The LB cabinet AC/DC power should be turned on in the following sequence: 
 

1.  Switch ON the MAIN PDU circuit breaker. 
2.  Switch ON the HE circuit breaker (CB 5), located on the PDU. 

o

 

The air-to-air heat exchanger/heater will not turn on if the DRU is at room 
temperature.  Once the electronics compartment doors are closed, and the 

compartment temperature increases, the air-to-air heat exchanger/heater fans will 
turn on. 

3.  Switch ON the LBE rear panel power switch. 
4.  Switch ON the TRMS rear panel power switch and close the electronics compartment 

rear door. 

5.  Switch ON the TRMS circuit breaker (CB 8), located on the PDU front panel. 

o

 

Ensure that the TRMS Power LED is illuminated green. 

6.  Switch ON the FAN 1 / FAN 2 (CB 9) and the FAN 3 / FAN 4 (CB10) circuit breakers, 

located on the PDU. 

o

 

Ensure that the HPA compartment fans are rotating continuously (fans can be 
heard) and that the PDU FAN 1 / FAN 2 and FAN 3 / FAN 4 LEDs are illuminated 
red to indicate current draw. 

7.  Switch ON the LBE 25A circuit breaker, located on the BMS front panel. 

o

 

Ensure that the LBE Power LED is illuminated green and that the internal fan is 

rotating continuously.  Note: Fan operation will be halted momentarily during the 
boot-up process, but will continue to operate continuously. 

8.  Switch ON the TSC-L 5A circuit breaker, located on the BMS front panel. 

o

 

Ensure that the LED’s on the LB HPA’s begin to flash red and green alternately. 

9.  Switch ON the SPARE 2.5A circuit breaker, located on the BMS front panel. 

o

 

Ensure that the BMS alarm LEDs are no longer illuminated red; only the CTR LED 
should be illuminated green. 

10. Switch ON the HPA 1 PSU circuit breaker (CB1), located on the PDU. 

o

 

Ensure that the HPA 1 PSU (PS 1) Norm LED is illuminated green. 

o

 

Ensure that the HPA 1 front panel LED is illuminated blue. 

11. Switch ON the HPA 2 PSU circuit breaker (CB2), located on the PDU. 

o

 

Ensure that the HPA 2 PSU (PS 2) Norm LED is illuminated green. 

o

 

Ensure that the HPA 2 front panel LED is illuminated blue. 

12. Switch ON the HPA 3 PSU circuit breaker (CB3), located on the PDU. 

o

 

Ensure that the HPA 3 PSU (PS 3) Norm LED is illuminated green. 

o

 

Ensure that the HPA 3 front panel LED is illuminated blue. 

13. Switch ON the HPA 4 PSU circuit breaker (CB4), located on the PDU. 

o

 

Ensure that the HPA 4 PSU (PS 4) Norm LED is illuminated green. 

o

 

Ensure that the HPA 4 front panel LED is illuminated blue.
