States
This section describes the different system states of the 7600 Card and 
how they are indicated on the LED display.
System States and
LEDs
The following Table 2-2 lists the system states of the 7600 Card module 
in the first column. The state in which the 7600 Card is currently 
operating is displayed by the system status LEDs. Referring to Figure 2-2, 
these are the three LEDs: P(ower), F(ail), and A(ctive) under the label 
“SYS” on the left side of the LED panel. Table 2-2 shows the correlation 
between the current system state and SYS LEDs.

Table 2-3 also provides information about the system states but is 
organized by system status LED. The meaning of each SYS LED mode is 
described.
