Adapter Slots and Associated Fabrics
The adapter slots 51 through 54 of system enclosures have the following access to
ServerNet fabrics.
In processor enclosures:
•
In PMF 1 CRUs, slot 51 is single-ported and accesses only the X fabric. This slot is
usually reserved for SEBs or filler panels. In PMF 2 CRUs, slot 51 is dual-ported.
•
In PMF 1 CRUs, slot 52 is single-ported and accesses only the Y fabric. This slot is
usually reserved for SEBs or filler panels. In PMF 2 CRUs, slot 52 is dual-ported.
•
Slots 53 and 54 are both dual-ported:
°
Single-ported adapters in slot 53 access only the X fabric.
°
Single-ported adapters in slot 54 access only the Y fabric.
°
Dual-ported adapters in slots 53 and 54 access both fabrics.
In I/O enclosures:
•
Slots 51, 52, 53, and 54 are all dual-ported:
°
Single-ported adapters in slots 51 and 53 access only the X fabric.
°
Single-ported adapters in slots 52 and 54 access only the Y fabric.
°
Dual-ported adapters in slots 51, 52, 53, and 54 access both fabrics.
Note. ServerNet adapters can replace SEBs or MSEBs in slots 51 and 52, but then it
would not be possible to expand the system to more than two processors.
