When non F5 optics is used for front switch ports, the LCD and /var/log/ltm will display some warning message. But the alarm LED may not reflect that.
The alarm LED may not reflect the warning.
This is caused by a race condition. When a blade comes up and decides its role as a primary blade or a secondary blade, it will clear the alarm LED. So the last blade coming up may have its alarm LED in the right state, but the blades that came up earlier may have their alarm LEDs cleared.
The problem is fixed in TMOS v12.1.1.
