c At the confirmation screen, click OK.
The base radio halts activity in the current mode and switches operation to the requested
mode.
7 Optional: If you choose to turn off the power, set the rocker switch on the front of the associated
power supply to the Off (O) position.
NOTICE:
It is not necessary to turn off the power supply for the transceiver module being replaced,
as the modules can be swapped out with the power on.
8 Disconnect the Ethernet cable from the service port on the transceiver being replaced.
9 Remove the fan assembly to gain access to the transceiver module. See
Assembly on page 237.
IMPORTANT: Although the transceiver module can be swapped out without shutting the
power off, minimize the amount of time the fan assembly is removed so the circuitry that
remains powered on does not overheat and shut down.
10 Label and disconnect all cables from the ports on the transceiver.
11 Using a T20 bit, loosen the two captive screws on the front of the transceiver module to
disengage them from the chassis.
12 Using the handle, gently pull the transceiver module straight out along the guides on which it
sits.
13 Slide in the replacement transceiver module along the guiding rails until it is engaged. A slight
push may be needed to securely engage the module.
IMPORTANT: If the transceiver module stops well before it is engaged, it is in an
incorrect position. Either it is in the wrong slot or it is rotated 180°. The module has a
keying feature that prevents it from going all the way into an incorrect slot, or going into
the correct slot but rotated 180°. Do not try to force the module.
LEDs on the transceiver turn on when it is engaged.
14 Using a T20 bit, tighten the two captive screws on the front of the module to secure the
transceiver module to the chassis.
15 Reconnect all cables to the ports on the transceiver.
16 Reinstall the fan assembly. See
17 Optional: If you chose to turn off the power, set the rocker switch on the front of the associated
power supply to the On (I) position.
18 Perform basic device configuration in CSS using the serial port. See
Serial Port Link on page
a Set the IP Address and BR_CM Pairing Number for the device. See
Address and Pairing Number in CSS on page
b Set the Serial Security Services. See
138.
19 On systems with MAC Port Lockdown implemented, disable MAC Port Lockdown if the device
being replaced is a colocated base radio, at a repeater site or simulcast site. The switch port
where the colocated replacement device is connected to needs to be Unlocked before
connecting with CSS or performing a software download. See the MAC Port Lockdown manual
for instructions on how to disable MAC Port Lockdown.
