4 Gbps Fibre Channel Pass-Through Module
The 4 Gbps Fibre Channel pass-through module provides a bypass
connection between a Fibre Channel mezzanine card in the blade and optical
transceivers for direct connection into a Fibre Channel switch or a storage
array (see Figure 1-40). The 16 pass-through ports on this module can
negotiate speeds of 1-, 2-, or 4-Gbps. The 4 Gbps Fibre Channel pass-through
modules are hot-swappable, and may be installed in Fabric B or Fabric C.
Table 1-22 lists the functionality of the indicators on each individual Fibre
Channel connector. For general information on installing this module, see
"I/O Modules" on page 296.
NOTE: To ensure proper functionality, use only the Short Wave Small Form Factor
Pluggable (SFP) transceivers provided with this module.
