SANbox-8 Fibre Channel Switch
3-6 Diagnostics/Troubleshooting 59008-03 Rev. A Installer’s/User’s Manual
Switch ASIC Test Failure (6 Blinks)
The Switch is not operable. The Switch ASIC Test verifies the base functionality of
each Switch ASIC. This includes the control port interface and all functions that
can be performed within the confines of an individual ASIC. A failure indicates a
faulty Switch ASIC and blinks the Heartbeat LED six times between three-second
pauses. The Switch disables the ports associated with the bad ASIC and blinks
their Logged-in LEDs. An ASIC that fails this test could affect the operation of the
remaining ports.
GBIC Bypass Port Loopback Test Failure (7 Blinks)
The Switch is operable. The GBIC Bypass Port Loop-Back Test verifies (on a port-
by-port basis) the ability of each Switch ASIC to loop data out through the Serdes
chip on a port and back to the ASIC control port (bypassing the GBIC). A failure
indicates either a faulty Switch ASIC or an ASIC to Serdes interface problem and
blinks the Heartbeat LED seven times between three-second pauses. The Switch
disables the failing port or ports and blinks their Logged-in LEDs. The ports whose
Logged-in LEDs are not blinking have passed the test and are all usable.
Fibre Channel Port Loop-back Test Failure (8 Blinks)
This test runs in Continuous Test only. Continuous Test is controlled by the
Test Mode switch. Use this test only under the direction of QLogic Customer
Support or your authorized maintenance provider. They will tell you how to
activate this test.
The Switch is not operable while in Continuous Test. In Continuous Test mode, the
Switch Fibre Channel Port Loop-Back Test verifies the ability of each Switch ASIC
to loop data out through each Fibre Channel port, through a loopback plug, and
back to the ASIC control port. In order to accomplish this test, you must attach a
loop-back plug to each GBIC as you test it. QLogic supplies one loopback plug of
each GBIC type that you ordered. Therefore you will be able to test the GBICs one
at a time.
To test:
1. Place the chassis into Continuous Test.
2. Remove all GBICS from the chassis except the one you want to test.
The GBIC under test may be in any port. The Continuous Test will skip
all empty ports.
3. Insert a loopback plug into the GBIC.
4. Cycle the chassis power to cause a reset.
