5 At the > prompt in LD 32, type ENLC c and press the Enter key to
enable the MISP.
If the Dis LED on the MISP extinguishes, the MISP is functioning
correctly and is ready to process calls.
The SILCs and UILCs can be removed from and inserted without turning off
the power. This allows the system to continue processing calls on functional
SILCs and UILCs.
Note: In the case where an ISDN BRI trunk connected to the card is
providing a reference clock source to the system clock controller, the
reference source must be reassigned to another location. Refer to the
chapter entitled ISDN BRI trunk implementation for more information
about the clock controller source.
To remove an SILC or UILC:
1 Log-in on the maintenance terminal or telephone and load overlay
program 32 (LD 32).
Note:
Make sure the MISP is idle before proceeding with the next step
to avoid interrupting active calls.
2 Type DISI c and press the Enter key to disable the SILC or UILC,
where c is the MISP card slot number.
Note:
The DISI command waits until all units on the card are idle be-
fore disabling it. You may also use the DISC command, however, all
calls associated with the card will be disconnected.
3 Remove the card.
Place it in an antistatic bag away from the work area.
4 Insert and secure the replacement card in its card slot.
The card automatically starts a self-test.
Observe the red LED on the front of the card. It is lit during the test. If it
flashes three times and stays lit, it has passed the test. Go to step 9. If it
does not flash three times and then stays lit, it has failed the test.
