44 Sun Fire V890 Server Owner’s Guide • May 2004
Note – In the unlikely event that the system controller card fails while the system
console is directed to RSC, the system console will be unavailable. To recover from
this situation, press the system Power button to initiate a graceful software
shutdown. Then turn the keyswitch to the Diagnostics position or use the OpenBoot
emergency procedure for resetting ID PROM configuration variables to their default
values. See “About OpenBoot Emergency Procedures” on page 119. These measures
will temporarily redirect the system console to the factory default device. If you are
not installing a replacement system controller card right away, you may want to
restore the local system console until a replacement card is available. See “How to
Restore the Local System Console” on page 45.
Caution – All internal options (except disk drives and power supplies) must be
installed only by qualified service personnel. Installation procedures for these
components are covered in the Sun Fire V890 Server Service Manual, which is
included on the Sun Fire V890 Documentation CD.
