RE: Factory Reset for EXP40
(08-17-2013 07:40 PM)Boolah Wrote:  How can I do a factory reset of the EXP40? I recently upgraded my T46G from firmware version to version and performed a factory reset of the T46G.

However, after doing the reset, some of the BLF lights on the EXT40 were still lit, while some were completely out (even though all keys were cleared in the web interface and all keys on the LCD were blank). After re-entering all of the DSS keys on the EXT40 (I have all 40 keys on the EXP40 set to BLFs), some of them show correct BLF status while others don't. Some will continuously show red (whether the extension is in use or not), some will continuously show green (again, whether the extension is in use or not), and others will not show any status at all (the light will be out completely). What's even more perplexing is that some BLFs will work just fine, showing correct status.

I've reset to factory defaults on the T46G twice and see the same issue. Between the two resets, different BLFs worked/didn't work, so I wouldn't imagine it's has anything to do with the specific extensions being monitored by the BLFs. Moreover, non-Yealink phones are monitoring the same BLFs without issue. Perhaps there is some incompatibility between the new firmware for the T46G ( and the existing firmware for the EXP40 (

Is there something which needs to be done to reset the EXP40 to factory defaults other than resetting the T46G to factory defaults?

Hi Boolah,
I tested at our side, after reset to factory default, yes, EXP40 is still lighting BLF LED.
Did you try reconnect EXP40 after this? Here after i reconnect EXP40, everythink works well.
And after reset, the "LED Off in Idle" will enabled by default, so you still need to disable this in the webpage-Features-General information, so BLF will light green when it's idle.
Any update please let us know, thanks.
