Removing and installing inter-chassis link (ICL) cables
Note:
ICL ports can be used only with an ICL license. After the addition or
removal of a license, the license enforcement is performed on the ICL ports
only when the
portDisable
and
portEnable
commands are issued on the
ports. An ICL license must be installed on all systems forming the ICL
connection. The systems can be any combination of up to three SAN384B
and SAN768B chassis.
Attention:
If ICL cables are not in use, the ports must have EMI plugs installed to
meet EMI and other regulatory certifications.
Table 17 describes the ICL connector port LED patterns and the recommended
actions for those patterns.

Figure 44 on page 85 shows the two ends of an ICL cable. The ICL cables (2 meters
long) and the ICL connectors are color-coded and labeled for ease of installation.
The cables can connect ICL connector ports on the SAN384B core switch blades
(CR4S-8) or SAN768B core switch blades (CR8).
