Removing and replacing a PCI adapter contained in a cassette in an IBM i partition that is powered on

Procedures performed on a PCI adapter in an IBM® i partition that is powered on, also known as hot-plug procedures, require the system administrator to take the PCI adapter offline prior to performing the operation. Before taking an adapter offline, the devices attached to the adapter must be taken offline as well. This action prevents a service representative or user from causing an unexpected outage for system users.

To remove and replace an adapter, do the following steps:

Determine the location of the PCI adapter in the system.
Record the slot number and location of each adapter being removed. Adapter slots are numbered either below or along the side of each adapter slot.
Ensure that any processes or applications that might use the adapter are stopped.
Go to your terminal and type strsst on the command line of the Main Menu and press Enter.
Type your service tools user ID and service tools password on the System Service Tools (SST) Sign On display. Press Enter.
Select Start a service tool from the System Service Tools (SST) display. Press Enter.
Select Hardware service manager from the Start a Service Tool display and press Enter.
Select Packaging hardware resources (system, frames, cards) from the Hardware Service Manager display. Press Enter.
Type 9 (Hardware contained within package) in the System Unit or Expansion Unit field of the unit where you are removing the card, then press Enter.
Select the option to Include empty positions.
Select Concurrent Maintenance on the card position where you want to remove the card and then press Enter.
Select the option to Toggle LED blink off/on. A light-emitting diode (LED) located on your system or I/O enclosure blinks identifying the PCI adapter position you chose. Physically verify that this is the slot where you want to remove the adapter.
Select the option to Toggle LED blink off/on to stop the blinking LED.
Select the option to Power off domain on the Hardware Resource Concurrent Maintenance display and press Enter.
Wait for the Hardware Resource Concurrent Maintenance display to appear with this message: Power off complete
Label, and then disconnect all cables attached to the adapter you plan to remove.
Record the slot number and location of each adapter being removed.
Note: Adapter slots are numbered below or along side of each PCI adapter slot.
Lift up on the PCI adapter EMC shield (A) as shown in Figure 1, and then rotate it up and away from the cassette as shown in Figure 2.

Figure 2. Rotate the EMC shield into the open position
Remove the cassette. Lift up the lower cassette handle (B) as shown in the following figure. Pull the PCI cassette (C) out of the system.
Attention: A cassette containing either a PCI adapter or filler panel must be placed in the PCI adapter slot of the system unit for proper air flow and cooling.

Figure 3. PCI adapter cassette removed from the system unit
Place the cassette with the cover facing up on an approved ESD surface. The cover will have a label on it.
Install the replacement adapter into the PCI adapter cassette by completing the following steps. If the cassette is not going to contain a replacement adapter, use this same procedure to place an adapter filler panel in the cassette.
1. Remove the cassette cover by doing the following steps:
  1. Slide the cover latch (A) to disengage it from the pivot pin (C) as shown in the following figure.
  2. Lift the cover (B) off of the pivot pin.
  3. Slide the cover off of the cassette.
    Figure 4. PCI adapter cassette cover removed
2. Remove the adapter from the cassette by doing the following steps:
  1. Unlock the adapter retainers by rotating the retainer clip (A) into the horizontal position. See Figure 5.
    Notes:
    - The edge of the adapter located at the end of the cassette that contains the cassette handles is called the adapter tailstock.
    - Two retainers are located at the top of the cassette, along the top edge of the adapter. Two more retainers are located at the edge of the cassette opposite of the adapter tailstock.
    - When the retainer clip is in the horizontal position, the adapter retainers are unlocked and can slide away from the card.
    - If the corner support retainer is used, unlock it, and then slide the corner support retainer away from the card.
  2. Push the adapter retainers (B) away from the adapter.
  3. Unlock the adapter tailstock clamp (C).
  4. Rotate the adapter out of the cassette by grasping the edge of the adapter opposite the tailstock, and then firmly rotate the adapter toward the bottom of the cassette.
  5. Lift the adapter out of the tailstock retaining channel.

3. Place the new adapter in the cassette.
  Attention: A cassette containing either a PCI adapter or filler panel must be placed in the PCI adapter slot of the system unit for proper air flow and cooling. If the cassette is not going to contain a PCI adapter, use this same procedure to place an adapter filler panel in the cassette.
  1. Remove any shipping handles or brackets attached to the adapter.
  2. With the tailstock clamp in the open position, insert the adapter firmly into the tailstock retaining channel (A). See Figure 6.
  3. Rotate the adapter toward the top of the cassette and into place.
  4. Close the tailstock clamp.

  5. Position the adapter retainers to support the adapter, and then rotate the retainer clip (B) into the closed position. See Figure 6
    Note: Two retainers are located at the top of the cassette, along the top edge of the adapter. Two more retainers are located at the edge of the cassette opposite of the adapter tailstock. When the adapter retainer clip is in the horizontal position, the adapter retainers are unlocked and can slide toward the adapter. Place the retainers on the adapter according to the length of the adapter being used. Select the appropriate instructions:
    Adapter-cassette retainer placement for long adapters
    Place and lock the retainers (B). See Figure 7.
    Attention: Use of the lower corner support retainer might interfere with the docking of the PCI card when positioned within the system. Ensure the retainer does not interfere with the adapter connectors on the system backplane.
    
    Ensure the adapter edge is seated in each retainer groove (A). If the shape of the adapter or the presence of a connector will not allow the adapter edge to be seated into the retainer groove, ensure the retainer is still locked firmly against that edge or connector.
