Replacing the MVME167-34 single board computer card
Use this procedure to replace the MVME167-34 card. Figure 3-14 shows
the side view of this card.
1
Shut down the NAC 2 software.
Refer to NAC 2 System Administration and Maintenance Guide (NTP
553-4011 - 510), "Maintenance and Administration programs: system
running" chapter, "Shut down the system" section for instructions on
shutting down your NAC 2 system.
Refer to NAC 2 System Administration and Maintenance Guide (NTP
553-4011 - 510), "Maintenance and Administration programs: system
shut down" chapter, "Restart and Power Down System Utilities" section
for instructions to enable the System Restart feature.
2
Power down the application module (AM). The circuit breaker (CB) is
located at the left of the AEM.
3
Remove the front and rear covers of the pedestal column located at the
base of the column.
Remove the two screws located at the upper left and right hand corners
of the pedestal cover.
4
Locate the existing MVME167-34 single board computer card that
needs to be replaced. Use a Phillips screwdriver to remove the top and
bottom retaining screws which keep the card in place. Press up on the
card's top release lever while pressing down on the bottom card release
lever. When enough pressure is applied, the card pushes itself out
about a quarter of an inch. Carefully pull the card out of the slot and set
it aside.
5
Take the MVME167-34 replacement card from its packaging. Since
jumpers are set and tested in the factory, it is not necessary to change
the jumper settings on the cards.
6
Carefully align the card with the black plastic guides found along the top
and bottom of the VME card cage. Keeping the card level, slide it into
the card cage until the card is flush with the faceplate of the AM.
If you are uncertain as to whether the card is in as far as it will go,
simultaneously press up on the top latch and down on the bottom latch.
If the card pops forward slightly, then the card was in as far as it could
go.
7
Once the card is inserted into the card cage, use a screwdriver to
tighten the top and bottom retaining screws to keep the card in place.
Tightening the screws while the card is not fully inserted could result in
stripping the screws.
