I/O Upgrade
HP-HSC Upgrade
Primary Expansion I/O Upgrade Procedures
To accomplish the upgrade, perform the following steps. Be sure to observe all ESD precautions.
1. Log Off all users and stop all active applications that may be running.
2. Perform a system backup of the entire Operating System and data base. If this is not feasible, perform a backup
of the data base. (Backups should be performed at a scheduled interval as common practice for protecting any
new data or changes to the existing data base.)
3. Perform a system shutdown. Enter "/etc/shutdown -h" at the prompt.
4. Turn the computer key switch to the STANDBY position.
5. At the rear of the computer, unplug the power cord.
6. Remove the cover plate on the primary HP-HSC Expansion I/O slot (next to the Core I/O card) by loosening the
two (one top and one bottom) captive mounting screws and pulling the cover plate away.
7. K450/K460 only: Loosen the six (three top and three bottom) captive screws on the power supply, then grasp
the extractor levers and pull them out.
NOTE
On HP9000/K250/K260/K450/K460 and 979KS systems, the power supply has six
captive screws, three each on the top and bottom.
8. K450/K460 only: Grasp the handle on the power supply and pull it out of the computer.
CAUTION
The power supply may weigh as much as 26.5 lbs (12 kg). Be careful lifting it and be
careful where you put it down.
9. K3x0/K5x0 Only: Remove the adjoining Secondary HSC expansion slot cover by loosening the two (one top
and one bottom) captive mounting screws and pulling the cover plate away.
10. K4x0 only: Remove the adjoining processor slot cover plate by loosening the two (one top and one bottom)
captive mounting screws and pulling the cover plate away (This is necessary to gain access to the system
board.). Remove any processors that are present.
11. Reach into the computer cabinet and remove the plastic dust cover from the HP-HSC expansion connector on
the system board.
12. Remove the plastic dust cover from the HP-HSC expansion card connector.
NOTE
At this point you must determine which HP-HSC cards are going to be added to the
computer. If a graphics card is in the Core I/O card, it needs to be moved to the HP-HSC
expansion card. See “Moving HP-HSC Cards” on page 11 for those procedures.
13. Align the HP-HSC expansion card (HP-HSC cards and components to the left side and the extractor levers out)
into the card slot (1) and slide it into the computer. See Figure 1-4 and Figure 1-5.
