Diagnostics
The Silkworm 2100 switch is designed for maintenance-free operation. It contains self-
diagnostic capabilities that provide switch status, operating statistics, and, in the case of a
failure, aid in isolating the problem.
Loopback paths are incorporated into the switch hardware. Internal Fibre Channel port
logic functions and the paths between the interfaces and central memory are verified by an
internal loopback path test within the switch. An external loopback path test that includes
the motherboard and its GBIC modules checks installed fiber cables and port fault
isolation in cross-port configurations.
Diagnostic Tests
Below are the tests available along with the command to initiate each; they are run from
the local telnet port. See Fabric OS, “Chapter 4 - Diagnostics” for detailed information
on commands.
