PCI-X adapter replacement

Note:

Use this procedure only when you are replacing an adapter with an identical adapter. If you are
replacing an adapter with an adapter that is not identical to the adapter removed, go to “PCI-X
adapter removal” on page 328 and “PCI-X adapter installation” on page 329.

To replace a PCI-X adapter, do the following:

1. Open the front and back rack doors and place the system into the service position as described in

“Placing the NAS Gateway 500 into the service position” on page 312.

2. Remove the service access cover as described in “Service access cover removal” on page 314.

3. See “PCI-X hot-plug manager access” on page 324, and follow the steps in the access procedure to

select

PCI-X Hot Plug Manager

. Then return here to continue.

4. Determine which adapter you plan to replace. Record the slot number of each adapter being

removed.

Note:

Adapter slots are numbered on the rear of the system unit.

5. Ensure that any processes or applications that might use the adapter are stopped.

Note:

Removing a PCI-X adapter requires the system administrator to take the PCI-X adapter offline
before performing any PCI-X adapter hot-plug procedures. Before taking an adapter offline, the
devices attached to the adapter must also be taken offline. This action prevents a service
representative or user from causing an unexpected outage for system users.

6. From the PCI-X Hot-Plug Manager menu, select

List PCI-X Hot-Plug Slots

. This provides a

descriptive list of all six slots in the NAS Gateway 500, and the device names in each slot. Record all
of the device names associated with the slot to be emptied, in the sequence shown.

7. From the PCI-X Hot-Plug Manager menu, select

Unconfigure a Device

. This step must be

completed successfully before starting any removal or replacement operation. If this step fails, the
customer must take action to release the device.

a. Press F4 to display the Device Names menu or type it in. Select the (rightmost) reported device

name associated with the adapter that you are removing.

and press

Enter

to display the Replace/Remove

a PCI-X Hot-Plug Adapter menu.

10. Move the cursor to select the adapter that you are removing, and press

Enter

11. Press the Tab key until the entry field displays the replace operation, and then press

Enter

. Follow

the instructions that are displayed on the screen until you are instructed to remove the adapter.

12. The selected PCI-X slot will go into the Identify state. Press

Enter

again. The selected PCI-X slot will

go into the Action state. See “Component LEDs” on page 384.

Note:

Before handling the adapter, be sure to use your electrostatic discharge strap to minimize
static-electric discharge. See “Handling static-sensitive devices” on page 310.
