Boot
Boot occurs after POST is complete and includes the following tasks:
• Performing universal port configuration.
• Initializing links.
• Analyzing the fabric.
If any ports are connected to other switches, the switch participates in a fabric configuration.
• Obtaining a domain ID and assigning port addresses.
• Constructing unicast routing tables.
• Enabling normal port operation.
Switch maintenance
The switch supports only Hewlett Packard Enterprise-branded 8 Gb/s and 16 Gb/s SFP+ optical
transceivers. For the FC connections, the switch uses SFP+ transceivers that support any combination of
SWL, LWL, and ELWL optical media.
If you use an unqualified transceiver, the
switchshow
command output shows the port in a
Mod_Inv
state. Fabric OS also logs the issue in the system error log.
For information about installing transceivers, see
Diagnostic tests
In addition to POST, Fabric OS includes diagnostic tests to help you troubleshoot the hardware and
firmware. This includes tests of internal connections and circuitry, fixed media, and transceivers and
cables.
The tests are implemented by command through a Telnet session or a console set up to the serial
connection to the switch. Some tests require that ports be connected by external cables in order to verify
the serializer/deserializer interface, transceiver, and cable. Some tests require loopback plugs.
Diagnostic tests run at a link speed of 2, 4, 8, 10, or 16 Gb/s (FC), depending on the speed of the link
being tested and the type of port.
NOTE:
• Diagnostic tests can temporarily lock the transmit and receive speed of the links.
• Hewlett Packard Enterprise does not support 2 Gb/s connectivity to the StoreFabric SN4000B,
SN6500B, SN6000B, and SN3000B 16Gb FC switches.
For information about specific diagnostic tests, see the Fabric OS Troubleshooting and Diagnostics
Guide.
Switch management
You can use the management functions built into the switch to monitor the fabric topology, port status,
physical status, and other information to help you analyze switch performance and to accelerate system
debugging.
For information about upgrading the Fabric OS version installed on your switch, see the Fabric OS
Administrator’s Guide.
You can manage the switch using any of the management tools listed in
more information on the CLI commands, see the Fabric OS 7.3.x Command Reference Manual.
