FAQ C120 and C130 Lightbar Operation
Overview
The Gateways offer a Lightbar that can be used to assist in placing the external antenna in the optimum location to enhance the signal strength. The Lightbar provides a visual indication of the RSSI Signal Strength and is available on the C120, C130, C131, C132 and C134.
The lights shown when the Gateway is in operation are a snapshot of the last signal check. Signal strength is automatically checked at boot and before every new call is placed.
 |
Lights | Signal Strength |
| One LED | Poor | |
| Two LEDs | Fair | |
| Three LEDs | Good | |
| Four LEDs | Excellent | |
| Top and Bottom LEDs flashing | No Signal | |
| Any LEDs strobing (on solid, flash, on solid, flash in a continuing sequence) | No PPP Connection. This is displayed when the connection to the cell tower is available but the connection through the cell network to the destination server is not established. | |
| Four LEDs flashing rapidly | Low cell modem memory detected |
| Note: | The Lightbar reflects the measurement from the last sample taken at boot or prior to the placement of a call. |
| Note: | Verizon can put a “hold off” (refuse connection for four hours) on the card if three connection attempts are made and each tried with in two minutes from each other. When this occurs the LightBar LEDs will flash 1 and 3 at the same time then 2 and 4 at the same time. Retry is every four hours or you can eject and reinsert card. |
Activation Status Indicators
If an unprovisioned Air Card is installed in the unit, the Air Card's LEDs can indicate the status of the activation.
| Operation | Meaning | |
| Toggle (1-2, 2-4, repeat) |
Card is currently not activated, and cannot be activated doe to an activation failure, or invalid information in the provisioning config file. If the card is a Verizon card/module, it will retry every 10 minutes to re-activate. |
 |
| Light moving upward (1, 2, 3, 4, repeat) |
Card is currently activating. |
 |
| Light moving downward (4, 3, 2, 1, repeat) |
GatherStats is runing. Do not interrupt this operation.. |
 |
| Note: | The activation indicators are currently available (2/1/2008) only with Novatel series cards. |
Signal Strength Commands
During normal operation, two commands are available through the Console/Telnet Command Line Interface or the web browser interface.
| Command | Function |
| checksignal | Updates the Lightbar in real-time. Warning: this command will terminate any active Wireless PPP connection. |
| getsignal | Displays a log of the last 10 to 15 signal checks. |
These commands are available through the Console/Telnet Command Line Interface and the JBM GAU GUI interface.
