Option Card Slot
The option card slot is a standard feature. An optional network adapter card slides into the slot which is located on the back of the electronics module (figure 1, page 9). This optional interface allows the UPS to be monitored across the network or from any point on the Internet (refer to the Communication Option User Manual for a more detailed explanation of this option).
Troubleshooting
Warnings and Faults are those abnormal conditions that can occur and could cause the unit to stop normal operation. These conditions are detected by the protective circuitry in the unit. The UPS “Warning/Fault” lamp will lightred when a warning or fault occurs. "Troubleshooting" involves monitoring the LED’s on the front panel and then interpreting the readout by using the warning and fault mode display charts that follow. Only the state of the LED’s listed in the chart should be considered. Other LED’s might be active; nevertheless, only those listed under the column “LED state” should be considered when diagnosing a warning, or fault.
Warning/Fault Modes
All warnings will cause the red “Warning/Fault” LED to flash. All faults will cause the red “Warning/Fault” LED to light continuously. Some warnings and most faults will cause the UPS to transfer to bypass mode. In many cases, after the condition that caused the fault is corrected the unit will automatically transfer back to normal mode. For those cases where the unit does not transfer back automatically contact your Toshiba UPS service representative at 1-
