A fault has occurred with a component on the E-MSM720. The Status LED
for the component with the fault will flash simultaneously.
On briefly after the E-MSM720 is powered on or reset, at the beginning
of E-MSM720 self test. If this LED is on for a prolonged time, the E-
MSM720 has encountered a fatal hardware failure, or has failed its self
test.
The Locator LED is used to locate a specific E-MSM720 in an area full of
other controllers and E-MSM720s. The LED can be set to be on solid or
flash for a specified number of minutes (1-1440). The default is 30 minutes.
Use the command "chassislocate".

The E-MSM720 self test and initialization are in progress after the E-
MSM720 has been power cycled or reset. The E-MSM720 is not
operational until this LED goes off. The Test LED also comes on briefly
when you "hot swap" a mini-GBIC into the E-MSM720; the mini-GBIC is
tested when it is hot swapped.
A component of the E-MSM720 has failed its self test. The E-MSM720
