Note
National Instruments has tested and verified that the SO-DIMMs we sell work
with the VXIpc 870 Series. We recommend you purchase your SO-DIMM modules from
National Instruments. Other off-the-shelf SO-DIMM modules are not guaranteed to work
properly.
Changing the Main Power Fuse
The VXIpc 870 Series is equipped with a user-replaceable fuse on the
main power, +5 V from the VXIbus. All other voltages are fused with a
resettable-style circuit breaker. The resettable-style circuit breakers do not
require user intervention. When a short circuit condition is removed, they
automatically reset themselves.
The main power, +5 V, is too high of a current for resettable fuse
technology, so your kit includes a replaceable fuse of type
3AG
, 15A,
Slowblow.
You can replace this fuse without having to remove the cover. The fuse is
accessible through the rear of the unit as shown in Figure 3-12.
