How to remove and replace a link card 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: 30 minutes

- TASK COMPLEXITY: 2

FIELD ENGINEER INSTRUCTIONS:
- PROBLEM OVERVIEW
How to remove and replace a link card 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. Disconnect the link cable from the defective link card in the I/O boat.

4. Remove the defective link card and carrier from slot 0 in the I/O boat.
   a. Loosen the carrier locking screw on the carrier handle.
   b. Pull the carrier handle out fully.
      CAUTION! – Pulling the carrier handle raises the carrier plate. If the carrier moves forward before the carrier plate is completely raised, the plastic locator bar might be damaged by hitting the lower front edge of the I/O boat.
   c. Pull the carrier out of the carrier slot and place it on an antistatic surface.
   d. Press the locking latch while you push the carrier handle into the closed position.
      This action lowers the carrier plate, giving you more room to move the PCI card into place on the carrier.

5. Remove the defective link card from the carrier.

6. Install the replacement link card in the carrier.

7. Install the carrier in slot 0 of the 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.
      For troubleshooting information, see Appendix D in the Service Manual.
   e. Lock the carrier handle into place with the carrier locking screw located on the top of the handle.

8. Attach the link cable to the link card.
    NOTE – If the External I/O Expansion Unit has two I/O boats, both boats must be connected to the same host server. Do not connect the second boat to a different server. Also, do not connect the second boat to the first boat; a daisy-chain configuration is not allowed.

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

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.

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.

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.

PARTS NOTE:
501-7040 Fibre Link Card
501-7041 Copper Link Card
