This section describes the indicators and connectors on the front and rear of the XL-12000S modem.

5.1Front Panel Indicators

Figure 5.1 shows the LED indicators that provide status and opera- tional information on the XL-12000S Modem.

Power LED

The blue Power LED remains lit while the unit has power.

Activity LEDs

The DSL RX and DSL TX LEDs flash green when receiving and transmitting data.

Status LED

At power up, the Status LED flashes red while the modem performs a diagnostic self-test and performs software decompression. After the modem completes its self-test, the LED will extinguish, indicating that the modem is ready for normal operations.

The Status LED will flash red when software is being downloaded during subsequent maintenance activity. Steady red indicates unit failure; refer to the “Troubleshooting” section of this manual.

DSL Link

A flashing DSL link LED indicates that the modem is in the process of linking to the other modem. After the two XL-12000S units have secured the DSL link, the DSL Link LED glows a steady green. The LED is off when there is no link. If the link remains off, refer to the “Troubleshooting” section of this manual (section 10.0).
