3.1
Replacing a Transceiver
CAUTION.
In a non-protected system, this procedure
will affect traffic. In a protected system, ensure
locking traffic on the available channel during maintenance.
Remove the Transceiver
•
Push the PWR button
OFF for at least 3 seconds, until the PWR LED is Off.
NOTE.
This ensures that there are no sparks at the DC power connectors when
removing DC from the transceiver. The controller is part of the transceiver. If the
DC power of the replacement transceiver was turned OFF by pushing the PWR
button before, you need to push that button again to turn ON the DC power to the
newly installed replacement transceiver. However, if that transceiver was turned
OFF by disconnecting the DC power source before, connecting the DC power source to the
replacement transceiver will turn ON the transceiver power supply immediately.
