TRADE SECRET INFORMATION 

5  Place the old board in the antistatic packaging for shipment. 
6  Using the breakers on the PDU, turn up the BIC, AIC and RBS 1 (and RBS 2 if 

present), and then verify that the components are operational before proceeding. 

Wait approximately 3 minutes for the following indicators: 

ƒ

  RBS: The STATUS LED for each group will turn green in this order: A, B and then C.  

ƒ

  RBS: The RADIOBLADE TRANSCEIVER STATUS LEDs will turn red and then green 

for each present RadioBlade transceiver. If no RadioBlade transceiver is present, the 
LED will not light. To verify the contents of the RBS, pull out the shelf (powering off is 
not required) and inspect the RadioBlade transceivers and their respective status 
LEDs. Reinsert the RBS. To do this, press up on one side rail locking arm and press 
down on the other side rail locking arm, and then push the unit into the rack. For an 
illustration of the locking arms, refer to Figure 62 on page 94. 

ƒ

  BIC CRIC and AIC CRIC:  The POWER and STATUS LEDs will turn red and then 

green. All other BIC and AIC card LEDs will turn green. 

7  Using the breaker on the PDU, turn up each RF Shelf and then verify that each RF 

Shelf is operational before proceeding. 

The POWER and ALARM LEDs on the front of the RF Shelf will turn green. 

1  Before replacing any card (board), power down RadioFrame Networks equipment in 

the following order using circuit breakers on the PDU: 

ƒ

  ABIC 

ƒ

  RBS 1 (and power down RBS 2 if present) 

ƒ

  RF Shelves 1, 2 and 3 

2  Always use a static grounding wrist strap before handling any board—do not attach 

the wrist strap to any painted surface on the chassis unit.  

Note:  The ERTM you remove from the BIC or AIC may appear slightly different from the 

replacement ERTM. The current-revision ERTM—labeled “ERTM ASY 0562 XX”, 
where XX ≥ 06—is used in either the AIC or BIC and is configured by means of a 
switch (step 4). The down-rev AIC ERTM faceplate is labeled “PERTM ASY 0560 
XX”, and the down-rev BIC ERTM is identified “ERTM ASY 0562 XX”, where XX ≤ 
05. These down-rev ERTMs do not have a switch on the circuit board and therefore 
cannot be swapped from one type of interface chassis to the other. 

3  Facing the rear of the BIC or AIC, remove the ERTM that is to be replaced following 

these guidelines: 

ƒ

  Loosen the blue knurled knobs on both sides of the board. 

ƒ

  Pull firmly on the tabs located on the bottom of the ERTM you are replacing. 

ƒ

  Gently slide the ERTM straight out and away from the chassis unit so as not to 

damage any components contained on the board. 

4  Remove the ERTM from its antistatic packaging and insert it into the chassis unit as 

shown in Figure 58, and follow these guidelines: 

ƒ

  Check that the ERTM switch is in the correct position for the application. The switch is 

located on the components side of the ERTM circuit board, near the connector 
labeled “POWER”. Appropriate settings are: 
  A—for ERTM inserted in AIC 
  B—for ERTM inserted in BIC.  

ƒ

  Do not jam the board in any way while inserting it.
