The FC8-64 high density port blade cannot use the standard LC cables because the
pitch between optics in the new mSFP transceiver is smaller than in standard SFPs.
Patch cables and panels can be used to attach standard size cabling to the blade if
necessary. Figure 16 illustrates the mSFP to SFP patch cable. The mSFP transceivers
are used only with the FC8-64 port blade. Narrower OM-3 LC cables are used to
connect the FC8-64. These cables are offered by several major manufacturers.
Contact your IBM representative for options regarding different cable and patch
panel configurations to simplify cable management with higher density FC8-64
port blades.

Note that the duplex clip on the mSFP end of the cable is black for easier
recognition.
If ISL Trunking is in use, group the cables by trunking group. The ports are
color-coded to indicate which ports can be used in the same ISL Trunking group:
eight ports marked with solid black ovals alternate with eight ports marked with
oval outlines. See Table 25 on page 132 for a listing of supported cable speeds and
distances.
Optional inter-chassis link cables (ICL) can also be installed between SAN384B-2
chassis. See “Removing and replacing inter-chassis link (QSFP) cables” on page 93
for instructions on installing these cables.
