2-6 StorageWorks Fibre Channel Storage Switch Sevice Guide
Initialization Steps
At power-on or reset, the following steps are initiated:
1. Bootrom Memory Test.
2. Switch operating system initialization.
3. Hardware initialization, including resets, internal addresses assigned to
G_Port and FL_Port ASICs, serial port initialized, front panel initialized
4. Full POST is performed.
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.
This completes the initialization sequence
Power-On Diagnostics
When an error is detected during POST, it may be written to the system error
log and is available for analysis through Telnet.
When an error disables the Switch from completing the boot process – a fatal
error – an error is displayed on the front panel.
If the error occurred in the POST processing, before the Switch is able to
display the boot failure, causes the Switch’s front panel power on indicator
flashes (instead of its normal steady light) indicating the Switch failed the boot
process and is not operating. Refer to the User’s Guide for more information.
NOTE:
A Switch boot failure indicates the Switch must be taken offline to be repaired or
replaced. Contact your service representative.
