Preliminary
Cable Continuity Tests
SANbox-8 Fibre Channel Switch
3-8 Diagnostics/Troubleshooting 59008-03 Rev. A Installer’s/User’s Manual
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.
Cable Continuity Tests
When there is a problem communicating over a particular link and both the Switch
and the N_Port adapter pass their respective tests, check the continuity of the
cables.
If possible, swap another set of cables into the faulty link.
Did this correct the problem?
Yes Replace the faulty cable.
