About this task

Slot numbers

The following figure shows the HBA slot numbers.

The slot labeled N is the network daughter card, which contains ports ethMa, ethMb, ethMc, and ethMd. The management port ethMa is the first port set up by the Configuration Wizard. It is marked with a red rectangle in the figure below.

Port numbers

The following port numbering guidelines apply to all HBAs except the network daughter card:

• The physical interface name format for the remaining HBA slots is ethXy, where X is the slot number and y is an alphanumeric character. For example, eth5a.
• The direction of the port numbering on an HBA depends on the slot location and the type of HBA. Check the labels on each HBA before connecting cables.

Slot assignments

The following table lists the slot assignments for the supported HBAs. The HBAs are listed in priority order.

1. For 10 GBASE-T connections, use one of the following:
   • Unshielded Cat 6 cables with RJ-45 connectors that do not exceed 55m
   • Cat 6A cables with RJ-45 connectors that do not exceed 100m
2. For 10 GbE-SFP+ optical connections, refer to the list of qualified adapters and use an OM1 160 MHz (2 to 26m), OM1 200 MHz (2 to 33m), OM2 400 MHz, (2 to 66m), OM2 500 MHz (2 to 82m), OM3 1500 MHz (2 to 300m), or OM 4 3500 MHz (2 to 400m) SFP+ optical cable.
3. For FC connections, use a qualified Fibre Channel optical cable as described in the following table:
