Removing the test setup
After acceptance testing has been completed and the results show that the
system is operating correctly, remove the setup used to conduct the testing
and restore equipment according to the customer configuration.
If the actual customer configuration was used to perform these tests, it is
not necessary to change or remove the setup.

Action
Unplug the power connector on the Fiber Remote Multi-IPE
Interface unit I/O panel.
Observe that all LEDs on the unit are OFF.
Reinstall the power source connector into the Fiber Remote
Multi-IPE Interface unit I/O panel power connector.
Observe the LEDs.
The Power LED on the Fiber Remote Multi-IPE Interface should
come ON and stay ON upon completion of a successful self-test.
Press the Reset button to turn OFF the alarm LEDs.
They should turn OFF and stay OFF if the fiber-optic link
recovered from the power failure.
Place a call across the link to verify its operation.
Place the MMI terminal in the Host SDI mode and load the LD 60
overlay to switch the system clock controller from 0 to 1.
Alternatively, place the MMI terminal in the Host SDI mode and
use LD 60 to switch the system clock controller from 1 to 0.
Switch system clock from active to standby by executing the
SWCK command.
Get the status of the system clock 0 or 1 by executing the SSCK
0, 1 command.
Check the established call(s) and make sure they have not been
dropped.
If the call(s) are not established, the Phase-Lock-Loop (PLL) is
out of lock due to clock switching. The status message can be
XM1000 to indicate a problem and PLL is unlocked.
Find the problem and reestablish the PLL lock.
