Power-Up LED SequencHBefore you connect power to the CE150, read this section soyou will understand the LED start-up sequence.3RZHU8S/('6HTXHQFHAfter you turn on the CE150, the LEDs follow this start-up sequence:1. On the AC Power Module (slot 7), the Module StatusLED is lit with a green color.2. As power is applied, Module Status LEDs on the BufferControl Module and on the SDSL Modules cycle asfollows:Red for ½ secondOrange for ½ secondGreen for ½ second.3. Normal Start-up:After the cycle described in Step 2, the Buffer ControlModule Status LED turns red, and then begins toblink. As the initialization process ends, usually takingless than a minute, the status LED changes to arapidly flickering green. On the SDSL Modules, theModule Status LEDs turn amber while software isbeing downloaded to them from the System ControlModule, then switch to steady green.If software is being installed:After the cycle described in Step 2, the status LEDsturn a steady amber until the software downloadbegins. While the software download is in progress, theBuffer Control and DSL Module status LEDs turn to ablinking amber.When download is complete, the SDSL Module statusLEDs turn green; the Buffer Control Module statusLED changes from amber to rapidly flickering green.4. The System Control Module and System ControlModule-3 have six LEDs beside the Ethernetconnector. When power is applied, the Power LEDimmediately turns green, and the Processor Runningindicator turns green within a second or two.&RSSHU(GJH,QVWDOODWLRQDQG2SHUDWLQJ*XLGH
