NOTE: When VD-4510c is installed in the VD-4000r or VD-4000z chassis, the power button
LED indicator status may be delayed for up to two minutes while the sled is initializing. The
power button LED will start slowly blinking to indicate the system is performing the power on
sequence after this time period.
