I have a Nortel Option 81C. What are the steps neccessary to take down a system utilities card for replacement? I think I have to split the core and a few other things. Any advice will be appreciated.

Hi Paulsraptor; there is a Nortel: CS1000 (Meridian) systems forum where you can get more assistance, although I do work tier II/III support on Nortels...
The procedure is fairly simple; here's the cut/paste of the maintenance NTP. If done right, you won't even affect service, except possibly when you swap cores - but usually that's pretty seamless.
Replace the NT4N67 cPCI System Utility (SYS UTIL) card
1. Check that the Core containing the SYS UTIL 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 is active, switch cores in LD 135:
LD 135 To load the program.
SCPU Switch Core (if necessary).
2. In LD 135, split the CPU Cores:
SPLIT
3. In LD 135, on the inactive CP, software-disable the SYS UTIL card:
DIS SUTL c 15 Disable the SYS UTIL card, where:
c = Core number (0 or 1)
This software-disables both the cCPI System Utility
card and its associated cCPI System Utility Transition
card.
4. Hardware-disable the SYS UTIL card.
Set the faceplate switch to DIS.
5. Use a small-bladed screwdriver to remove the screws from the SYS UTIL card.
6. To remove the card, hold the card by the faceplate latches and gently pull it out of
the slot.
7. To install the replacement card, hold the card by the faceplate latches and gently
push it into the slot until the connectors make contact with the backplane.
8. Gently push the latches forward to set the card and lock it in place.
9. Use a small-bladed screwdriver to replace the screws on the card.
10. hardware-enable the SYS UTIL card: set the faceplate switch to ENB.
11. In LD 135, software-enable the SYS UTIL card:
ENL SUTL c 15 Enable the SYS UTIL card, where:
c = Core number (0 or 1)
This software-enables both the cCPI System
Utility card and its associated cCPI System Utility
Transition card.
12. In LD 135, check status:
STAT SUTL c 15 This checks the status SYS UTIL status where:
c = Core number (0 or 1)
This checks the status of both the cCPI System
Utility card and its associated cCPI System
Utility Transition card.
13. In LD 135, on the active CP, rejoin the two CP PII cards:
