PRELIMINARY
f
Primary and Redundant AC Power Input switches — For BME 0 to recognize
all of the BMEs in the daisy chain, BME 0 may not be powered on before the
other BMEs. Rather, turn on BME 0 at the same time or after the other BMEs.
N
During shipment, circuit cards can become dislodged from their edge connectors
during shipment. Reseat all I/O and controller cards before initial power up.
See chapter 6, “Upgrades and Maintenance”, for the applicable procedures.
Toggle the Primary AC Power Input switch to the on () position to power up
the BME.
If this BME is equipped with redundant power supplies A and B, toggle the
Redundant AC Power Input switch to the on () position.
g
Power Supplies LEDs — On power up, observe that the +V and -V Primary
LEDs light to indicate that the supplied power is within
tolerance.
If this BME is equipped with redundant power supplies
A and B, on power up, observe that the +V and -V
Redundant LEDs light to indicate that the supplied
power is within tolerance. If the primary A or B
power supply fails, the Primary LEDs go out and the
Redundant LEDs blink to indicate that the redundant B
or A power supply is supplying the load.
h
CPU Status LEDs — On power up, observe that the Primary CPU Status LED
blinks initially to indicate that internal startup
housekeeping is occurring and then, assuming that the
primary controller is the active controller, blinks to indicate
that the primary controller is ready.
If this BME is equipped with a redundant controller
card, observe that the Redundant CPU Status LED blinks
initially and then, assuming that the redundant controller
is the standby controller, lights steadily to indicate that the
redundant controller is ready. If the primary controller fails,
the Primary CPU Status LED goes out and the Redundant
CPU Status LED blinks to indicate that the redundant
controller is the active controller.
N
Both LEDs blink at startup. After startup, the LED for the active controller
blinks and the LED for the standby controller lights steadily.
