MVME177 Module Installation Instructions
When you have configured the MVME177Õs headers and installed
the selected EPROMs in the sockets as described previously, install
the MVME177 module in the system as follows:
1. Turn all equipment power OFF and disconnect the power
cable from the AC power source.
!
Caution
Inserting or removing modules while power is applied
could result in damage to module components.
!
Warning
Dangerous voltages, capable of causing death, are
present in this equipment. Use extreme caution when
handling, testing, and adjusting.
2. Remove chassis cover as instructed in the equipment user's
manual.
3. Remove the filler panel(s) from the appropriate card slot(s) at
the front and rear of the chassis (if the chassis has a rear card
cage). The MVME177 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
MVME177 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. Install the MVME177 in the front of
the chassis. You can install the MVME712x in the front or the
rear of the chassis. Other modules in the system may have to
be moved to allow space for the MVME712M which has a
double-wide front panel.
4. Carefully slide the MVME177 module into the card slot. Be
sure the module is seated properly into the P1 and P2
connectors on the backplane. Do not damage or bend
connector pins. Fasten the module in the chassis with screws
