current cabinet type setting, calls, and phases. Examples for both TS1 and TS2 are shown below. In both cases, cabinet type is indicated in the upper left hand corner and the number of seconds elapsed since system startup is shown in the upper right hand corner.
For TS1, as shown below, the first line indicates observed green phases; * indicates a phase is green and - indicates the phase is not green. In this case, no phases are green. The second line indicates calls being made; * indicates an active call and - indicates no call. Both phases and calls are ordered from left-to-right, 1–16.
For TS2, as seen below, the phases line is preceded with PH and the calls line is preceded with a BIU indicator. The  below therefore indicates BIU 1. Phases for TS2 are indicated by the letters r, y, or g for red, yellow (amber), or green, respectively. A capitalized letter, such as the G for phases 1 and 5 in this example, indicates that the phase just changed to the indicated state. A lowercase letter indicates the phase has been in the indicated state for more than 1 second.
Approximately every 45 seconds, the front panel will display information about the current camera status and the firmware version, as shown below for a system with firmware version 4.3.0 as indicated by the v4.3.0 in the lower left.
If the Processor is on a network using the Network or Switch port, the firmware version will be replaced with IP address on every other display of the camera status.
If your Processor is licensed for add-on Modules such as the Counts Module or the Pedestrian Module it will be indicated below the Cameras Okay line with a single character for each module. For example, C,P would indicate a Processor licensed for Counts and Pedestrians, and Realtime Data. Or C alone would indicate that just Counts is licensed.
The following images show the expected front panel sequence just after powering-on the Processor.
Below is the very first display shown on power-up
The following display indicates the current configured cabinet type. In this case it is TS1, which is the default factory configuration. The second line, Build– Feb 01 2013, is diagnostic information for factory use.
The next display, shown below, indicates that the system is set to recall during the boot process and again that the current configured cabinet type is TS1.
Next the display will indicate system voltages, which is for factory use or diagnosis of a critical failure.
The final display in the power-on process, as shown below, indicates that all hardware has powered up successfully and that the system is now waiting for the firmware to finish booting and take control. In this state, the counter in the upper right corner will be counting backwards, indicating that if the firmware does not boot successfully by the time the counter reaches 0, the Processor will be power cycled in attempts to recover.
Once the system firmware is up and running, you should expect to see the standard operating displays, as described at the beginning, and the rebooting camera status message. At boot time, the camera ports are power cycled so you should expect to see the following display.
After the camera reboot message, it may still be a few minutes before the camera or cameras are fully operational. During that time, you will see the following No Cameras message.
After no more than 7 minutes, properly connected cameras will be fully operational and you should see the previously noted Cameras Okay display.
If you are configuring a system for the first time and have not yet published, the camera status message will be a bit different. As shown below, it will indicate that you have a 1 (or more) new cameras that have not yet been configured.
Camera connectivity and replacement
A camera or connectivity problem will be indicated in a periodic camera status message. In the display below, for example, the camera status is reporting that the only configured camera is currently offline.
In the event you are replacing a camera, you will see a display like the following once you have disconnected the configured camera and connected its replacement. This camera status message indicates that there is one missing camera and one new camera. The missing camera represents the currently configured one you have disconnected and the new camera represents its replacement that you must configure and then publish.
