Lan Boot Error Messages - HP 400 Series Servicing Manual

If a failure is detected in the power-up test, the following failure message is displayed:
HP98643 (LAN) at 21, 080009000001 Failed
This message shows that one of the internal tests on the interface failed. The tests in-
clude register operations, shared ram, non-volatile ram checksum and several different
internal loopback tests.
If extended testing is selected from the Test Menu, the LAN interface is subject to both
the normal testing and the external loopback tests. LAN error messages (see Table 4-5)
may be displayed below the LAN identification message.
If no servers respond to the Boot ROM's attempts to initiate a boot session, then the
user sees no other indication of LAN activity. For each server that responds, the
display shows the following :LAN, followed by the select code, followed by either the
servers name or its Link Address. Under this will appear the list of systems provided by
that server as shown in the following example:
:LAN, 21, 080009000008
