Troubleshoot the Daughtercards
Status indicators provide information about the card and the network when you are
connected via the fiber connectors. The following definitions and tables outline the possible
states, explain what each state means to you, and indicate what action you should take, if any,
to correct that state.
Definition of terms:
• steady - indicator is on continuously in the defined state.
• alternating - the two indicators alternate between the two defined states at the same
time (applies to both indicators when viewed together); the two indicators are always
in opposite states, out of phase.
• flashing - the indicator alternates between the two defined states (applies to each
indicator viewed independent of the other); if both indicators are flashing, they flash
together, in phase.
IMPORTANT
Keep in mind that the module status indictor reflects the module state,
for example, self-test, firmware update, normal operation but no
connection established. The network status indicators, A and B, reflect
network status. Remember that the host is able to engage in local
messaging with the card although it is detached from the network.
Therefore, the module status indicator is flashing green if the host has
successfully started the card. Note, however, that until the host removes
reset, all indicators on the daughtercard will remain off.
