System status LEDs
The three LEDs at the bottom of the switch represent the switch status. These LEDs
are the green OK LED, the blue location LED, and the amber switch fault LED.
Table 4 contains a description of each system status LED on the information panel of
the switch.
Fibre Channel external port status LEDs
There are three port LEDs directly to the right of each of the six Fibre Channel
external ports on the front panel of the switch. These LEDs indicate the logged-in,
activity, and fault status of that Fibre Channel external port.
Table 5 contains a description of each port LED on the information panel.

External port
Logged-in (LOG) There are six green external port logged-in (LOG) LEDs. The exter-
nal port logged-in LED is the top LED directly to the right of the cor-
responding port. When one of these LEDs is lit, it indicates that
there is a connection (or link) to a device on that port.
External port
Activity (TX/RX) There are six green external port activity (TX/RX) LEDs. The exter-
nal port activity LED is the middle LED directly to the right of the
corresponding external port. When one of these LEDs flashes, it
indicates that data is being received or transmitted (that is, activity
is occurring) on that port. The flash frequency is proportional to the
amount of traffic on that port.
External port Fault
(!)
There are six amber external port fault (!) LEDs. The external port
fault LED is the bottom LED directly to the right of the correspond-
ing external port. When an external port fault LED is lit, it indicates
that the external port has failed the internal, external, or online port
diagnostics tests that are performed with the QuickTools interface
application or CLI.
