24 omdiag: Using the Diagnostic Service
– S-Registers Test — Uses the selected range of S-Registers to exercise and diagnose the
functionality of the modem. The test saves the current S-register values, sets a new value, verifies
that the new value can be read and is correct, and restores the original value. The result codes are
verified and displayed either textually or numerically.
NOTE: In cases where the Windows registry with modem drivers is corrupted due to bad installs/uninstalls,
the modem diagnostic might give unexpected results.
• Broadcom Modem Test — Used for both external (for example, connected to a serial port) and internal
modems (for example, connected to a PCI slot).
The Broadcom Modem test performs the following tests:
NOTE: The following tests are not supported on systems running a Red Hat Enterprise Linux
operating system.
– Broadcom Modem Dialtone Detection Test — Verifies the correct operation of the codec, DAA,
and control logic on the Broadcom V.92 56K modem. This is accomplished by detecting the
presence of a dial tone on the telephone line. A telephone line must be attached to the modem for
this test to pass. If a dialtone is not detected, a warning is reported.
– Broadcom Modem Loopback Test — Instructs the Broadcom V.92 56K modem to perform a
standard local analog loopback test. A test pattern is looped back and checked by the modem. The
test fails if the modem reports any errors during the test.
– Broadcom Modem AT Command Test — Verifies the correct operation of the AT command
microprocessor and associated control functions on the Broadcom V.92 56K modem. A series of AT
commands are issued and the responses are checked for correctness. Each command must
correctly return "OK" or an error is reported.
omdiag chassis network
Use the omdiag chassis network command to test the NIC.
• Generic Network Diagnostic Test — The following two tests are available on all
Dell™ supported NICs:
– NIC Communication Test — Checks whether the NIC under test is physically connected (wired)
to the network. It also checks whether the NIC has a valid IP address.
NOTE: The network team test is only available on systems running a supported Microsoft Windows
operating system.
– NIC Team Test — Checks whether the NIC under test is in team mode. NIC teaming is one
method for providing high availability and fault tolerance in systems.
The following test runs on the Broadcom NIC:
NOTE: The following Broadcom NIC tests are not supported on systems running a Red Hat Enterprise Linux 4 (for
Intel
®
x86 and Intel EM64T) operating system.
• Broadcom Network Diagnostic Test — Analyzes overall controller health by checking for I/O conflicts,
memory faults, EEPROM operability, and transmit and receive functionality.
