LED Indicators
This chapter describes the distribution chassis LED indicators and what they mean.
Power LEDs
COLOR MEANING
Green Power supply is good.
Red One of the power supplies has failed. This condition will only
exist in a unit with redundant power supplies.
Off The redundant power supply is not installed.
Input LEDs
The operation of these LEDs depends on the
switchmode
and
disablemode
settings (see Chapter
3 - Control and Status Commands
). The switchmode command determines whether a particular
Signal Input should be present or not. For example, if switchmode=a then Signal Input B need not be
present.
COLOR MEANING
Green The signal input is selected as the current input.
Red The signal input should be present but it is not. See
switch-
mode
to determine whether a signal input should be present or
not.
Flashing Red The signal input should be present but its corresponding disable
input has been enabled (see
disablemode
) and is asserted.
Yellow The signal input is present but is not selected as the current
input.
Flashing Yellow The signal input is present, but should not be (see
switch-
mode
) and its corresponding disable input has been enabled
(see
disablemode
) and is asserted. This usually occurs only
when the user has configured the system incorrectly. For
example, a secondary input has been connected and its dis-
able input has been enabled but
switchmode
is configured as
switchmode=a
or
switchmode=b
.
Off The signal input is not present and should not be present per
switchmode
.
