Migration tasks
Issue 2.1 June 2006 463
Note:
Note: If you replace a TN795 Processor circuit pack, you might not need the TN744D/E
Call Classifier-Detector circuit pack. The TN2312BP IPSI circuit pack has call
classifier functionality. However, increased voice and data traffic can require the
TN744D/E Call Classifier-Detector circuit pack.
Note:
Note: If you have a TN799C or earlier C-LAN circuit pack, you must replace the circuit
pack with a TN799DP C-LAN circuit pack.
Turning off the power to the control cabinet
!
CAUTION:
CAUTION: Ensure that you have completed the premigration administration. If you do not
perform the premigration administration, the system will not function. For more
information, see Migrating translations
on page 814.
To turn off power to the control cabinet:
1. On the faceplate of the processor, press and hold the shutdown button until the shutdown
process starts.
When you see the green light the system is shut down.
!
DANGER
:
DANGER: The latch on the power supply acts as the DC power switch and removes only DC
power from the backplane. To remove the AC power from the cabinet, pull the AC
power cord from the back of the cabinet.
2. Unplug the power cord from the back of the cabinet to turn off the cabinet.
Replacing the processor circuit pack
To replace the processor circuit pack:
1. Remove the entire processor circuit pack.
2. Place the circuit pack in an antistatic carrier or bag. You might need to reinstall this circuit
pack if you must stop the migration.
3. Remove the TN2182 Tone Clock circuit pack.
