LED indicators on RB750 and on RB750G

Hello,
I would like to ask, maybe silly question, why LED indicators for Fast Ethernet ports doesn’t blink when they are active on RB750, but on RB750G LEDs for Gigabit Ethernet ports indicate current state - send and receive. Anyone has a answer? I cannot figure this out…

Thanks for your time.

rb750 is made that way. LEDs do not show link activity, just if the link is active.

Thanks for reply. I thought that something is wrong with boards - tested about 10 RB750 and same amount of RB750G with same result.
