Sys A
Indicates that the Firebox is running from its primary user-
defined configuration.
Sys B
Indicates that the Firebox is running from the read-only factory
default system area.
Power
Indicates that the Firebox is currently powered up.
Security Triangle Display
Indicates traffic between Firebox interfaces. Green arrows briefly
light to indicate allowed traffic between two interfaces in the
direction of the arrows. A red light at a triangle corner indicates
that the Firebox is denying packets at that interface.
Traffic
A stack of lights that functions as a meter to indicate levels of
traffic volume through the Firebox. Low volume indicators are
green, while high volume indicators are yellow. The display
updates three times per second. The scale is exponential: the first
light represents 64 packets/second, the second light represents
128 packets/second, increasing to the eighth light which
represents 8,192 packets/second.
Load
A stack of lights that functions as a meter to indicate the system
load average. The system load average is the average number of
processes running (not including those in wait states) during the
last minute. Low average indicators are green, while high average
indicators are yellow. The display updates three times per second.
The scale is exponential with each successive light representing a
doubling of the load average. The first light represents a load
average of 0.15. The most significant load factor on a Firebox is the
number of proxies running.
