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 4-5 on page 55. For a complete understanding of all HP-UX hot-plug techniques and concepts, it is
recommended that you refer to Interface Card OL* Support for HP-UX Servers and Workstations, B2355-90804 at
http://docs.hp.com.
CAUTION
Before adding or replacing a PCI-X card, determine if that card is critical to your system's operation. If you
replace a card that is still operating and it is a critical resource to your system, you may cause undesired
system downtime. Read Interface Card OL* Support for HP-UX Servers and Workstations, Critical
Resources, B2355-90804, 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, perform the following steps:
Step 1. If rack mounted, slide the HP Server out from the rack until it stops. See "Accessing a Rack Mounted Server" on
page 141.
Step 2. Remove the top cover from the chassis. See "Removing the Top Cover" on page 147.
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. See Figure 4-16 on page 60.
CAUTION
Step 5. Ensure that the MRL is already open and insert the PCI-X card to be added into the powered down slot. See
Figure 4-17, "Inserting 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.
58
Do not pull up on the MRL of a powered-on, occupied slot or your system 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.
