Basic connections
Before connecting a switch to a fabric that contains switches running different firmware versions,
you must first set the same port identification (PID) format on all switches. The presence of
different PID formats in a fabric causes fabric segmentation.
• For information on PID formats and related procedures, refer to Chapter 3, “Performing
Advanced Configuration Tasks”.
• For information on configuring the routing of connections, refer to Chapter 4, “Routing Traffic”.
• For information on configuring extended inter-switch connections, refer to Chapter 23,
“Managing Long Distance Fabrics”.
Device connection
To minimize port logins, power off all devices before connecting them to the switch. When powering
the devices back on, wait for each device to complete the fabric login before powering on the next
one.
For devices that cannot be powered off, first use the portDisable command to disable the port on
the switch, connect the device, and then use the portEnable command to enable the port.
