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.
Switch connection
See the hardware reference manual of your specific switch for 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
• 1 km at 8 Gbps
• 1 km at 10 Gbps
• 1 km at 16 Gbps
For more information on extended ISL modes, which enable long distance inter-switch links, refer to
Chapter 25, “Managing Long-Distance Fabrics”.
