Hot-Plug Operation Procedures

The hot-plug procedures described in this section will use the hardware interface only. Software interface
procedures are described in Table 4-7, "Hot-Plug Hardware and Software Interfaces and OS Availability." For
a complete understanding of all HP-UX 11i v2 hot-plug techniques and concepts, it is recommended that you
see the Interface Card OL* Support for HP-UX Servers and Workstations on the HP website at:
http://docs.hp.com.
Before adding or replacing a PCI-X card, determine if that card is critical to your servers

operation. If you replace a card that is still operating and it is a critical resource to your server,
you may cause undesired server downtime. Read Interface Card OL* Support for HP-UX
Servers and Workstations, Critical Resources at http://docs.hp.com, prior to performing a
hot-plug operation.
Online Addition-(OL-A)
Before installing a PCI-X card, ensure that the proper drivers for that PCI-X card are installed.
To add a PCI-X card into an empty slot, follow these steps:
Step 1. If rack mounted, slide the HP server out from the rack until it stops. See "Extending the Server
from the Rack" on page 39.
Step 2. Remove the top cover from the chassis. See "Removing the Top Cover" on page 43.
Step 3. If the power LED is steady-on (power to slot is on), go to step 4. If the power LED is steady-off
(power to slot is off), go to step 5.
Step 4. To turn off power to the slot, pull up on the manual retention latch (MRL) located on the OLX
divider. The power LED goes to steady-off. Figure 4-26 shows the layout of the card divider.
CAUTION
Step 5. Ensure that the MRL is already open and insert the PCI-X card to be added into the powered down
slot. Figure 4-27 shows how to correctly install a PCI-X card.
CAUTION
Step 6. Push the manual retention latch down until it seats against the chassis wall.
Step 7. Turn the PCI-X card lock to the closed position to capture the PCI-X card and manual retention
latch into the closed position.
Step 8. Press the attention button and the power LED starts to blink. Wait until the power LED goes from
blinking to steady-on.
Chapter 4
Do not pull up on the MRL of a powered-on, occupied slot or your server will crash.
This OL-A procedure is for powering down a powered-on, unoccupied slot only. For a
detailed procedure on how to power down an occupied slot see "Online
Replacement-(OL-R)" or "Online Deletion (OL-D)".
When inserting the PCI-X card, be careful you do not accidentally touch an attention
button on the other OLX dividers—this will initiate an undesired shutdown of
another PCI-X card/slot.
Also, ensure that you fully seat the card into the slot or undesired results may occur
after power is re-applied to the slot.
