Replacing a PCI express adapter: 2145-DH8

You might need to replace a PCI express adapter on a SAN Volume Controller 2145-DH8 node.This procedure is for a Tier 1 customer replaceable unit (CRU). Replacement of Tier 1 CRUs is your responsibility. If IBM® installs a Tier 1 CRU at your request, you are charged for the installation. Service agreements can be purchased so that you can ask IBM to replace these units.

Before you begin

This service action applies to SAN Volume Controller 2145-DH8 PCI express adapters:

10 Gbps Ethernet adapter
Compression accelerator adapter
Fibre Channel adapter
SAS adapter

About this task

This service action assumes that the node was turned off and removed from the rack, and the SAN Volume Controller 2145-DH8 PCI express adapter was removed. The adapter is replaced in the same slot from which the same type of adapter was removed. For details about supported adapter types for each expansion slot, see the information about optional features.

Some cluster solutions require specific code levels or coordinated code updates. If the device is part of a clustered system solution, verify that the latest level of code is supported for the clustered system before you update the code.

Procedure

To replace an adapter that was removed previously, follow these steps:

Install the adapter in the expansion slot, as shown in Figure 1.
1. Align the adapter with the PCI connector on the riser card and the guide on the external end of the riser-card assembly.
2. Press the adapter firmly into the PCI connector on the riser card.
Figure 1. Inserting the adapter into the PCI connector
Align the PCI riser-card assembly with the selected PCI connector on the system board:
- Fit the two alignment slots on the side of the assembly onto the two alignment brackets on the side of the chassis.
- Align the rear of the assembly with the guides on the rear of the node.
Press down on the assembly. Make sure that the riser-card assembly is fully seated in the riser-card connector on the system board.
Install the node cover.
Slide the node into the rack.
Reconnect the external cables, then, reconnect the power cords and turn on the peripheral devices and the node.
