Setting Up and Testing the MAX Hardware
Interpreting the MAX LEDs
MAX back-panel
Figure 2-11 shows the MAX back-panel LEDs, which display the status of the Ethernet–
interface.
Figure 2-11. Ethernet interface LEDs on MAX back-panel
Note: The MAX Classic back-panel has similar LEDs on the Ethernet expansion card if one
is installed. The MAX Classic has one LED for each possible Ethernet interface (10Base-T,
and COAX (10Base-2), which illuminate when the interface is in use. The ACT and COL
LEDs are the same as those on the MAX 6000.
Table 2-3 describes the Ethernet-interface LEDs.
Once you are familiar with the MAX LEDs, you are ready to start up the MAX.
