The HW400c/2 includes eight on-board LED
Ethernet ports. The LEDs are labeled L0-L8 
connector J5. 
 
The BCM5388 has a serial LED interface, fro
be xtracted.  The serial LED signal is routed to

hine that decodes the LED states for each port.  The eight status LEDs on the top 

m
edge of the HW400c/2 board can be configured to show the status for all eight 
Ethernet ports.  Each status LED gives the status for its corresponding port in the 
Link/Activity/Speed format.  The CPLD LED registers control the selection of 
Ethernet status, boot status, or general debug modes for the eight LEDs. 
The serial LED interface signals are also routed to the RTM through CompactPCI
connector J3.  
 
 
 

LEDMODE settings on the BCM5388 are hardwired to “101” (see Serial
