5.0Panel Indicators and Connectors

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

5.1Front Panel Indicators

Fig. 5.1 shows the LED indicators that provide status and operational information on the XL-12000B 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.

Steady red indicates one of two conditions: 1) the link is lost and the modems are trying to establish a link or 2) there is a unit failure.

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-12000B units have secured the DSL link, the DSL Link LED glows a steady green. The LED is off when there is no link.

Master/Slave Switch

One XL-12000B serves as the Master unit and the other serves as Slave. It does not matter which unit of the pair is set to “Master” and which is set to “Slave”, but the pair must have opposite settings. Changing this switch does not require the user to reboot the modems.
