Figure 2-1 shows the placement of the switches, PCB jumper headers,
connectors, and LED indicators on the controller. The controller has been
factory tested and is shipped with the factory jumper settings listed in the
following sections. It operates with its required and factory-installed debug
monitor, MVME162Bug (162Bug), with these factory jumper settings.
Settings can be made for:
System controller selection (J1)
General-purpose readable register configuration (J11)
EPROM/Flash configuration (J12)
SRAM backup power source selection (for onboard SRAM: J13 on
the MVME162LX PCB; for the SRAM mezzanine: J1 on the
SRAM mezzanine)
SCSI bus termination (J14)
The MVME162LX Embedded Controller is factory-configured as a
VMEbus system controller (a jumper is installed across pins 1 and 2 of
PCB header J1). Remove the J1 jumper if the controller is not to act as the
system controller. Note that when the MVME162LX is functioning as a
system controller, the

For controllers without the optional VMEbus interface (with
no VMEchip2), the jumper may be installed or removed
without affecting normal operation.
