Removal and Replacement Procedures 2-71 I/O Expansion Boards This removal and replacement section is for standard I/O expansion boards that are available as options. The board pictured in Figure 2-62 is an Extended SCSI type I/O expansion board. To remove an I/O expansion board: 1. Unlock and open the PCI Hot Plug access door. See "I/O Expansion Slots" earlier in this chapter. 2. Use the PCI Hot Plug button or software application to turn off power to the slot. The green LED flashes during the power down transition and turns off when system shutdown is complete. For more information refer, to the Compaq ProLiant 8000 Servers Setup and Installation Guide. CAUTION: DO NOT open the slot release lever unless the green PCI Hot Plug LED power indicator for the slot is off. If the lever is opened before power to the slot is turned off, system power down and subsequent data loss could occur. For more information on the power LEDs, refer to Chapter 4, "Connectors, Switches, and Status Indicators." 3. When the green LED for the slot is off, disconnect the cables to the selected PCI expansion board. 4. Push the tab on the slot release lever , then swing the slot release lever back to unlock the expansion board. 5. Slide the slot keeper to the open position if the expansion board is full length . 6. Disconnect any cables plugged into the selected expansion board. 7. Lift the expansion board through the top of the server . 1 3 2 4 Figure 2-62. Removing an I/O expansion board Reverse steps 1 through 7 to replace the I/O expansion board. IMPORTANT: Installing a 33-MHz expansion board into a 66-MHz slot will cause the adjoining expansion slot to run at 33-MHz even if it is populated by a 66-MHz expansion board. Both populated slots will run at the slower 33-MHz rate.

Removal and Replacement Procedures
2-71
I/O Expansion Boards
This removal and replacement section is for standard I/O expansion boards that are available as
options. The board pictured in Figure 2-62 is an Extended SCSI type I/O expansion board.
To remove an I/O expansion board:
1.
Unlock and open the PCI Hot Plug access door. See
“
I/O Expansion Slots
”
earlier in this
chapter.
2.
Use the PCI Hot Plug button or software application to turn off power to the slot. The green LED
flashes during the power down transition and turns off when system shutdown is complete. For
more information refer, to the
Compaq ProLiant 8000 Servers Setup and Installation Guide
.
CAUTION:
DO NOT open the slot release lever unless the green PCI Hot Plug LED power
indicator for the slot is off. If the lever is opened before power to the slot is turned off, system
power down and subsequent data loss could occur. For more information on the power LEDs,
refer to Chapter 4,
“
Connectors, Switches, and Status Indicators.
”
3.
When the green LED for the slot is off, disconnect the cables to the selected PCI
expansion board.
4.
Push the tab on the slot release lever
, then swing the slot release lever back
to unlock
the expansion board.
5.
Slide the slot keeper to the open position if the expansion board is full length
.
6.
Disconnect any cables plugged into the selected expansion board.
7.
Lift the expansion board through the top of the server
.

Removing an I/O expansion board
Reverse steps 1 through 7 to replace the I/O expansion board.
IMPORTANT:
Installing a 33-MHz expansion board into a 66-MHz slot will cause the adjoining expansion
slot to run at 33-MHz even if it is populated by a 66-MHz expansion board. Both populated slots will run
at the slower 33-MHz rate.
