Group A LEDs display the pass and fail counts when the
module is in diagnostic mode. Group B LEDs display codes if
a module error occurs during normal operation. Additionally,
in redundant configurations, they show which module is the
primary and which is the secondary. Group B LEDs seven
and eight are on if the module is primary; group B LED eight
is on if the module is secondary. If an error occurs, the MFP
status LED turns red and the group B LEDs light up to dis-
play the error code (Table
). Note that both groups of LEDs
one through eight are on when the system is first coming up.
This is normal. It means that the module is not yet on-line.
