2.7.3 PCIe Configuration

Default configuration is:

• Upstream port (root complex) at PCI Express switch PEX port 8 (AMC B2)

• No Non-transparent bridge port defined

To change the upstream port (and NT-bridge port), use the following CLI command in pri-

viledged mode:

set board pcie upstream <port>

set board pcie upstream <port> nt-bridge <port>

Where <port> can be amcb1, amcb2, amcb3, amcb4 or update.

After changing the upstream/NT port, the PCIe subsystem requires a reset. This can be done

by deactivating and activating the AT8402 carrier.

For an overview of the current configuration, use the CLI boardinfo command:

(Ethernet Fabric) #show boardinfo pcie

For additional information on the system configuration, refer to the "AT8402 CLI Reference

Manual".

2.7.4 SAS Configuration

The LSISAS1064E SAS controller is pre-installed with a firmware supporting an Initiator/Target

configuration. An alternative version provides integrated RAID support.

The SASx12A edge expander has appropriate configuration data pre-installed. In this default

configuration, all AMC bays are connected to the SAS Expander (SAS Connect).

To establish a storage connection between AMC bays 1 and 3 instead (Direct AMC Connect),

use the following command:

set board storage connect amcb3 amcb1

To reset the configuration to the default settings for bays 1 and 3, use the following command:

set board storage connect amcb3 sas

To establish a storage connection between AMC bays 2 and 4, use the following command:

set board storage connect amcb4 amcb2

To reset the configuration to the default settings for bays 2 and 4, use the following command:

set board storage connect amcb4 sas
