Fibre Channel Pass-through Module
The 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 3-7). The 16 pass-through ports on this module can negotiate speeds
of 1-, 2-, or 4-Gbps. The Fibre Channel pass-through modules are hot-
pluggable, and may be installed in Fabric B or Fabric C.
NOTE:
No configuration is required for this module.
NOTE:
To ensure proper functionality, use only the Short Wave Small Form Factor
Pluggable (SFP) transceivers provided with this module.
