Installer’s/User’s Manual 59005-03 Rev. A Diagnostics/Troubleshooting 3-11
Switch Auto-Route Test Failure (10 Blinks)
The Switch is operable. The Switch Auto-Route Test verifies the auto-route
capability of individual ports to automatically route frames to the other ports in the
chassis. A failure indicates an inability to successfully route frames between a port
pair and blinks the Heartbeat LED ten times between three-second pauses. The
Switch disables the failing ports or port-pairs and blinks their Logged-in LEDs.
The ports whose Logged-in LEDs are not blinking have passed the test and are all
usable.
11 Blinks— Not used.
12 Blinks — Not used.
Arbitrated Loop Test Failure (13 Blinks)
The Switch is operable. The Arbitrated Loop test verifies the ability of the Arbitrated
Loop ports to initialize properly. A failure indicates the inability to successfully
initialize an Arbitrated Loop (FL) port and blinks the heartbeat LED 13 times
between three-second pauses. The Switch disables the failing ports and blinks their
Logged-in LEDs.
The ports whose Logged-in LEDs are not blinking have passed the test and are all
usable.
Switch Management Port Failure (14 Blinks)
The Switch is operable. The Switch Management Port test verifies the integrity of the
Ethernet data bus functionality. A failure indicates that communication over the
Ethernet port will most likely be adversely affected when this failure is indicated.
The Heartbeat LED will blink fourteen times between three-second pauses. No
port Logged-in LEDs blink.
The remainder of the Switch and all ports have passed the tests and are operable.
NVRAM Test Failure (15 Blinks)
The Switch is not operable. The Non-Volatile Memory (NVRAM) test verifies the
status of the NVRAM battery (not low), performs a checksum on any existing data,
and performs a data write/read test on the unused areas of the NVRAM. A test
failure in any of the above three tests will blink the Heartbeat LED 15 times
between three-second pauses.
Hung Flash Control Code
The Switch is not operable. If the Power Good LED is lit and the Heartbeat LED and
the remaining front-panel LEDs all blink in unison, the Flash control code running
the processor is hung.
Complete Failure
The Switch is not operable. If the Power Good LED is lit and the Heartbeat LED does
not blink at all (always ON or always OFF) the Switch is not operable.
