Hardware Diagnostic Tests

If you believe that the switch is not operating correctly, you can reset the

switch to test its circuitry and operating code. To reset a switch, either:

Power cycling the switch, pressing the Reset button, and the software reset

or reboot options all cause the switch to perform its power-on self-test, which

almost always will resolve any temporary operational problems. These reset

processes also cause any network traffic counters to be reset to zero and cause

the System Up Time timer to reset to zero. Neither of these reset procedures

causes any changes to the switch configuration.

The self-test passes if the Fault and Self Test LEDs on the front of the switch

go off after approximately 90 to 150 seconds depending on the number and

type of modules installed in the switch. If these LEDs stay on longer than 180

seconds or begin flashing, the switch, or a module, or an individual mini-GBIC

may have to be replaced as indicated by the LEDs.

See "Diagnosing With the LEDs" on

the LED patterns.

Useful diagnostic messages may be displayed on the console screen when the

switch is reset. As described in chapter 2 under step 8, "Connect a Console to

the Switch", connect a PC running a VT-100 terminal emulator program or a

standard VT-100 terminal to the switch's Console Port and configure it to run

at 9600 baud and with the other terminal communication settings shown on

page

displayed.
