How to remove and replace a PCI-X/PCI Express I/O Boat in an External I/O Expansion Unit

Solution

DISPATCH INSTRUCTIONS
- WHAT SKILLS DOES THE ENGINEER NEED:
Engineer has to complete the host system's (Mx000/T5xxx) training.

- TIME ESTIMATE:
60 minutes

- TASK COMPLEXITY:
2 = high complexity product process knowledgeable resource required

FIELD ENGINEER INSTRUCTIONS:
- PROBLEM OVERVIEW
How to remove and replace a PCI-X/PCI Express I/O Boat in an External I/O Expansion Unit

- WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE
RESOLUTION ACTIVITY?
For Mx000 systems the link must be powered down if the domain is up and running.
    Power down the link by disconnecting the server IOU slot:
    # cfgadm -c disconnect ap_id
     Where ap_id is the server IOU slot that contains a link card.

For T5xxx systems or a cold replacement on Mx0000 stop the domain that is connected to the I/O boat.
    For information about stopping a domain, refer to the documentation for the server.

For T5xxx systems turn off the AC switches on both PSUs at the front of the External I/O Expansion Unit.

- WHAT ACTION DOES THE ENGINEER NEED TO TAKE:
1. Use an antistatic strap for this procedure.

2. Move the cable plate to the service position:
   a. Loosen the cable plate locking screw(s).
   b. Pull the cable plate toward you approximately 0.5 in./13 mm, then raise it approximately 0.75 in./20 mm, until the bottom of the plate is above the tops of the support brackets.
   c. Push the cable plate forward to its service position so that the cable plate rests on the support brackets.
   The tabs on the sides of the cable plate should lie in the small notches on the tops of the support brackets.

3. Label all I/O cables.

4. Disconnect the link cable from the link card in slot 0 in the defective I/O boat

5. Disconnect the I/O cables from the PCI cards in the defective I/O boat.

6. Loosen the captive screws at the top of the defective I/O boat.

7. Remove the defective I/O boat from the I/O boat slot and set it flat on an antistatic surface.
   When you can see the warning label on the top of the I/O boat, the boat is almost fully out of the boat slot.
   CAUTION! Do not allow the rear of the I/O boat to drop. The connector at the rear of the boat can be damaged if it strikes the edge of the slot.
   Do not rest an I/O boat vertically. The plastic electrical connector on the back is breakable.
   A pivoting flap behind the I/O boat drops down to prevent loss of cooling air.

8. Insert the replacement I/O boat into the I/O boat slot.
    The pivoting flap automatically swings up and out of the way.

9. Lock the I/O boat in place with the two captive screws at the top of the boat.

10. Remove the link card and carrier from slot 0 in the old I/O boat.
    The carrier is labelled Link 0.
    Each carrier is keyed to fit in a specific slot. (The key is an M2 screw located at the top front of the carrier.) A label on the front of the carrier shows the slot number.
    CAUTION! The carrier can be damaged during removal and during insertion.

11. Install the link card and carrier in slot 0 of the new I/O boat:
   a. Pull the carrier handle into the fully open position to raise the carrier plate.
   b. Carefully place the carrier in the card guides at the top and bottom of the carrier slot in the I/O boat.
   c. Press on the metal front panel of the carrier to push the carrier fully into the carrier slot.
      CAUTION! Do not press the plastic carrier handle during Step c. If you press the handle, the PCI card and the sliding carrier plate might suddenly fall, breaking the plastic locator bar by hitting it against the lower edge of the I/O boat.
   d. Push the carrier handle into the closed position.
      This action seats the PCI card in the card socket.
      CAUTION! If the carrier handle does not close easily, the PCI card might not be seating properly in the card socket in the I/O boat. Remove the carrier and inspect the PCI card. If the bottom of the PCI card is not perfectly horizontal, loosen the card locks and realign the card on the carrier.
   e. Lock the carrier handle into place with the carrier locking screw located on the top of the handle.

12. Move PCI cards and carriers from slots 1 through 6 in the old I/O boat to the new I/O boat.
    See Step 10 and Step 11 above for instructions to safely remove and insert carriers.

13. Attach the I/O cables to the PCI cards.

14. Move the cable plate back into the normal position and tighten the cable plate locking screw(s).

15. Connect the link cable between the link card in the host server and the link card in the I/O boat.

OBTAIN CUSTOMER ACCEPTANCE
- WHAT ACTION DOES THE CUSTOMER NEED TO TAKE TO RETURN THE SYSTEM TO
AN OPERATIONAL STATE:
For T5xxx systems turn on the AC switches on both PSUs at the front of the External I/O Expansion Unit.
On the PSUs the AC power and DC power LEDs should light.

For Mx000 systems the link must be powered up again if the domain is up and running.
    After repairing a link, power up the link by typing:
    # cfgadm -c configure ap_id
    Where ap_id is the IOU slot in the host server to which the I/O boat is connected.

For T5xxx systems or a cold replacement on Mx000 start the domain that is connected to the I/O boat.
For information about starting a domain, refer to the documentation for the server.
