MX240 DC Power Supply LEDs
Each DC power supply faceplate contains three LEDs that indicate the status of the
power supply (see Table 56 on page 94). The power supply status is also reflected in
two LEDs on the craft interface (see “Power Supply LEDs on the MX240 Craft Interface”
on page 15).In addition, a power supply failure triggers the red alarm LED on the craft
interface.
NOTE: An SCB must be present for the PWR OK LED to go on.
