Table 2-12. 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. For general
information on installing this module, see "
Chassis I/O Module " in "Installing System Options."
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.
Gb Ethernet Pass-through Module
The Gb Ethernet pass-through module has 10 RJ45 ports. When installed in I/O 1 bay 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 2 -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 2 -13 lists the functionality of the Gb Ethernet pass-through module indicators. For additional
information on installing this module, see " Chassis I/O Module " in "Installing System Options."

Indicator Indicator Code
Fibre Channel indicator (green/amber) Off Power is off to the system.
Green/amber System has power.
Green/off Fibre Channel connection is online.
Off/amber The port is connected to a valid link partner on the network.
Off/flashing (twice per second) Connection has lost synchronization.
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.
NOTE: The Infiniband pass-through module uses small form factor 4x Infiniband connectors. To ensure proper functionality, use only cables provided
with the 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.
