9. Push the server all the way back into the rack until it stops. See “Inserting the Server into
the Rack” (page 32).
Online Replacement (OL-R)
As discussed earlier, OL-R is a combination of an OL-D procedure followed by an OL-A procedure.
CAUTION: For HP-UX 11i v2 only. You can only replace an existing card with a like card.
To remove and replace a PCI-X card into a populated slot, follow these steps:
1. If rack mounted, slide the HP server out from the rack until it stops. See “Extending the
Server From the Rack” (page 31).
2. Remove the top cover from the chassis. See “Removing the Top Cover” (page 36).
3. Press the attention button located on the OLX divider that controls the affected slot. The
power LED starts to blink. Wait until the power LED goes from blinking to steady-off.
NOTE: After pushing the attention button, you have five seconds to cancel the operation
by pushing the attention button again.
4. Turn the PCI-X card lock on the chassis until the manual retention latch (MRL) is free to
pull up.
5. At this point, the power to the slot is off; pull up on the manual retention latch located on
the OLX divider. Figure 4-26 shows the layout of the PCI-X card divider.
6. Remove the existing PCI-X card from the slot.
7. Insert the new PCI-X card into the powered off slot. Figure 4-27 shows how to correctly
install a PCI-X card.
CAUTION: When inserting the PCI-X card, be careful you do not accidentally touch an
attention button on the other OLX dividers. This initiates an undesired shutdown of another
PCI-X card/slot. If you accidentally press the wrong attention button, you have five seconds
to push the attention button again to cancel the action.
Also, ensure that you fully seat the card into the slot or undesired results may occur after
power is reapplied to the slot.
8. Push the manual retention latch down until it seats against the chassis wall.
9. Turn the PCI-X card lock on the chassis to the closed position. This locks the PCI-X card into
its slot and the manual retention latch into the closed position.
10. Press the attention button. The power LED starts to blink.
11. Wait for the power LED to stop blinking. The PCI-X card is now active.
12. Replace the top cover. “Replacing the Top Cover” (page 36).
13. Push the HP server all the way back into the rack until it stops. See “Inserting the Server
into the Rack” (page 32).
Removing and Replacing OLX Dividers
OLX dividers are located on the I/O baseboard, between the PCI cards. Six OLX dividers provide
short circuit protection to the hot-plug PCI accessory boards by preventing inadvertent contact
between boards during the replacement or addition of a board.
