Troubleshooting 

1.  Make sure the board is securely seated in the slot. 
 

2.  Observe the LED’s. Each port on the ZX478 has a LINK (green) LED and an ACTIVITY 

(amber) LED. The green LED illuminates upon successfully establishing a link. The amber 

LED illuminates during transmit/receive activity. Note: In most cases, the driver must be 

properly loaded and configured to bring up the link. It is off if there is no link established.  

 

Each ZX478 also has LED's for Power, Operational, Internal and External fault indicators. 

The status LED is duplicated on both the front and rear panels. The front panel also 
includes an LED indicating continuity with the Rear-Transition Module. The front panel 

also includes the industry-standard blue LED next to the bottom Hot-Swap ejector tab. The 

LED's are defined by the following table: 

 

Power Green 

ON 

indicates 

power. 

Operational 

Green 

ON indicates driver loaded and 

board has passed internal tests. 

Rear Panel 

Green 

ON indicates electrical 
continuity between adapter and 

rear-transition module. 

Internal Fault 

Amber 

ON indicates a failure of the 
internal tests. 

External Fault 

Amber 

ON indicates a failure external 

to the adapter- inability to 

establish link on a configured 
port, or another connectivity 

problem external to the adapter. 

Hot Swap 

Blue 

ON during removal/insertion 

of adapter, signifying system 

readiness for transition. 

 

 

3.  Refer to operating system specific documentation to evaluate any error messages or logs 

when the driver is loaded.
