Fibre Channel Pass-Through Module The Fibre Channel pass-through module provides a bypass connection between the Fibre Channel daughter card in the server module and optical transceivers for direct connection into a Fibre Channel switch or a storage array. (see Figure 1-12). The Fibre Channel pass-through modules are hot-pluggable. The Fibre Channel pass-through module in I/O bay 3 connects to port 1 on the optional Fibre Channel daughter card installed in a server module. The Fibre Channel pass-through module in I/O bay 4 connects to port 2 on the optional Fibre Channel daughter card installed in a server module. To provide redundancy, both I/O bay 3 and I/O bay 4 must have Fibre Channel pass-through modules installed. Table 1-11 lists the functionality of the Fibre Channel pass-through module indicators. For additional information on installing this module, see "Chassis I/O Module" on page 70. NOTE: The Fibre Channel pass-through module includes Short Wave Small Form Factor Pluggable (SFP) optical transceivers. To ensure proper functionality, use only the SFPs provided with this module.

Fibre Channel Pass-Through Module
The Fibre Channel pass-through module provides a bypass connection between the Fibre Channel
daughter card in the server module and optical transceivers for direct connection into a Fibre Channel
switch or a storage array. (see Figure 1-12). The Fibre Channel pass-through modules are hot-pluggable.
The Fibre Channel pass-through module in I/O bay 3 connects to port 1 on the optional Fibre Channel
daughter card installed in a server module. The Fibre Channel pass-through module in I/O bay 4
connects to port 2 on the optional Fibre Channel daughter card installed in a server module. To provide
redundancy, both I/O bay 3 and I/O bay 4 must have Fibre Channel pass-through modules installed.
Table 1-11 lists the functionality of the Fibre Channel pass-through module indicators. For additional
information on installing this module, see "Chassis I/O Module" on page 70.
NOTE:
The Fibre Channel pass-through module includes Short Wave Small Form Factor Pluggable (SFP) optical
transceivers. To ensure proper functionality, use only the SFPs provided with this module.
