5V and 3.3V PCI boards are keyed such that it is not possible
to insert them into the wrong voltage slots. Universal boards
are keyed such that they can be placed in any slot.
Refer to the HP NetServer LXr 8500 Installation Guide for
more complete information on adding accessory boards.
Install Accessory Boards in the I/O Baseboard
5. Install each accessory board in the I/O tray as follows:
a. Release the PCI hold-down latch to open the slot. (See Figure 7-1.)
The PCI hold-down latch is used to keep the PCI boards in place and to
activate the PCI LED display. The PCI LED display indicates if power
is applied to the individual slot, or if the slot has a problem, such as a
cable is disconnected from the board.
5a. Press the center of the
PCI hold-down latch to
disengage it. Then swing
it back out of the way.
