SRX5600 Services Gateway DC Power Supply LEDs
Each DC
power supply faceplate contains three LEDs that indicate the status
of the power supply (see Table 1). The power supply status is also reflected in two LEDs on
the craft interface (see ). 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.
