How to enable a port

1. Connect to the switch and log in as admin.

If the port is connected to another switch, the fabric might reconfigure. If the port is connected to one or
more devices, these devices become available to the fabric.
If you change port configurations during a switch failover, the ports might become disabled. To bring
the ports online, reissue the portEnable command after the failover is complete.

Making 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, refer to
For information on configuring the routing of connections, refer
For information on configuring extended interswitch connections, refer
on page 341.

Connecting to devices

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.

Connecting to other switches

Refer to the your switch installation guide for interswitch link (ISL) connection and cable management
information. The standard (default) ISL mode is L0, which you can configure with the
portCfgLongDistance command. ISL Mode L0 is a static mode, with the following maximum ISL
distances:
• 10 km at 1 Gbit/second
• 5 km at 2 Gbit/second
• 2.5 km at 4 Gbit/second
ISL mode L0 is available on all Fabric OS releases. When you upgrade from Fabric OS 4.0.0 to Fabric
4.1.0 or later, all extended ISL ports are set automatically to L0 mode.
For information on extended ISL modes, which enable longer distance interswitch links, refer to
