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

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.
7.9.3.3 ERTM
1 Before replacing any card (board), power down RadioFrame Networks equipment in
the following order using circuit breakers on the PDU:
ABIC
RBS 1 (and power down RBS 2 if present)
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:
Loosen the blue knurled knobs on both sides of the board.
Pull firmly on the tabs located on the bottom of the ERTM you are replacing.
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:
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.
labeled “POWER”. Appropriate settings are:
A—for ERTM inserted in AIC
B—for ERTM inserted in BIC.
Do not jam the board in any way while inserting it.
