Power-On-Self-Test (POST)

Overview

The Switch checks the state of the Test Mode switch as part of its power-up proce- dure. Refer to Figure 3-3for the location of the Test Mode switch.

Figure 3-1 Test Mode Switch

The normal setting of this switch (note the location of the dot on the switch relative to the dot on the faceplate) instructs the Switch to run the diagnostics one time at startup. If no fatal errors are encountered, the Switch places itself in normal operating mode. The diagnostics run at startup are the Power-On-Self-Test (POST) diagnostics.

These POST diagnostics check for proper Switch operation except for the GBICs. During the POST, the Switch logs any errors encountered. Some POST errors are fatal, others are non-fatal. A fatal error disables the switch so that it will not operate. A non-fatal error allows the switch to operate, but with some decrease in performance until the problem can be corrected.

For example:

•A PROM checksum failure is an example of a fatal error. This indicates that the PROM ﬁrmware is corrupt and the Switch will not operate.

•A failure associated with a Fibre Channel port is an example of a non-fatal error. The Switch can isolate the bad port, while the other ports continue to operate.
