LED Colors and Their Meanings
Chapter 6144
— The adapter is bad.
— The cable is bad.
— The switch port is bad (if the adapter is connected to a switch).
Note that if a switch port is bad, and (for some reason) you
cannot use a different port on the switch, you must replace the
switch module in the HF2 switch (whichever is applicable).
However, you first should try turning the switch’s power off and
then back on.
— The adapter is connected to a non-operational adapter in the
remote node (in a node-to-node configuration).
✓ If the connection from the adapter to the corresponding switch port
(if a switch is used) or the corresponding adapter in the remote node
(in a node-to-node configuration) is operational, the
“Connected/Traffic”, “Link” or “Link Connected/Traffic” LED on the
adapter shows as solid green.
✓ If data is flowing between the adapter and the switch port (if a switch
is used) or the corresponding adapter in the remote node (in a
node-to-node configuration), the “Connected/Traffic”, “Link” or “Link
Connected/Traffic” LED shows as flashing green. Note that data does
not start to flow until HyperFabric initialization has occurred (see
“Using the clic_init Command” on page 79).
✓ If the adapter is in an error state that requires it to be replaced, the
“Error” LED on the adapter shows as solid yellow. See “Replacing a
HyperFabric Adapter” on page 156 if you need to replace an adapter.
Table 6-2 below summarizes the adapter LED information in a table
