The password override jumper (J20) will allow you to override a misplaced or forgotten BIOS
password. Connecting the pins together with a jumper and starting the system will activate this
jumper.

The Whitebox / Appliance jumper (J16) provides a selection between “Whitebox” mode and
“Appliance” mode for the server. Whitebox mode is the normal mode of operation for the server
and is in effect when no jumper is covering the pins of the jumper header. When a jumper is
placed on this jumper header “Appliance” mode is initiated.
Appliance mode activates the following:
1)
Watchdog timer is activated on the system
– The Watchdog timer is a chronometer on
the baseboard that is activated when the “Appliance” mode jumper is put in place at J16. It
serves to reset the system in the event of a software failure or crash. To do this, the timer
works in conjuction with the Advanced Server Management (ASM) software version 1.3
which can be loaded onto any of the approved operating systems of the SRMK2. The
Watchdog timer “pings” the ASM software at pre-set intervals and waits for a response. If
the software does not respond within a specified period of time the Watchdog timer reboots
the system and logs the error. See the section entitled “WatchDog Timer” under the
Advanced Server Management section for more details on how to set the timer services
through ASM.
2)
Emergency Console Redirection is activated
– If the SRMK2 server has the
Whitebox/Appliance jumper set to “Appliance” mode (Eg: The jumper is in place at site J16
on the motherboard) and the Watchdog Timer fires several times in a row (indicating a critical
system failure), the SRMK2 system will then enter Emergency Console Redirection mode.
This is a text-based diagnostic mode in which the screen console and keyboard/mouse activity
are redirected through the serial port to another computer via a null modem cable. The
“Client” computer here can issue commands to the SRMK2 machine via a hyperterminal
program. For further instructions on what commands may be given, see Appendix A.
