Note that the duplex clip on the mSFP end of the cable is black for easier
recognition. See Table 28 on page 152 for a listing of the qualified mSFP optical
cables for the FC8-64 port blade.
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.
Table 28 on page 152 provides a listing of supported cable speeds and distances.
Optional inter-chassis link cables (ICL) can also be installed between SAN768B-2
chassis. See "Removing and replacing inter-chassis link (QSFP) cables" on page 113
for instructions on installing these cables.
