Installation Instructions, or BDVNB 101 01/3
zRemove any circuit boards in the three slots next to the side of the existing cabinet that is going up against the new cabinet. For our example, this would be slots 48, 52, and slot 56. Remember what you pulled out and label them.
zRemove the (3) termination resistors, R201, R202, and R207, from the right hand side of the backplane. Refer to Figures
zRemove the knockout plate from the right hand side of the existing cabinet. See Fig.
zTake the remaining two metal shielding gaskets from the installation kit, NTMNB 101 05, and insert them into the hole whre the knockout plate was.
Mount the new cabinet
zHang the new cabinet on the bracket on the wall. Position it to the right hand side of the bracket. This should give you enough room between the brackets so that the shielding brackets do not interfere with each other as you set the new cabinet against the wall.
zOnce the new cabinet is on the bracket, push it up against the existing cabinet as close as possible. This will compress the fingers of the shielding gaskets.
zWhile holding the new cabinet up against the existing cabinet, mark the location of the two mounting holes on the bottom of the new cabinet.
zDrill the holes and secure the new cabinet to the wall with screws.
zRemove the green ground wire from the installation kit, NTMNB 101 05, and connect it between the grounding plates of the new and existing cabinets. See Figure
zTake the flat ribbon cable from the installation kit, NTMNB 101 05, and feed it GENTLY through the knockout holes between the cabinets. The connectors on this cable are keyed. Look at the cable before you feed it through. Make sure you have it oriented correctly.
zGently seat the connectors into the backplane connectors.
zPlace the circuit boards that you previously pulled out of the existing cabinet back into the correct slots in the existing cabinet.
zMount the power supply(s) for the new cabinet.
zConnect the power supply(s) to the cabinet.
zTurn the power supply(s) on and verify the presence and polarity of voltage on the terminal block on the bottom of the cabinet.
If you have not previously tested the cabinet and verified that it powers a board correctly, now is the time to do it.
zInsert a circuit board into the cabinet in any slot. Turn the cabinet power switch on. If everything is all right, then a green LED at the very top of the circuit board should be lit. Ignore any other LEDs.
zTurn off the cabinet power switch and remove the circuit board.
zPlace the circuit board(s) for this cabinet in the correct slot(s).
Powering the system back up
zTurn the power switch for the new cabinet on.
zTurn the power switch for cabinet #1 on.
zThe system should initialize as it did when it was single cabinet system, but you should see the lights on the card(s) in the second cabinet turn on and off also.
zConnect the maintenance PC to the system and log onto the CSMW.
zVerify that the CSMW shows the boards in both cabinets.
zDo a system back up. Give it a new name.
