SANbox-8 Fibre Channel Switch
Installer’s/User’s Manual 59008-03 Rev. A Diagnostics/Troubleshooting 3-7
5. After a few seconds of testing, if the Heartbeat LED is blinking the
normal “heartbeat” (about once per second), the GBIC passes the test.
If the Heartbeat LED blinks the 8-blink error code, the GBIC failed.
Repeat steps 2 through 5 to test all GBICs one at a time.
6. When all tests are complete, place the Test Mode Switch back in the
“Normal Run” position (small dot on the end of the shaft pointing
straight up).
7. Cycle the chassis power to cause a reset.
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.
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.
