The two (2) drive loop extension modules provide the connectivity to
expansion FC SBODs either through the extension ports (CH2 & CH3)
and/or additional channels (CH4 & CH5) that are manually assigned as
drive loops.
NOTE:
The two channel pairs are intentionally separated on two I/O
modules; CH2 and CH4 reside on one module, CH3 and CH5 on
another. The intention of this cross-module routing is to avoid the
chance of link failure if an entire I/O module should fail.
These modules are secured to the chassis by retention screws. Each
module has four (4) SFP ports. 4Gbps SFP transceivers should be
separately purchased.
