Appendix D System Board Jumper Settings D-3
JP15 1-2 (Open) This jumper is for use by Sun service engineers only. It enables
and disables emergency recovery of the LOM firmware. In its
default state (Open), recovery of the firmware is not possible.
However, service engineers might need to follow a special
procedure to recover the firmware for the LOM, and this
procedure involves temporarily changing the setting of JP15 to
Fitted. Afterwards, it must always be returned to Open.
JP16 1-2 (Fitted) This jumper write-enables the OBP software to allow you to
update it. If you need to protect the OBP software from being
over-written, change the jumper setting to Open.
JP17 1-2 (Open) This jumper tells the DVD or CD-ROM drive (if one is installed)
that it is a Master ATA device. For the DVD and CD-ROM
drives currently available for the Sun Fire V120 and Netra 120
systems, this jumper must be Open.
