1. Preliminary POST diagnostics.
2. VxWorks operating system initialization.
3. Hardware initialization (resets, internal addresses assigned to G_Port and FL_Port ASICs, serial port
initialized, front panel initialized).
4. Full POST.
5. Link initialization; receiver/transmitter negotiation to bring connected ports online.
6. Fabric analysis; the switch checks for ports connected to other Fabric elements. If there are other
Fabric elements connected, it identifies the master switch.
7. 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.
8. Routing table construction; after addresses are assigned, the unicast routing tables are constructed.
9. Enable normal N_Port operation.
Power-on Diagnostics
If a malfunction is discovered during the POST process, it is written to the system error log and is available
for analysis via a Telnet session. (See "
diagShow " and " errShow " for details.)
If the malfunction prohibits the switch from completing the boot process (fatal error), the switch stops the
boot process.
NOTE: A switch boot failure indicates the switch must be taken offline to be either repaired or replaced.
