Chapter 5 Installing Additional Boards

NOTE The HP NetServer E 800 may use the HP TopTools software,
but it does not support the HP TopTools Remote Control board
and does not have an I
2 C connector on the system board. For
more information on the use of the HP TopTools function,
refer to Chapter 8, "Configuring the HP NetServer" and
Chapter 9, "HP NetServer Online Documentation CD-ROM."
Accessory Board Installation Guidelines
The following sections provide the guidelines necessary to install the PCI
accessory boards into the NetServer.
NOTE Some full-length PCI boards may need a plastic "handle"
(board extension) on one end to stabilize the board in the
NetServer. If the board requires one and it is not installed, you
may need to install the handle on the board, before installing it
in the HP NetServer.
IRQ Settings
The IRQ settings are automatically assigned and don’t require user intervention.
The HP NetServer uses the Plug-and-Play feature of the PCI boards to correctly
assign its resources automatically.
Using the Primary or Secondary PCI Bus
To support seven PCI accessory slots in the NetServer, the NetServer E 800
has a Primary and Secondary PCI bus. The two busses are pear-to-pear, which
provides approximately equal performance, except when using the two 64-bit slots
versus the 32-bit slots. See Table 5-1.
