Removing the Base Radio

Procedure:
1 Remove power from the MTS by switching off the Power Supply Unit.
NOTICE: To perform a hotswap of a Base Radio, do not turn off the Power Supply.
Connect a terminal to the Service Port and log in. Make sure the Base Radio is not
transmitting by entering the MMI command:
• From the Base Radio Core or Boot1 use: dekey
• From the Test Application use: power -otxch1 -a0.0
For more information on this command, see MMI Commands Manual.
2 Unplug the cables at front of the Base Radio.
3 Remove the TORX screws securing the faulty module to the chassis; these are located on the
top and bottom of the front plate of the faulty module. Save the screws for reuse.
4 CAUTION: The module can be very hot. To avoid injury, allow the module to cool down
before servicing.
Pull out the module.
