Power-On-Self-Test (POST)
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
useable.
Fibre Channel Port Loop-back Test Failure (8 Blinks) (This test runs in Continuous Test only)
The Switch is operable. 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 installed GBIC (Ancor supplies one loopback plug of each GBIC type that
you ordered. Therefore you will be able to test the GBICs one at a time.). A
failure indicates one or more bad GBICs or their associated connectors and blinks
the Heartbeat LED eight times between three-second pauses. The Continuous
Test mode logs the errors but does not stop on failures and does not indicate
which GBICs failed the test. In order to determine which GBIC/s failed, you must
press the Continuous Test Button again, causing the Switch to go back to normal
operate mode. When the Switch goes into normal operate mode it reads its error
log and indicates any GBIC failures by blinking their associated Logged-in
LEDs.
The GBICs/ports whose Logged-in LEDs are not blinking have passed the test
and are all useable.
Switch Bus Test Failure (9 Blinks)
The Switch may be operable. The Switch Bus Test verifies the ability of the
Switch ASICs to communicate to each other via the busses that interconnect the
ASICs. A failure indicates an inability of an ASIC pair to communicate over one
or more busses. The Switch is operable as long as at least one Frame Bus is
operable. However, some normal processing functions such as in-order
delivery may be adversely affected. A failure blinks the Heartbeat LED nine
times between three-second pauses. No port Logged-in LEDs blink.
