Installation Instructions
The following sections discuss the installation of the MVME166 in a VME
chassis, and describe system considerations relevant to the installation.
Ensure that an EPROM device is installed as needed. The factory
configuration provides for one EPROM (installed for 166BBug, the BootBug
firmware subset of the MVME166Bug debug monitor contained in Flash
memory) in socket U12. Ensure that all header jumpers are configured as
desired.
MVME166 Module Installation

WARNING
DANGEROUS VOLTAGES, CAPABLE OF CAUSING
DEATH, ARE PRESENT IN THIS EQUIPMENT. USE
EXTREME CAUTION WHEN HANDLING, TESTING,
AND ADJUSTING.
b. Remove chassis cover as instructed in the equipment user’s manual.
c. Remove the filler panel(s) from the appropriate card slot(s) at the front and
(if the chassis has a rear card cage that you intend to use) rear of the
chassis.
The MVME166 module requires power from both P1 and P2. It may be
installed in any double-height unused card slot, if it is not configured as
system controller. If the MVME166 is configured as system controller, it
must be installed in the leftmost card slot (slot 1) to correctly initiate the
bus-grant daisy-chain and to have proper operation of the IACK-daisy-
chain driver.
