Table 1-12. Fibre Channel Pass-Through Module Indicators
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 (1 Gb/sec or
2 Gb/sec) numbered 10 through 13, 10 internal ports, and
one 10/100 Mb Ethernet port with an RJ-45 connector.
See the documentation for your particular Fibre Channel switch module for the functionality and location of the switch module indicators.
Infiniband Pass-through Module
The Infiniband pass-through module provides a hot-pluggable bypass connection between the optional Infiniband Host Channel Adapter (HCA) daughter card
in the server module and the 4x Infiniband Transceivers for direct connection to an Infiniband switch. The Infiniband pass
-through module in I/O bay 3
connects to port 1 on the optional Infiniband HCA daughter card installed in a server module. The Infiniband passthrough module in I/O bay 4 connects to port
2 on the optional Infiniband HCA daughter card installed in a server module. To provide redundancy, both I/O bay 3 and I/O bay 4 must have Infiniband pass-
through modules installed.
Gb Ethernet Pass-through Module
The Gb Ethernet pass-through module has 10 RJ-45 ports. When installed in I/O 1 or I/O 2 bay, the Gb Ethernet pass-through module provides a connection
between the server module and an external Gb Ethernet device. When installed in the I/O 3 bay or I/O 4 bay, the Gb Ethernet pass-through module provides
a connection between the optional internal Gb Ethernet daughter card in the server module, providing a direct connection into an external Gb Ethernet device
(see
Figure 1 -14 ). The Gb Ethernet pass-through modules are hot-pluggable. The Gb Ethernet pass-through module in I/O bay 3 connects to the optional Gb
Ethernet daughter card installed in a server module. The Gb Ethernet pass-through module in I/O bay 4 connects to port 2 on the optional Gb Ethernet
daughter card installed in a server module.
Table 1 -13 lists the functionality of the Gb Ethernet pass-through module indicators. For additional information on
installing this module, see your Installation and Troubleshooting Guide.

NOTE: The Fibre Channel switch module includes Short Wave Small Form Factor Pluggable (SFP) optical transceivers. To ensure proper functionality, use
only the SFPs provided with this module.
NOTE: The Infiniband pass-through module uses small form factor 4x Infiniband connectors. To ensure proper functionality, only use Dell-provided cables
for this module.
NOTE: If you require service, technical support, or parts replacement for your Topspin Infiniband product, contact Topspin Support Services directly at 1-
800-499-1473 or through www.topspin.com.
NOTE: Only connect the Gb Ethernet module to 1000-Mb external switch ports. Do not use this module with 10-Mb or 100-Mb external switch ports.
