2.6 MODULE
INSTALLATION
XYCOM XVME modules are designed to comply with all physical and electrical
VMEbus backplane specifications.
The XVME-200 DIO Module is a single-high,
single-wide VMEbus module, and as such, only requires the Pl backplane.
The
XVME-290/l DIO Module uses the P2 of the VMEbus backplane, or through the two
50 pin connectors (JKl and JK2) mounted in the P2 area (XVME-290/2). In the
XVME-290/l version, P2 carries all the signals for both PI/T #I and PI/T #2, while
the XVME-290/2 version, JKl carries the signals for PI/T #l and JK2 carries the
signals for PI/T #2.
CAUTION
Never attempt to install or remove any boards before
turning off the power to the bus, and all related external
power supplies.
Prior to installing a module, you should determine and
verify
all relevant jumper configurations, and all
connections to external devices or power supplies. (Please
check the jumper configuration against the diagrams and
lists in this manual.)
To install a board in the cardcage, perform the following steps:
1)
Make certain that the particular cardcage slot which you are going to use
is clear and accessable.
2)
Center the board on the plastic guides in the slot so that the handle on
the front panel is towards the bottom of the cardcage.
3)
Push the card slowly toward the rear of the chassis until the connectors
engage (the card should slide freely in the plastic guides).
4)
Apply straight-forward pressure to the handle located on the front panel
of the module until the connector is fully engaged and properly seated.
NOTE
It should not be necessary to use excessive pressure or
force to engage the connectors. If the board does not
properly connect with the backplane, remove the module
and inspect all connectors and guide slots for possible
damage or obstructions.
