Power-On-Self-Test (POST)
For example:
•A PROM checksum failure is an example of a fatal error. This indicates that the PROM firmware is corrupt and the Switch may not run.
•A failure associated with a Fibre Channel port is an example of a non-fatal error. The Switch can isolate the bad port and operate with the remaining ports.
Note:
Whether the problem is fatal or non-fatal, please contact Ancor Customer Service. If the problem is non-fatal, it may allow you to run in a degraded mode until the problem is fixed.
When POST is complete and errors are encountered, the Switch uses the Heartbeat LED to blink an error code which describes the first error encountered. These error codes are described next in this section. The Switch then reads its error log and if it has encountered non-fatal errors that affect one or more ports (but the remaining ports are operable) it will disable the bad ports and blink the Logged-in LED of the affected port or ports to indicate which ports are down. If the error is non-fatal but does not affect a single port or group of ports, only the Heartbeat LED blinks an error code. In all cases, the Switch displays the POST error indications until you power it down.
For example:
•If the POST encounters a PROM Checksum error the entire Switch is inoperable. The Heartbeat LED will blink the error code for the fatal PROM Checksum error. The entire Switch is down and no port Logged-in LEDs are lit because the problem does not affect an individual port or ports.
•If the POST encounters a Bus error, the Switch may operate in a degraded mode because it has multiple Buses. It can operate with one or more of them in operation but some normal processing functions such as in-order delivery may be adversely affected. The Heartbeat will blink the error code for the non-fatal Bus error. The Switch may operate (a little slower) and no port Logged-in LEDs are lit because the problem does not affect an individual port or ports.
•If the POST encounters an Auto-Connect error, the Switch may operate in a degraded mode because the Auto-Connect tests the ability of ports to accomplish an Auto-Connect and ports that pass this test can still operate. The Heartbeat will blink the error code for the non-fatal Auto-Connect error. The Switch disables both ports that could not accomplish an Auto- Connect and blinks their Logged-in LEDs to indicate that these ports are down.
