L1 Controller Commands
007-3938-003 65
Used on all bricks.
leds
Use the leds command to read the value of the group 0 and group 1 status LEDs. In
systems that include a C-brick, this command is only valid for the C-brick. These LEDs
connect to I/O expanders that monitor group 0 status LEDs 0 through 15 and group 1
status LEDs 0 through 15. In the output of the leds command, the CPUs correspond to
the status LEDs as follows:
• CPU A corresponds to I/O expander A_0100001x - group 0 status LEDs 0 through 7.
• CPU B corresponds to I/O expander A_0100010x - group 0 status LEDs 8 through
15.
• CPU C corresponds to I/O expander A_0100011x - group 1 status LEDs 0 through 7.
• CPU D corresponds to I/O expander A_0100100x - group 1 status LEDs 8 through
15.
The number next to the CPU letter is a hexadecimal value that represents the value of the
status LEDs that connect to the I/O expander (a bit set to 1 indicates the LED is on, a bit
set to 0 indicates the LED is off). Example 3-37 shows sample output from the leds
command. For systems with C-bricks containing IP41 processors, the output of the leds
command matches the numbering of the CPUs.
