D1 and D2 will, under normal operation, flash at 1Hz and 2Hz respectively. If there is a problem during start-up, one or both LEDs will flash considerably faster.

D13 should be on under normal operating conditions. The LED turns off when data comes in from a remote link but the off duration is very short and not visible. It is therefore only useful to show an error condition.

D20 is turned on just after power-up then turned off under TDM control shortly afterwards. The LED is also on during a TDM reconfiguration process. The state of the LED is duplicated on a remote 500-25 if connected directly.
