4. Power off the switch.
Basic connections
You can make basic connections to devices and to other switches.
Before connecting a switch to a fabric that contains switches running different firmware versions,
you must first set the same 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, see Chapter 2, “Performing Advanced
Configuration Tasks”.
• For information on configuring the routing of connections, see “Routing Traffic” on page 59.
• For information on configuring extended interswitch connections, see “Managing Long
Distance Fabrics” on page 455.
Device connection
To minimize port logins, power off all devices before connecting them to the switch. For devices
that cannot be powered off, first use the portDisable command to disable the port on the switch,
and then connect the device. When powering the devices back on, wait for each device to complete
the fabric login before powering on the next one.
Switch connection
See the hardware user’s guide of your specific switch for interswitch link (ISL) connection and cable
management information. The standard or default ISL mode is L0. ISL Mode L0 is a static mode,
with the following maximum ISL distances:
• 10 km at 1 Gbps
• 5 km at 2 Gbps
• 2.5 km at 4 Gbps
ISL mode L0 is available on all Fabric OS releases. When you upgrade from Fabric OS v5.3.0 to
Fabric v6.0 or later, all extended ISL ports are set automatically to L0 mode.
For more information on extended ISL modes, which enable longer distance interswitch links, see
Chapter 20, “Managing Long Distance Fabrics”.
