Thresholds
M1 System Management Board User’s Guide 37
• Lo-Warn is a local minimum, which produces a YELLOW light if breached.
• Hi-Warn is a local maximum, which if passed also produces a YELLOW light.
• Hi-Limit is the absolute maximum, which produces a RED light if breached.
When the thresholds are set between Lo-Warn and Hi-Warn, a green light indicates that the board is operating at
optimum levels between these two points.
The shaded boxes on the right display the exact threshold values for the Lo-Limit, Lo-Warn, Hi-Warn and Hi-Limit.
The Range-Lo and Range-Hi panels indicate the extreme far right and far left of the colored lines. None of these
shaded boxes can be changed manually and can only be set by the slider markers.
See “Setting Thresholds” on page 39 for more information about setting threshold limits in the Threshold tab and in the
Graphs tab.
