Transceivers provide optical connections to external devices for both SWL and LWL connections.
Replace transceivers with a new pluggable unit rather than replacing the switch module. Refer to
the manufacturer’s instructions when installing transceivers.
“Removing and replacing the converged network switch” on page 25 provides details about
removing transceivers from the converged network switch.
ISL trunking groups
If you have purchased an ISL Trunking license for your converged network switch, external FC ports
can form trunking groups of ISLs between adjacent switches. Ports that can be used within the
same trunking group are color-coded on the switch module’s port side for easy identification.
All four external FC ports (0, 25-27) can be formed into a single 4-port trunk if the attached switch
supports an 4-port trunk. The ports can also form 2-port or 3-port trunk as well.
NOTE
Only the external ports are available for trunking.
Optional features
The converged network switch supports the following optional software, which is activated with the
purchase of the corresponding license key. Applicable options depend on whether the switch
module operates in NPIV or full fabric mode.

NPIV mode

Full fabric mode
