Electrostatic Discharge
To avoid catastrophic or hidden damage to components,
wear a wrist strap and use a static-dissipative work surface
connected to the chassis when handling components. Use
an antistatic service kit, such as 3M 8501/8502/8505 or
equivalent.

Technical Reference Card
Resource Sharing
Interrupt A: Slot 2 and Slot 6
Interrupt B:
Interrupt C: Slot 1 and Slot 4
Slot 5 does not share any interrupts
HP recommends for most environments to let the
server assign resources and PCI interrupts. The LC 3
is capable of avoiding interrupt conflicts through
interrupt sharing.
However, when two similar or dissimilar PCI Cards
continue to have conflicts, it is possible to manually
assign interrupts through the BIOS Setup Utility.
The following slots share interrupts:

which may fit but will not function correctly
DIMMs can be installed in any order in any
of the four DIMM sockets
Use only HP DIMMs listed on this label at far right
DIMMs can be 64MB, 128MB, or 256MB in
