LED display
The front panel’s LEDs (see figure 4) display the status of the four WAN ports, the iDSL ports, the Ethernet
LAN port, power, and the alarms. The front panel includes LEDs for:
• POWER: Green if power is being applied. Flashing if one power supply fails.
• CPU FAIL: Red if the CPU fails.
• ALARM: If the DACS is operating normally, the LED will be off. If a major alarm has occurred, the yellow
LED will flash; if a minor alarm condition exists, the LED will be lit constantly.
• SYSTEM: Flashes green if the iDSL Multiplexer is operating normally.
• ETHERNET: Green if Ethernet link status is normal.
• EXT. CLOCK: Green if the iDSL Digital Cross Connect is being driven by the BITS clock. Off if the
Model 3092 is connected to a (T1/E1) Network Clock or Internal Clock.
• TEST MODE: Yellow if any of the 24 DSL ports or any of the T1/E1 ports are in local switching or loop-
back mode, respectively. Off if all ports are in normal operation.
• DSL PORTS: Green to indicate end-user activity on any of the 24 iDSL ports. Red indicates loss of sync on
any DSL port.
