3.4.5.3 500-25 Network Card Indicators and Switches
• 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.
