7. Fabric analysis; the switch checks for ports connected to other fabric elements. If there are other fabric elements connected, it identifies the master switch. 8. Address assignment; after the master switch is identified, port addresses may be assigned. Each switch tries to keep the same addresses that were previously used. These are stored in the switch's configuration flash programmable readonly memory (PROM). 9. Routing table construction; after addresses are assigned, the Unicast routing tables are constructed. 10. Enable normal N_Port operation. When powering-on a switch, the switch conducts a series of diagnostic tests on the following system functions: Dynamic RAM Port register Central memory CMI connector CAM Port loop back If the switch fails to complete POST successfully, the green power LED is set to blink. This is an indication of a fault in one of the initial stages of POST and indicates that the microprocessor is not able to bring up the operating environment. If this condition occurs, the switch should be returned for repair. If the switch can completely boot the operating system, but other errors are encountered during POST, these errors are logged in the system error log. A Telnet session or serial link connection to the switch enables viewing of the error log. NOTE: A switch boot failure indicates the switch must be taken off-line to be either repaired or replaced. The following tests are available from the switch's front panel and by way of Telnet. For details on how to use the switch's front panel buttons and how to access the Test Menu from the front panel, see "Managing Through Front Panel Buttons," found in Chapter 3. NOTE: Accessing the switch by way of Telnet provides a more detailed response indicating the switch's condition and allows the use of some commands which do not have an equivalent front panel command. 5-4 Installation and Troubleshooting Guide

When powering-on a switch, the switch conducts a series of diagnostic tests on the
following system functions:
¿
Dynamic RAM
¿
Port register
¿
Central memory
¿
CMI connector
¿
CAM
¿
Port loop back
If the switch fails to complete POST successfully, the green power LED is set to blink.
This is an indication of a fault in one of the initial stages of POST and indicates that the
microprocessor is not able to bring up the operating environment. If this condition
occurs, the switch should be returned for repair.
If the switch can completely boot the operating system, but other errors are encoun-
tered during POST, these errors are logged in the system error log. A Telnet session or
serial link connection to the switch enables viewing of the error log.
NOTE: A switch boot failure indicates the switch must be taken off-line to be either

Menu from the front panel, see

NOTE: Accessing the switch by way of Telnet provides a more detailed response indi-
cating the switch
