ICL1 <--> ICL1
ICL ports can be used only with an ICL license. For more information license enforcement, see ”Licensed
features” on page 43. After the addition or removal of a license, the license enforcement is performed on
the ICL ports only when you enter the portDisable or portEnable commands on the switch for the
ports. All ICL ports must be disabled, and then re-enabled for the license to take effect. An ICL license must
be installed on both platforms forming the ICL connection.
There are two LEDs (a status LED and an attention LED) for each ICL connector port. Table 72 describes the
behavior of the LEDs.
The ICL ports appear as regular ports, with some restrictions. All port parameters associated with ICL ports
are static and all portCfg commands are blocked from changing any of the ICL port parameters. The
only management associated with ICL ports and cables is monitoring the status of the LEDs on the ICL ports
and any maintenance if the ATTENTION LED is blinking yellow. For additional information about the LED
status for blades and ports, see the relevant hardware document.
When you connect two HP StorageWorks Backbones, the following features are supported:
• 8 Gb/s speed
• Trunking
• Credit sharing
• QoS
