MCUs now perform the software updating sequence. The MCU 
with the newest revision of the software will update the other 
MCUs in the system. It is normal to see status LEDs 1, 3 and 4 
blinking to confirm the update. Once the software update starts you 
will see cascading/cycling line LEDs on the MCUs. The update 
may take only a few minutes or longer, depending on the number 
of MCUs installed. Be patient and allow the system to complete 
this update. If the software updated does not start after 15 minutes, 
reboot the system. If issues still persist, please call Polycom 
Customer Support for further assistance. 
5.  After a few moments each MCU in the chain should have a 
unique box ID number (
1
 through 
4
), shown on the 
STATUS
 LEDs. 
If this is not the case, recheck the IPC wiring.  
6.  If the replacement MCU has 
STATUS
 LED 
3
 and 
4
 lit, the 
configuration data has not been successfully shared. Most likely, 
the replacement MCU was powered up before it was correctly 
attached to the IPC chain. Repeat the entire replacement 
procedure. 
Replace a Base Station 
To replace a Base Station, unplug the existing Base Station and plug in 
the new Base Station.  
• 
The LED will blink red and green as the system software 
downloads to the Base Station and the Base Station is tested.  
• 
When the LED blinks amber, the system is ready for operation.  
• 
When the LED blinks green, a handset has established a radio link 
with that Base Station. 
• 
If the LED turns solid red, there should be an error message on the 
MCU’s 
STATUS
 LEDs and the MCU 
ERROR
 LED should be lit.
