Information
Each NIC has two LEDs:
• The upper LED shows that the network cable is connected.

Information
The five LEDs at the top of the MPB16-4 board are visible through

If these LEDs are not on after the system has booted to the
operating system and the diagnostic screen has started, then
one of the following conditions can be present:

The three red LEDs at the top of the MPB96 board are visible

the system. If this LED stays on after the startup, the card is
