Fibre Channel Switch Module
You can install one or two hot-pluggable Fibre Channel switch modules in I/O bay 3 and I/O bay 4,
beginning with I/O bay 3. You must also install a Fibre Channel HBA daughter card in the server module.
The Fibre Channel switch module includes four external autosensing Fibre Channel ports numbered 10
through 13, 10 internal ports, and one Ethernet port with an RJ-45 connector. All the external ports operate
at

NOTE:
The Fibre Channel switch module includes Short Wave Small Form Factor Pluggable (SFP) optical
transceivers. To ensure proper functionality, use only SFPs provided with this module.
Infiniband Pass-through Module
The Infiniband pass-through module provides a bypass connection between an optional Infiniband Host
Channel Adapter (HCA) daughter card in the server module and 4x Infiniband Transceivers for direct
connection to an Infiniband switch. The Infiniband pass-through modules are hot-pluggable. To provide
redundancy, both I/O bay 3 and I/O bay 4 must have Infiniband pass-through modules installed. In this
configuration, the module in I/O bay 3 connects to port 1 on the Infiniband HCA daughter card; the
Infiniband pass-through module in I/O bay 4 connects to port 2 on the Infiniband HCA daughter card.
