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 PROM. 9. Routing table construction; after addresses are assigned, the Unicast routing tables are constructed. 10. Enable normal N_Port operation. Power-On Diagnostics 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 Should the switch fail to complete POST successfully, the green power LED will be 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. Should this condition occur, the switch should be returned for repair. If a serial link is connected to the 2400 switch (and boot prom version 2.1 is installed) on initial power up, the switch type will be printed to the terminal screen, followed by the message Starting RAM test. On completion of the RAM test, the operating system is loaded into CPU memory and the operating environment is then booted. (A RAM test failure will result in the power LED to blink.) If the switch can completely boot the operating system, but other errors are encountered during POST, these errors will be logged in the system error log. A Telnet session or serial link connection to the switch will enable viewing of the error log. NOTE: A switch boot failure indicates the switch must be taken off-line to be either repaired or replaced. 5-4 Dell PowerVault 51F 8-Port Fibre Channel Switch Installation and Troubleshooting Guide

Power-On Diagnostics
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
Should the switch fail to complete POST successfully, the green power LED will be
set to blink. This is an indication of a fault in one of the initial stages of POST and indi-
cates that the microprocessor is not able to bring up the operating environment.
Should this condition occur, the switch should be returned for repair.
If a serial link is connected to the 2400 switch (and boot prom version 2.1 is installed)
on initial power up, the switch type will be printed to the terminal screen, followed by
the message
Starting RAM test
. On completion of the RAM test, the operating
system is loaded into CPU memory and the operating environment is then booted. (A
RAM test failure will result in the power LED to blink.)
If the switch can completely boot the operating system, but other errors are encoun-
tered during POST, these errors will be logged in the system error log. A Telnet
session or serial link connection to the switch will enable viewing of the error log.
NOTE: A switch boot failure indicates the switch must be taken off-line to be either
repaired or replaced.
