4.5  Base Station Will Not Download 

If a Base Station is stuck in download, the LED may flash red and green or just red; the 
status on the Operator’s Console will show 

Reset

 or 

Download

; and the Base Station 

will be locked up (not handling calls). 

1.  At the Operator’s Console, check to see that the Base Station is registered, using 

F2 -

 Port Card Display

.  

2.  Check the status of the Base Station. If the status shows 

Download

 or 

Download

 

Data

, the Base Station has locked up during download.  

3.  To reset the Base Station: From F2, 

Port Card Display

, highlight the Base 

Station and press Enter, then select

 Reset RCU

 from the menu. 

4.  If the Base Station still does not download, try disconnecting power from the Base 

Station and then reconnecting it (unplug the RJ-45 connector on the Base Station 
then plug it back in again, or remove the bridging clips from the demarc block and 
then replace them.)  

5. On the 

Port Card Display

 (F2) screen, select the Base Station in question and 

press Enter to show 

Base Station Detail

. This shows continuous update of the 

Base Station’s status. The 

DL Errors

 field shows the number of Download Errors. 

Any number greater than 0 indicates a problem. 

RCU Link

 shows current 

transmission errors. These errors are generally caused by hardware problems. 
Contact SpectraLink Customer Support for assistance. 

4.6  Base Station LED Flashing Red 

This indicates that the Base Station is not communicating with the MCU. 

1.  Follow the instructions in Base Station LED Flashing Red and Green. 
2.  Be sure there are no bridge taps (“Y”s) on the demarc block. Remove any you 

find. 

3.  If the problem persists, follow instructions in 

Base Station’s LED Solid Red or 

Yellow,

 below. 

4.7  Base Station LED Solid Red or Yellow 

This indicates a short in the Base Station’s transmit or receive wire pairs, usually within a 
pair. 
Be sure none of the wires are shorted together. Remove the RJ-45 connector from the 
Base Station. Remove the cable between the Interface Module and the demarc block. 
Then use an ohmmeter to be sure there is an open circuit between pins on the RJ-45. If 
you do not want to remove the cabling from the Interface Module (so you do not interfere 
with system operation), remove the bridging clips on the demarc block for that Base 
Station, then test with the ohmmeter.
