Procedure 2:
Replace the NT4N68 cPCI System Utility Transition
(SYS UTILTRANS) card
To replace a System Utility Transition Card, you must software and hardware
disable the NT4N67 System Utility card associated with the NT4N68 System
Utility Transition Card. You must disable the System Utility card from the
inactive core.
1 Check that the Core containing the SYS UTIL TRANS card to be
replaced is inactive:
a. The LCD/LED display panel across the top of the Core/Net
module core cards has two rows of LEDs.
If either of the LEDs (top = red or bottom = green) is on for any of
the cards, that side is in a test or idle state.
b. If the Core containing the SYS UTIL TRANS card is active, make
the other Core active:
LD 135
SCPU
2 In LD 135, split the CPU Cores:

card: set the faceplate switch to DIS.

faceplate of the SYS UTIL TRANS card.
7 At the back of the module, use a small-bladed screwdriver to remove
the screws, located on the top and bottom of the SYS UTIL TRANS
card cards. Be careful not to drop the screws into the Pedestal. Refer
